It's possible to create your own MP3 files, if you want to give it a try. I've been doing this myself. It's sort involved, as you will see. Here's what you do...
1. Download a sound generator, such as the one from NCH software (
http://www.nch.com)
2. Assuming you have been to an audiologist and have an audiogram, your tinnitus frequency will be indicated where you have hearing loss. I have hearing loss my right ear at 4k and 8k. My tinnitus is at 4k.
3. The NCH tone generator plays continuous tones. Adjust the volume so that it's soft. Try to match the pitch with your tinnitus tone. Mine is about 4026 Hz.
4. Try to match the quality your tinnitus using the sine wave, square wave, or saw-tooth wave feature.
5. Save the tone file.
6. If you have more than one tone, add more tones. Save it.
OK, now you've got a simple tone. The next thing, you need to make it "patterned", to make it more cognitively interesting. That's the point of this research paper.
On the NCH tone generator application, there is a button "Edit tone". This sends the simple tone to the NCH sound editor called the "WavePad" editor.
1. In WavePad, you will see your simple tone, which plays for 1 minute.
2. There is a menu for special effects. Try the tremelo effect. This will produce a sound a patterned sound that is patterned - more interesting that a sine wave, so to speak. Try "wah-wah", etc.
The NCH generators are inexpensive. You will need to purchase these to make an MP3 file, unless you have a digital recorder (which I do).
There is also Tinnitus Tamer, which has less control, but the "sweep" feature is cool. If you go with Tinnitus Tamer, it's basically the same exercise: Try to make a sound that is very close to your tinnitus pitch, but make it "patterned" (i.e. more interesting), by using the sweep feature or the noise feature.
As I said, these are my experiments. I may break down and get Soundcure. The fact that these people have gone through all this research and testing would give me confidence, rather than Jerry-rigging an MP3 file. But, what the heck, the paper mentions that people can make their own MP3 files like I'm doing!
Karen -
I'm sure that your audiologist can order Soundcure if they don't have it yet. Remember, your audiologist is in the business of selling hearing aids and tinnitus maskers!
