   There are no microphones of any kind on Mars at present.  (There was one   
   on the late lamented Mars Polar Lander...)   
      
   As for infrasound, my gut reaction is that between the inherent   
   difficulties of coupling a very-low-frequency oscillation to a small   
   instrument, and the problems added by the thin air, it would be quite   
   difficult to build a lightweight infrasound microphone for Mars.  But it's   
   not an area I'm familiar with.
