| I thought I would copy a link here to an article about this therapy, I found it really interesting - hope you do to. http://www.medpagetoday.com/Neurology/G ... logy/17709 (external link, opens new browser window) I am a few weeks from the end of my double blind Neramexane trial, after which I start the open label trial. I will post with news if and when I have some. Happy new year everyone! Kath | kathy-b | 29 Dec 2009 22:14 |
| Looking forward to hearing your Neramexane results. Best of luck and best wishes. S.D | S.D | 29 Dec 2009 22:48 |
| I'm not waiting for Audiologist / Ent 's 2 or 3 more years to start this treatment! I'm starting it right now DIY! I'm into music production and know my T frequencies and how to notch them out using High quality EQ's! Any music producers and technical persons please keep on posting!! Let's not cry ourselves of what have happened to us but instead find a remedy!!! Steve | 31 Dec 2009 10:24 | |
| Hi As a relative newcomer to these forums and to T, do I assume that threads such as these suggest that TRT has been tried without success? | 31 Dec 2009 10:37 | |
| Steve, do you have any PC based software that can process a selection of mp3 files? | 31 Dec 2009 10:38 | |
| you can use any music production Digital audio workstation (DAW) that there is on the market such as : Apple logic : Mac. PC : Cubase, Ableton live, FL Studio to name a few.... You need a parametric equaliser and notch out the unwanted frequencies carefully... I hate it when a news like this gets on to the media with very good result and people like us who are constantly suffering to not have DIRECT ACCESS to it! I think this should be made possible to all people suffering from T as soon as possible [ and not thinking of marketing procedures so that the medical industry gets another opportunity to cash in more money). In my opinion this is a Human Right to get treatment ASAP | 31 Dec 2009 11:45 | |
| I am also going to try this. I have been using music production software for years so don't think I will have a problem notching the correct frequency out. Will let you know how I get on. | Saul | 31 Dec 2009 13:03 |
| Yeah let's keep in touch! if you have msn messenger mine is stevenpsaila1986@hotmail.com Cu there and let's beat this NOISE!!!! steve | 31 Dec 2009 17:40 | |
| How can I determine what are my T frequencies. I've had this condition for over a year and it seems to have localized in my right ear with a constant pitch? I've calmed down a little about trying everything to stop it, but this sounds good and I love music. | 02 Jan 2010 10:24 | |
| I was also interested in how one would go about pitching their tinnitus and stumbled across this site, http://www.yourtinnitus.com. (external link, opens new browser window) I have not yet gone through the process of ordering anything from here yet however. Kathy | kathy-b | 02 Jan 2010 13:00 |
| This is interesting. Does anyone know if the theory behind this is similar to Neuromonics? | KiminHouston | 03 Jan 2010 06:13 |
| Here's a site that you can test your T Frequency. http://audiorelief.co.uk/en/tinnitus_test.html (external link, opens new browser window) free, then they try to sell you. I would love to see a site where one's music could be easily notched once the frequency is determined. Charlie | 03 Jan 2010 07:55 | |
| I determined that my T Frequency is 5800Hz at http://audiorelief.co.uk/en/tinnitus_test.html (external link, opens new browser window) and I'm wondering if this site has enough frequencies. Also, wondering what frequencies others are hearing. Charlie | 03 Jan 2010 08:04 | |
| My frequency is 9000Hz using the same site. I don't think that the site has sufficent frequencies. Had T for must be 5yrs now. Volume is is not constant and seems to vary with how well I slept. However the frequency is constant. | Damian | 03 Jan 2010 10:43 |
| Thanks for the comment Damian. I agree with Steve that it is very possible to notch music with the proper equipment by ourselves I'm wondering whether it can be done online? If there would be copy write issues,etc Charlie | 03 Jan 2010 11:47 | |
| There are a lot of open source audio libraries out there. Simply adding a notch-filter for a particular frequency range should be possible and then just a case of reprocessing the mp3/flac/ogg file. Due to the UKs archaic copyright laws just copying a CD/tape is illegal so doing the process online is also likely to be illegal as well, though I suspect that if it went to court and you demanded jury trial you would get off (I'm not a lawyer...). To be honest working out the T frequencies accuratly and consistenty is likly to be more difficult and rather subjective. Sadly I do not have time to look into modifying an open source app any time soon. However if anyone can find out how the study assessed the T frequency of the subjects this would help in producing something useful. Regards Damian | Damian | 03 Jan 2010 12:00 |
| This blog has some interesting suggestions for the more technical: http://www.geoffreyfalk.com/wp_blog/?p=4079 (external link, opens new browser window) It also has a link to the original paper! | Damian | 03 Jan 2010 12:21 |
| Guys this is Steve Again! I'm seeing a light at the end of the tunnel! My earsare not getting fatigued so easily and i can turn up the volume as well which indicates it is not affecting my hyperacusis!! (not exceeding 70db, BE CAREFUL!!) and i returned to listen to my favourite dance music which is TRANCE!!!! | 03 Jan 2010 13:20 | |
| Steve, Are you removing your T frequences? Regards Damian | Damian | 03 Jan 2010 14:25 |
| I found what appears to be a better test here: http://www.digital-recordings.com/tinni ... ducts.html (external link, opens new browser window) http://www.digital-recordings.com/tinni ... nitus.html (external link, opens new browser window) Have not yet tried the web version as there is a little bit too much noise in the house and I need a set of headphones. | Damian | 03 Jan 2010 16:02 |
| yeah damian of course, i have a complex tinnitus sound which is between 4000 and 5000 HZ and i elimintaed those frequenices | 03 Jan 2010 21:55 | |
| Here's an interesting article on the same subject http://bit.ly/7c8IuR (external link, opens new browser window) Damian I couldn't get the test site to work for me, but I'm assuming that if an octave is taken out of the music, that would leave a lot of room to play with even if I'm not able to determine my T Frequencies at 100% accuracy. Steve-could you tell us how you were able to notch your music playlists. Charlie | 04 Jan 2010 05:49 | |
| I tried and failed to get the test site to work too. I emailed them and they replied saying that the site was being upgraded and the tests would not work for now. | 04 Jan 2010 08:21 | |
| I've been working all morning with the latest version of audacity to remove T frequencies. Under Effects there is a notch filter command which I used, but wasn't able to tell how big a notch, so to speak, that I made. Under effects there is also a command Remove Vocals(for center-panned vocals). Here I was able to plug in some frequencies for removal, but there was no way to confirm what I had done and I couldn't tell the difference in the music just by listening. I wrote to Audacity and am waiting for an answer. There seemed to be a lot of enthusiasm about this subject a few days ago, but it seems that it has died down and people with knowledge aren't speaking up. Charlie | 04 Jan 2010 12:41 | |
| I find this very interesting. I recently treid the opposite approach, and found to my BIG surprise that it really worked, check out this site and try with a set of headphones http://lets-beat-tinnitus.co.uk/blog/fr ... e-therapy/ (external link, opens new browser window) I found it moste effective when I have a spike, I use it every morning. To notch out feq on a playlist using winamp is very simple, You can buy the plugin mentioned on this site : http://www.geoffreyfalk.com/wp_blog/?p=4079 (external link, opens new browser window) its made for winamp You can also do it free, here´s what to do if you are on a PC 1. get winamp, and install 2. get VST Winamp Bridge, and install http://www.winamp.com/plugin/vst-winamp-bridge/146317 (external link, opens new browser window) 3. get a free VST notch filter/eq and unpack it to a folder on your drive http://www.rs-met.com/ (external link, opens new browser window) here is one called EasyQ it has a notch setting 4. open winamp, go to options, then preferences, select DSP/Effects in the drop down menu on the left side, On the right side you can see the VST Host DSP, click on it and choose Configure active plugin Now a little box will appear, left click in the little gray box and choose Load dll, guide it to the folder with the EasyQ, in that folder there is a file called EasyQ.dll, when you choose that one your EasyQ will appear Right click in the white area and choose Notch To cut out frequency you have to be under zero If you wanna reset your configuration of the plugin, left click on the name EasyQ in the upper left corner and choose reset | 05 Jan 2010 00:06 | |
| Use bandwith to determin the curve off your cut | 05 Jan 2010 00:12 | |
| What frequencies did you remove? The parties involved in the test said that they removed an octave of sound according to the subjects' T frequency. Do you know how, half octave above or half octave below or what? ...and how did you verify that the notch was made in your music? I also downloaded this Tone Generating Software and was able to approximate my T Frequency at around 6727 Hz. http://www.nch.com.au/tonegen/index.htm ... zAodw1WCMg (external link, opens new browser window) Charlie | 05 Jan 2010 09:34 | |
| Could somebody clear this up for me. I've read most of the articles on the Web regarding this subject, including the abstract by the authors of the study. Here http://bit.ly/6kCpl9 (external link, opens new browser window) they say "we attempted to reduce tinnitus loudness by exposing chronic tinnitus patients to self-chosen, enjoyable music, which was modified (“notched”) to contain no energy in the frequency range surrounding the individual tinnitus frequency" and here http://bit.ly/5bH9rh (external link, opens new browser window) they say "Notched noise and notched music were prepared from white noise (sampling rate: 44,100 Hz) or normal music (sampling rate: 44,100 Hz) by eliminating the one octave wide frequency band centered at 4 kHz" I believe the first to be correct and have been able to notch music for both, but would like to be sure since I've found some articles that have come out and said that one octave was removed | 07 Jan 2010 09:14 | |
| Well it seems that the excitement at the beginning of this forum has died down. I would really appreciate it if someone could answer my post (above) and maybe write a little about their experience listening to notched music. | 13 Jan 2010 17:35 | |
| http://www.nch.com.au/tonegen/index.html (external link, opens new browser window) This tone-generator allows you to make tones to semitones or more precisely to the exactly frequency and you can play multiple tones at once. Once you have the tones you get a 30-50 band equaliser on your PC, and remove your hurtful frequencies and listen to it through that from then on. | Mark | 13 Jan 2010 17:46 |
| Noticed Neramexane mentioned at the start of thread, this is an NMDA Antagonist, a class of anaesthetic, Ketamine is another. Otherwise known as Special K amongst others, its well-known as a dangerous and highly addictive drug and mainly used as an animal tranquilliser. Dont want to put anyone off, but I would be very wary, if offered this treatment, research and ask questions, it sounds like a very last resort. | Janb | 14 Jan 2010 20:45 |
| I think the notched music should be played in mono so that both ears hear identical input. Meia players, headsets etc all seem to be in sterio. Can anyone suggest how I can get a mono output. | 17 Jan 2010 21:52 | |

| I believe that you can notched the music in mono. There should be a setting on your software for this. None of us are sure about this whole process though and I've been trying to get a clear confirmation as to how they proceeded with the original trial. Help! Charlie | 18 Jan 2010 10:22 | |
| Charlie – hope this helps. The paper can be purchased for $10 at PNAS (easy to find on google) and is titled “Listening to tailor made notched music reduces tinnitus loudness and tinnitus-related auditory cortex activity. There has been no discussion of the auditory cortex activity on the forum but in many ways it is the most interesting finding as it shows that the brain itself rather than just the ear changes. Apparently in the trial which has sparked our interest, (I suggest reading the original paper above rather than this précis which may contain errors), a group who had unilateral/strongly lateralized, chronic > 12months, tonal tinnitus at a frequency of less than 8kHz and with no severe hearing loss or neurological or psychiatric complications were exposed to notched music for twelve months. The subjective tinnitus frequency was measured by matching it ipsi-laterally to a pure tone, at least four times and on two different days and taking the median. Loudness was measured on an analogue scale for future comparison. The patients favourite music was used, with a one octave band removed centred on the tinnitus frequency but there is no mention of the “Q” of this band. The music delivered to both ears was filtered identically (therefore one assumes it was identical and not stereo). If any one can interpret the phases “unilateral/strongly lateralized” and “ipsi-laterally” unambiguously and in simple language it would help. Regards | 22 Jan 2010 15:04 | |

| I wrote to the Group that did the trial, but the answer that I got was to follow their progress on their website www.tinnitus.uni-muenster.de The website is in German but it is easy to translate using Google Translate. I appreciate what you've written but realize that it's not going to be so easy to replicate the trial. I've been listening to notched music for a couple of weeks now, but not with an octave taken out. I think that my Tinnitus Frequncy is 6727Hz.I'm going to try taking out a whole octave and changing the music from Stereo to Mono. Removing a whole octave(centered) means that I would be removing from 5044Hz to 10090Hz. Anyone else trying this with any luck? I think that unilateral/strongly lateralized” and “ipsi-laterally” means doing the same to both ears. | 25 Jan 2010 21:22 | |
| I personally think that a whole octav is a bit much, I would simply take out the frequency and some bits around that. Like you say, an octav at that band, is removing 5000hz. Use the notch filter and just take out 500 on each side and you should be able to tell the difference but at the same time enjoy the music while training you brain not to pay attention to those frequencies anymore. Make sure to check it afterwards in an 30-50 band equaliser to ensure that it is actually removed. I think the ipsi-laterally refers to the patient group who have equal tinnitus in both ears. Filtered identically means that that both ears were notched to the same level and frequency. | Mark | 26 Jan 2010 20:41 |
| This is all very interesting and has given me real hope that I can at least reduce the loudness of my Tinnitus. I've just installed Audacity on my Mac and have run the filter to get rid of my frequency of 7250hz. Having said that, I've tried a couple of the online tone tests and downloaded the generator. I was sure my freq was 7250 but then it sounds like 10k and 14k+ ... I guess it could be my cheap earphones and maybe I should go for a proper test. | 26 Jan 2010 22:28 | |

| Mark, I agree an octave sounds like a lot, along with listening in Mono. Up until yesterday, I was listening and enjoying music in stereo with a much smaller notch. I went back to the three samples of music that the researchers used http://www.pnas.org/content/107/3/1207/ ... pplemental (external link, opens new browser window) and it sounded to me like an octave was taken out. I would prefer a smaller notch, since the listening experience is so much better, but would also like to reap the benefits of the trial. These three samples are presented as videos and I haven't had the time or have the experience to check the audio in the 'Plot Spectrum' in Audacity. Dave-I had the same trouble trying to localize the T frequency. I'm planning on getting an expert opinion. I find it sort of strange that my T frequency is higher than the range that I can actually hear in my right ear. Charlie | 27 Jan 2010 07:33 | |
| I separated the audio out of the sample music and it is obvious that an octave was removed. I did same with the Placebo Notched music and it looked identical and sounded identical. So what is their magic formula? Charlie | 28 Jan 2010 12:43 | |
| Hi Charlie, To find your frequency, set up a tone generator and make it so either you are not able to see the actual frequency as you scroll the band or b. you have someone do it for you. Repeat this as many times as it takes for you to get a good mean value. I would say that would be a good start to finding your frequency? The placebo and notched music was identical. Perhaps they loaded the wrong file or perhaps the placebo and target were both given the same as the placebo might as well be in the same frequency range as target? I dont know because the test concludes that normal music does not support the "Zwicker effect" anyway. This is basically a piece of supporting research, based on the Zwicker E, 1964 research, where samples of white noise with an octave missing was presented to a person. The person would after hearing the noise with the octave missing hear a "Zwicker tone", a tone like tinnitus. This is interesting because it is as if the brain has decided that something is missing in the white noise and replaced it with what it thinks is correct. After the tone is gone, the tone continues in the head for a few seconds, like tinnitus, but not forever. The second part of the trial is reproducing the "Zwicker tone" using notched music. That did not produce the "Zwicker tone". In other words, if you listen to notched white noise you might get tinnitus? And how does the brain then know the difference between music and noise? The whole research around Zwickner is quite interesting. Perhaps there is a way to un-learn your brain to tune in to Tinnitus? And notched music is that way? | Mark | 28 Jan 2010 20:09 |
| I've justpicked up on this thread which I find very interesting. I've been an audio enthusiast for many years (have engineering training) and firmly believe that a way to reduce sound induced tinnitus is via controlled sound therapy. However, my assumption was that exposing yourself to a low level of the tinnits frequency was the answer. I've found that if I do this using an (analogue) signal generator and sweeping around the frequency a little then the tinnitus virtually disappears for a short time. This notch idea may be better though - I'd assumed that the brain was replacing the missing (damaged) frequency with. the tinnitus so if I replaced it with the sig gen instead then maybe the brain would be fooled and switch off the tinnitus frequency. But maybe I'll now try the notch idea...... | bassman | 28 Jan 2010 23:47 |
| Can anyone recommend music-notching freeware for Mac OS X, please? WitD. | Whistling in the Dark | 01 Feb 2010 13:19 |
| http://audacity.sourceforge.net/download/ (external link, opens new browser window) you may have to add some files manually for their notch filter, but their help file is very good. To see the notch you'll have to go to Analyze-Plot Spectrum and set the Size to 16384 and Axis to Log Frequency | Charlie | 03 Feb 2010 07:37 |
| I recommended using audacity for notching, but the program doesn't let you plug in the proper frequency. You must put in a number for Notch Q and hope that you get a full octave. Is anyone using a program that let's you fill in the proper frequency? ...and it is really necessary to play the music in Mono if you only have hearing loss and ringing in one ear? Help!! | Charlie | 03 Feb 2010 17:53 |

| Winamp have a very good 250 band equalizer which can be used to notch music as you wish. You get to it via "options", "DSP/Effects" - it maybe only on the latest version of winamp. I can now edit any music I like and play it through my computer with the notch. The problem is I can not save this edited music but have to regenerate it each time and can only listen to it from the computer. Does anyone know how the edited version can be burned onto a CD or MP3 player. If anyone wants exact detail on how to set up Winamp I will gladly tell you how I did it - it would be a long post | Rodney | 08 Feb 2010 14:22 |
| I went on the Audacity forum and found out that what I need is a Band Stop Filter. It is a plug-in and once installed all you have to do is put in your T-Frequency, the default is set for one octave and you've got it. The end result looks exactly like it would if you put in the frequency ranges on other programs. I've used another program 'til now and have seen some improvement, maybe it's just my attitude. This is totally unscientific, but any relief is welcome. Good Luck to all. If you need the band stop plug-in write to me a fogelre@gmail.com | Charlie | 23 Feb 2010 05:58 |

| When I bought a Mac about 3 years ago it came with Garage Band, which is a simple DAW (digital audio workstation). I'm not sure whether Garage Band's built in equalizer is adequate for this job, but if not, this site has tons of free plugins including equalizers... http://www.kvraudio.com/ (external link, opens new browser window) If anyone tries this, I would love to know what results you got from the experiment. | 23 Feb 2010 22:21 | |
| Hi Everyone, I've had Tinnitus for about 5 years. Drove me crazy! I'm not sure if the cause was loud noise or some kind of reaction to medication. Anyway, I recently got an appointment with a really great ENT doctor in Toronto, Canada. It took me almost a year to get an appointment with this guy! It was worth it though. Has anyone had their Tinnitus tested before? So he did this test and gave me a CD with white noise and calming sounds on it that were specific to my Tinnitus sound and it has helped a whole lot. It's definitely the most impressive thing I've tried so far. After I hit stop on the CD I can hear that the Tinnitus is gone for about 10 seconds and then starts to come back a bit. He said if I stay dedicated to listening to it, it can "retrain" the brain. Its definitely made a huge difference... Maybe this is the start of something amazing for us. Good Health Everyone! Carson carson.greole@gmail.com | 24 Feb 2010 00:56 | |
| I just saw this article about an iTouch/iPhone App http://prmac.com/release-id-10997.htm (external link, opens new browser window) What impressed me is that they have a Residual Inhibition Tone Generator see here http://innerearsolutions.com/Software_Solutions.html (external link, opens new browser window) and a long term training called Habituation I'm not sure what Habituation is but it seems like Residual Inhibition is what Carson is talking about. They say that listening to your matching tone for 10-20 minutes will leave you with a sense of relief for a short duration. Has anyone tried this long term? Regarding reproducing "Notched Music" and the perfect equalizer, the best solution, I believe would be to use a parametric equalizer, but I'm not sure that would remove all of the frequencies. I'm doing it myself manually and waiting to find a programmer and that speed up the process with a little automation. Stay in Touch, Charlie | Charlie | 26 Feb 2010 06:50 |
| Hi All I am very new to this only 6 weeks in still not able to sleep though the night yet but slowly adjusting and learning thanks to web sites like these.I am trying to reproduce notch music using the winamp method shown here is there any way of check you have notched out the correct Frequencies. or has anyone got a guide so I can check if I am doing it right. Please can some help Steve Steven.freeeman@tesco.net | Steve | 26 Feb 2010 10:35 |

| Hi All I would like to thank everyone for help on this forum. I have now notched and checked a large amount of my Music. Lets hope it helps many Thanks Steve | Steve | 01 Mar 2010 19:24 |
| I´ll try to answer as good as I can.. As I understand it, it was, a half octave above and a half octave below, equal to one octave I was able to hear the effect of the Eq(notched), but I had a very hard time determine what my T feq is so I gave up for now, my problem was that I always heard 2 or 3 tones at the same time, might give it a try again soon. I find the last bit a little confusing 1,"by eliminating the one octave wide frequency band" this would describe the curve of the equlizer, if so the equlizeren in the tip I provided above will not do the trick, we need and editor that can cut without a slope curve.. 2. "band centered at 4 kHz", This sounds really strange, wasent they supposed to customize each pice of notched music/noise to each person in the study, they cant all have had T at 4 khz!? hmm 3. "however, there was no significant difference between the normal music and the notched music conditions" This is clear, forget the notched music and work on removing frequency from white noise, white noise contains all frequency. Download white noise here http://www.simplynoise.com/download.htm (external link, opens new browser window) For wide frequency band removal Iam pretty sure Audacity can do it, however if it should be perfect a FFT tool would be best, I think thats what they used, Ill look in to that tomorrow If anyone would be interested | thomas | 01 Mar 2010 21:56 |
| Forget my post above I was trying to anwser a question asked long ago, I have not slept in 24 hours so I'm a little confused, tsk | thomas | 01 Mar 2010 22:01 |
| "They say that listening to your matching tone for 10-20 minutes will leave you with a sense of relief for a short duration. Has anyone tried this long term?" I tried a weekend to listen for 6-7 hours in a row for 2 days T still came back as fast as if I only used it for 10 min.

| Hi All I have managed to Notch and test my music but I have a question about how to listen to it. For this to work I assume you would need headphones which blank out any other sounds ie noise cancelling is this correct? can some let me know Steve | Steve | 06 Mar 2010 18:57 |
| Hi Steve, Noise canceling would be great, but I'm not sure if they are necessary. Actually, I believe since you are at this point like a lot of us, I would like to open the discussion up to where do go from here in regards to reproducing what was done in the original test. In other words, do we have to listen to the music in a totally quiet area, do we have to only concentrate on the music or can we read etc and does it matter if the music is in stereo or mono. I tried mono and with one octave removed and it is totally boring. I've been listening to music around the house, when I go for walks and when working out on a stationary bike. I'm probably doing it all wrong, but at this point most of the benefit is maybe from the music therapy. Charlie | Charlie | 09 Mar 2010 06:34 |
| Hi Charlie The reason I say this is if there are other noises you can hear the frequencies you have removed could be re-introduced could they not? I would also like to know if what we are all doing follows the study. I have also been experimenting with tones around my frequency I think mine is around 11000Hz. Which seem to cancel it out for short periods which I assume is the masking effect? Could you tell what the calculation is to remove one full octave? Could I send you a file to see if you think I have notched it correctly? I have been doing all my music in Audacity 1.3 Beta in Mono. I found this on a web site can anyone comment if this is correct? The upper and lower nominal octave band limits are arrived at by multiplying the centre frequency by 1.4142 and 0.7071 respectively Steve | Steve | 09 Mar 2010 09:11 |
| Hi Steve, The study used people as far as I could tell that had T but not hearing loss. They are doing more studies-see their website- http://www.tinnitus.uni-muenster.de/ (external link, opens new browser window) you'll have to use google Translate to read it, but German translates fairly well compared to other languages. Your T frequency seems kind of high. I would recommend asking your doctor to send you to a hearing testing facility that could help you identify the the tone. Or have someone help you using http://www.tucows.com/preview/240287 (external link, opens new browser window) I read that the ratio for finding an octave is 2:1 I received a file from one of the Audacity engineers that I'll send to you that does this automatically along with making the notch, you just have to plug in your T frequency. contact me at fogelre@gmail.com Charlie | Charlie | 10 Mar 2010 07:37 |
| Hi Everyone, I'm new to this forum, but it certainly looks interesting. My T (constant tone @ approx 13Khz) came on 2 years ago, I think shortly after a long haul flight. Been down the ENT route - they really weren't interested because I don't have hearing loss. I have two questions: (a) is using a PC sound card really up to the job? The sample rate is normally something like 44.1Khz which means high frequencies (say 10Khz and above) would, I guess, be rather approximate in terms of waveform shape. I'm interested in audio technology, so know my waveforms, and I'd say my T sounds more like square wave than sine wave, implying it has overtones above the fundamental frequency. Question is more general. Yesterday, for the first time in 2 years, my T seemed to go away and I had a new sense of clarity in my left ear. Unfortunately, today it was back to normal. Has this happened to anyone else? It's given me new hope that there is some underlying physiological cause (middle ear congestion or something) that can be addressed. I can also vary the volume of my T considerably by opening my jaw wide, which again makes me think physiology. Any suggestions would be welcome. Anyway, time to read the other posts and referenced papers carefully and see if I can have a go at "notching". Cheers, Neale | 10 Mar 2010 18:15 | |
| For the past 4 months my T has been louder than before (had T since 14 - so 20 years now). But in this 4 months i have had around 2-3 days of what you've described - almost like a fullness to the ear cleared and i could barely hear the T. I did make an effort for a few days before at least one of these times to drink a lot of water and watch my diet. In fact, when i was 14 and a couple of weeks before T started, i felt something wasn't right with my blood flow. I know that sounds weird, but was as if i needed more blood in my head!! T developed a couple of weeks after these feelings. I'd check out - blood circulation, TMJ etc. Seeing ENT Tuesday and going to have a long chat about this. Also seeing my dentist about a splint as i know i grind my teeth at night and have a slightly 'clicky' jaw (TMJ confirmed by maxillofacial surgeon, a dentist and a ENT medic). | 14 Mar 2010 18:07 | |
| Hi "For the past 4 months...". Well, that's quite interesting. I recently went for a comprehensive Bupa health check. I'm basically reasonably fit (6'1" 12.5 stone) - no cardio or blood level problems, but quite high bad cholesterol, so for a couple of weeks before my "clear" moment, I had been on a very low fat diet and, yes, probably drinking more water. I do also have a slightly dodgy jaw - I hear crunching (crenelation I believe they call it) but mostly in the opposite jaw. I had a bite guard made a few years ago because I had been clenching my teeth, I suspect because my TMJoint has gone a bit slack. I also realised recently that I can't easily "pop" the ear that went clear. So I'm wondering if there's some chronic eustachian tube issue that might be connected? Thinking of seeing a private ENT specialist... On the subject of notching etc, I've downloaded WinAmp, the VST feature and BugPass filter. As I suspected, at these higher frequencies (>10KHz) there's little original music and a lot of WMA/MP3 artifacts / possibly soundcard aliasing. I have to say an octave sounds way too much to take out - it would make the music sound pretty unpleasant. Think I'll have to try getting hold of some 96KHz FLAC files and processing/playing them on my music PC (equipped with Cakewalk Sonar and an E-MU 0404 card) which actually supports up to 24-bit/192kHz.

| Yesterday I had a hearing test to find my T Frequency. I originally self tested myself and thought it was 5800Hz, then I thought it was 4200 Hz. The test involved finding my T sound then my T frequency. We did the test three times and I came up 6000Hz twice and 4000 Hz the other time. Since I only hear T in my right ear, the technician put the sounds in my left ear. In between the frequency tests, I did a hearing test. The hearing test showed that I had some hearing loss, but only normal hearing loss for my age. Needless to say I'm in the process of re-notching my music to believe it or not 5800 Hz, but with the feeling this time that I'm closer to the frequency. | Charlie | 24 Mar 2010 10:46 |
