An apparatus includes an acoustic sensor that receives a signal propagated by a well formation. The acoustic sensor includes a sensing component that receives the signal, a transmitter that transmits information based on the signal, and a receiver that receives the information. The transmitter and receiver are wirelessly coupled. The transmitter and receiver may be inductively coupled, capacitively coupled, or optically coupled, or the transmitter may transmit information using radio waves. The transmitter may be encapsulated in a polymer. The acoustic sensor may be part of a system including a downhole tool that detects subterranean conditions. The downhole tool may include a retaining member that retains the Acoustic sensor within an outer layer of the downhole tool. |
