For a serious study it would be necessary to control many details. But if
you are just interested in a preliminary personal test, you might do
something like the following.

1) Take a piece of music that you like to hear. More importantly, take a
piece of which you know that it can occasionally increase the subjective
level of your tinnitus.

2) Transcode this piece into mp3, and also into wma (wma has an even
stronger and better data reduction that mp3).

3) Now wait for an occasion when your selected piece, in the original
version, increases your tinnitus. After that, switch off the original and
switch on the mp3 or wma version. Compare the effects upon your tinnitus.

Good luck,

Martin
