Abstract: An acoustic measurement installation including acoustic measurement instrumentation, in particular an acoustic measurement antenna fitted with at least one microphone; a positioning system for positioning the antenna by ultrasound and including at least one ultrasound emitter mounted on the antenna at a known distance relative to the microphone and an ultrasound receiver base for receiving the signals emitted by each emitter and adapted to determine the position of each emitter; and a control unit for controlling the positioning system for positioning the antenna and the acoustic measurement instrumentation. The control system is adapted during a first stage to cause each emitter to emit in succession in order to determine the position of the antenna, and during a second stage to cause the microphones to perform acquisition in order to implement acoustic measurement using the measurement instrumentation.

Abstract: The acoustic measurement installation 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; 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, and during a second stage to cause the microphones (5) to perform acquisition in order to implement acoustic measurement using the measurement instrumentation.
