Patent ID: 7121142

Claim:
An acoustic measurement installation, characterized in that it comprises: acoustic measurement instrumentation ( 3 ) comprising in particular an acoustic measurement antenna ( 4 ) fitted with at least one microphone ( 5 ); a positioning system ( 11 ) for positioning the antenna ( 4 ) by ultrasound, the positioning system comprising: at least one ultrasound emitter ( 12 ) mounted on the antenna at a known distance relative to the microphone; and an ultrasound receiver base ( 14 ) for receiving the signals emitted by each emitter and adapted to determine the position of each emitter in three dimensions; and a control unit ( 16 ) for controlling the positioning system ( 11 ) for positioning the antenna ( 4 ) and the acoustic measurement instrumentation ( 3 ), the control system being adapted during a first stage to cause each emitter ( 12 ) to emit in succession in order to determine the position of the antenna in three dimensions, and during a second stage to cause the microphones ( 5 ) to perform acquisition in order to implement acoustic measurement using the measurement instrumentation.
