Acoustic CR® Neuromodulation: Do It Yourself Guide

You may try this basic pattern of 13-14kHz followed with 30sec pause, see if it helps, this works for my tinnitus, but it could be that your tinnitus is specific.

Tinnitus sound therapy 13-14kHz - 15s tones +...

 

I hear nothing over 12k

 

There is a paper that is based on the same principal as acoustic CR neuromodulation, i.e. not stimulating the frequencies of the tinnitus but those adjacent ones, hoping that those adjacent ones will exhibit lateral inhibition and inhibit spontaneous firing of cells responsible for the tinnitus.

Only in this case they recommend listening to the music and remove the frequencies of your tinnitus in the music file. I used Audacity to remove +/-0.5kHz near my tinnitus frequency, maybe you can try similar for you.

Paper attached

 

Thank you @mpjanic I will try to do the same next, take some of my favorite jazz and classic and remove my four major frequencies. Does it work for you? And what does it do to you?

 

I just found about this few days ago, so I can't really say what is the effect. When I listen to the music file I generated, there is some prolonged silence after, but of course after some time tinnitus comes back. I plan to modify all my music like this, as in the paper patients were under such treatment for 1 year, and after 6 months there was statistically significant improvement.

 

On the paper it says .. the frequency band of one octave width centered at the individual tinnitus frequency was removed from the music energy spectrum ... in my case main frequency is 7.2khzr one octave from 7200 hz is down 3600 and 14400 up so all frequencies from 5400 to 10800 are rem0ved wow this is A LOT ... imho .. music sounds very muffled without 5400+ frequencies ..

 

I don't think you need to go one octave width even though they say so, that may be too much, I just used arbitrarily +/-0.5kHz

 

And this was just to be sure my tinnitus frequency is within the gap, as I am not sure exactly what frequency it is.

 

It means a notch from half an octave below to half an octave above. It's the width of the notch that is 1 octave.

 

Sure which is always twice the frequency, by definition .. 200, 4o0, 800, 1600 etc ...

 

I don't understand what you mean. What you and I are saying are different things.
The notch you need to create around 1 kHz is not [ 0.5 kHz - 2 kHz ]. That would be a 2 octave wide notch. You need a 1 octave wide notch.

BTW, there are different schools of thought when it comes to the width of the notch that is necessary.

 

Yes would be from 750 to 1.5k .. trying to find papers how big the notch should be, if it is one octave it is crap, music sound pretty shitty without this frequencies totally cut of ...

 

No it would not: it's a logarithmic/exponential scale, so half an octave before 1 kHz is around 707 Hz and half an octave above 1 kHz is 1.414 kHz, for a notch of [ 0.707 kHz - 1.414 kHz ] which is a full octave width. If my math is correct, that is.

 

Sorry I was just approximating it is more a bit more complicated in music theory the half octave is a augmented 4th which is the six tone on the chromatic scale, which has usually the 11//8 or 64/45.. but sometimes it is calculated differently, Google tritonus, same goes depending which tuning you use a well temperate tuning has different frequencies for half octaves. it is not just simply math yes physically sure it is exponential but musically there is something like the diatonic comma etc and every running has different frequencies.. also the human brain can do something like adaptive perfect tuning AFAIK I am not not sure the ear reacts to physical correct math or musical tuning, have to research that.

Going back to the original topic.. tried acrn now for nine days, 3-4h a day interesting I can change my main frequency bit with it but not the noise level , I have three to four frequencies as tinnitus

 

When it comes to notching sound through a DSP, it's actually pure math (there is no ambiguity).
I appreciate that you have knowledge about scales and music theory, but the DSP filter is completely oblivious to that.

 

Hello guys I find that acoustic neuromodulation keeps my tinnitus low, does anyone know if this is permanent change? I mean if i kept listening to ACRN 2 hours daily, would my tinnitus stay in its low level all the way? Thank you.

 

I have no idea how this works in relation to the electric activity in our brain, but one thing is for sure, this neuromodulation does have an instant effect on T.

I guess the various frequencies are "playing with our brain" in order to make us lose track of our actual T.
I haven't tried using it for hours straight so far, but even listening to it for 30 minutes provide instant relief while listening.

There's definitely something going on here and it doesn't seem to work the same way as pure white/pink noises do. I don't know about you guys, but white/pink noises do not have any effect on me as I have too many frequencies going on at the same time.

Has somebody experienced "long-lasting" relief after listening for hours in a row ?

 

I found this on the net:

http://zyl.pestermom.com/projects/software/tinnituscr.html

Someone made a WAV generator based on some studies. I believe this is ARCN. The guy who developed this also has T.

@Steve is this good? Does it seem ok?

 

I can't seem to change every individual frequency on http://www.generalfuzz.net/acrn/

I can't hear anything above 13.800hz, but my T is around 12.500hz. So when I set it for 12.500hz then the last tone is at 17.400hz. In this case I would like the last tone to be one I can hear.

Can anyone else change the individual frequency from your browser?

 

Holy hell! This worked for my tinnitus. when the beeping stops my T is definitely changed, very silent

OMG I cant believe it....I have found something that can give me relief....I hope it don't stop working

How can some random beeps do that??

I now want ear maskers with this sound

 

I cant thank you enough @mpjanic!! you don't know what this means to me.....

 

I can't even hear this sound..?? i played it on very high volume and i don't hear anything.
Am i getting deaf?

 

Really? Remember the beeping only plays every 30 seconds, in between there is silence.

 

Not all speakers can reproduce these high frequencies correctly. It could be the speakers (and not your ears) at fault.

 

where is the website that you got the frequencies from? Is it good on iPods?

 

HI @JodieStephens,

Using headphones with an iPod and listening to neuromodulation tones maybe alright, but I don't recommend that you listen to music using headphones/earbuds etc even at low volume. Especially that your tinnitus is so intrusive.

Where do I get the Neuromodulation tones?

 

Options I know of:

1. Going with an audiologist and be setup with an ACRN (Acoustic Coordinated Reset Neuromodulation) device (the device itself is some kind of refurbished iPod). Cost: a few thousand dollars.
2. Open up a browser to generalfuzz's ACRN page. Cost: free

 

I live in Canada with universal healthcare, I wonder if the device would be paid for.

and generalfuzz's page doesn't play the sounds.
