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.
