An ultrasonic detector suitable for mounting in a position for surveying an area for a source of airborne ultrasound, which detector comprises a sensor for detecting an ultrasonic sound signal, characterised by a transducer configured to produce a broadband ultrasonic sound signal for reception by said sensor enabling said ultrasonic detector to perform a self-test.

Detector and methods of detecting

An ultrasonic detector suitable for mounting in a position for surveying an area for a source of airborne ultrasound, which detector comprises a sensor for detecting an ultrasonic sound signal, characterized by a transducer configured to produce a broadband ultrasonic sound signal for reception by said sensor enabling said ultrasonic detector to perform a self-test.

A compression assembly () forms an airborne sound sensor for detecting sound pressure level. The airborne sound sensor includes a piezo electric transducer () compressed against a top element () and a lower element () so as to compress the transducer () across a first face and a distal second sensing face.
