Why isn't there much interest about the "sound" of Mars?

There are several reasons. One is because the atmospheric pressure on Mars is about 0.03% of Earth; there really isn't very much stuff out there to listen to.

But the main reason is that there was no good reason to carry such an instrument. What could they possibly listen to that would provide useful scientific data? They are not going to be able to listen for the signs of life, they can't listen for geological data or atmospheric composition. They couldn't hope to get much back other than some generic wind sounds.
