Apparatus and methods for testing acoustic systems

摘要

Methods and apparatus are provided for testing an acoustic system having multiple transmitter elements and multiple receiver elements. A transmitter signal generated by a selected transmitter element is received. An echo electrical signal is generated in response to receipt of the transmitter signal. The echo electrical signal is transmitted to a selected receiver element. Information generated by the acoustic system with the selected receiver element in response to the echo signal is analyzed to diagnose operational characteristics of the selected receiver element.
