APPARATUS AND METHOD FOR AUTOMATICALLY RECOGNISING AN ACOUSTIC SIGNAL IN ORDER TO DETECT A TYPE OF ACOUSTIC MEASUREMENT APPLIED TO A BUILDING

摘要

The invention relates to a method for automatically recognising an acoustic signal in order to detect a type of acoustic measurement of a building. The method consists of: controlling a noise source placed in the environment of the building in order to emit a random or pseudo-random signal or a normalised impact machine placed on a floor of the building in order to emit a normalised impact noise; acquiring the acoustic signal that results in response using the sound-level meter; performing frequency band analysis on the acquired acoustic signal, applying detection threshold criteria for various types of building acoustics measurements in order to deduce therefrom the type of building acoustics measurement performed; and displaying the type of building acoustics measurement performed.
