Claim 11:
12. A method for sensing or transmitting an acoustic signal at least partially traveling through a borehole fluid within a wellbore, the method comprising:
conveying an acoustic device into the wellbore; the acoustic device comprising:
a compensation fluid,
an acoustic transducer at least partially disposed in the compensation fluid and configured to sense the acoustic signal,
a metallic cover that separates the compensation fluid from the borehole fluid and configured to deform in response to a pressure difference between the borehole fluid and the compensation fluid, wherein the pressure difference is created by the acoustic signal and a hydrostatic pressure in the borehole fluid, and
a processor in connection with the acoustic transducer; and

sending or receiving an electric signal with the processor to or from the acoustic transducer.
