Hi
@sunmoon. Just a suggestion going forward on the forums - if you use tagging (e.g.
@earflappin, etc.) when asking a member a question it will be flagged so we see it on the login bar making it easier and faster for us to respond.
earflappin what do you think it's better ACRN or Notch for the treatment of T? they are two different treatment no?
Yes, they are two different treatments each backed with their own studies. Please understand all of us are different in the sense of how long we have had T, our T frequency(ies), loudness levels, how well we have habituated, etc. I say this because certain treatments may have higher efficacy depending on the type of T one has. In my case, my T Freq is 11.5khz, I have had it for over 3 years and I have substantially habituated. I was not aware of ACRN or notch therapy when I started my habituation. I just used white noise and it definitely helped me.
While I have tried ACRN and notch therapy recently, I have not given either long enough to form an opinion. All I can say so far is that neither have reduced my T loudness. Although, interestingly, my T frequency was shifted. When I started it was at 10khz and I find 11.5khz less obtrusive. Whether this will sustain itself I don't know. BTW, I use ACRN and notch together sometimes.
Bottom line, I have no data (yet) that would allow me to recommend ACRN vs notch. Perhaps other members will respond with their experience.
Earflappin I followed the steps, and when I get the item, Band-stop filter is not in the latest version for Mac, how do I do?
Go to this link:
http://wiki.audacityteam.org/wiki/Nyquist_Effect_Plug-ins#Band_Stop_Filter and download the plug-in. You'll need to put it in your c:\program files\audacity\plug-ins folder and restart Audacity.
You can adjust the stop band - if your T frequency is low (e.g. 4-5kz) I would first try 1 octave. Since mine is so high I use 0.25 octave so I maintain energy in the noise above my T frequency.
