Method and apparatus for measuring the total, partial or directional acoustic power emitted by some source

摘要

A microphone or a hydrophone M is mounted so as to be displaced with respect to the sound source S between a first position P1 and a second position P2 and a phase reference signal emitter C is placed on the source S or in its immediate vicinity, the microphone M and the sensor C being simultaneously connected to a computer 5 which processes the signals received using appropriate methods, the apparatus allowing measurements which are less affected by high frequency sound not coming from the source S.
