Acoustic Sensor and Method
First Claim
1. A sensor apparatus comprising:
- a plurality of acoustic transducers, each being operative to produce a change in an electronic output signal in response to receipt of an acoustic signal; and
a plurality of processing circuitry, each being juxtaposed with a different, respective acoustic transducer such that a plurality of unitary bodies are formed;
each of the plurality of processing circuitry being configured to receive a first electronic output signal and a second electronic output signal produced by its respective acoustic transducer, and each processing circuitry being operative to shift a phase of the first electronic output signal and the second electronic output signal in relation to each other.

Abstract
The invention relates to a sensor apparatus (30) operable to receive and process acoustic signals. The sensor apparatus comprises at least one acoustic transducer (32) operative to produce a change in an electronic output signal in response to receipt of an acoustic signal by the acoustic transducer. The sensor apparatus also comprises processing circuitry (34) configured to receive a first electronic output signal and a second electronic output signal produced by the at least one acoustic transducer. The processing circuitry is operative to shift a phase of the first electronic output signal and the second electronic output signal in relation to each other. The acoustic transducer and the processing circuitry of the sensor apparatus are juxtaposed such that they form a unitary body.
