Abstract
A sonic or acoustic tool having a transmitter and a receiver and further having a receiver testing and calibration device is disclosed. Methods for testing and tuning acoustic receivers dynamically are also disclosed. The calibration device includes an acoustic signal generator in acoustic communication with a receiver or a plurality of receivers, where the generator generates an acoustic calibration signal or test signal which propagates to each receiver. The receiver response is monitored to determine receiver integrity and tune. Based on the response, the processing unit or units can adjust the receiver response or instruct tuning circuitry associated with the receiver to adjust the receiver response.
