Abstract
Described herein is a method and apparatus for testing transducers either as single devices or in phased arrays. The apparatus includes a device which is housed in a casing (12) and comprises three polyurethane layers (15, 16, 17) each having different acoustic characteristics. A detector array (14) is located between two of the layers (15, 16). Means are also provided for clamping the device against a transducer to be tested to ensure good contact. Depending on the test mode of the transducer, either the transducer or the detector array are driven to provide signals which are detected by the other.
