ABSTRACT:
An acoustic sensor is disclosed that exhibits a wide linear bandwidth, provides a high signal-to-noise ratio, and that is rugged and relatively inexpensive. The sensor includes a piezoelectric polymeric tape transducer adhered to a portion of the inner surface of an acoustically transmissive shell. The transducer is coupled to a preamplifier within the shell that amplifies the transducer signal for transmission by a cable to a receiver. The preamplifier, transducer, and one end of the cable are encapsulated within the shell to support and protect the assembly.
