METHOD FOR LIVE PUBLIC ADDRESS, IN A HELMET, TAKING INTO ACCOUNT THE AUDITORY PERCEPTION CHARACTERISTICS OF THE LISTENER

摘要

The invention relates to a public address method for live broadcast, in a helmet (7), of an audio signal (8) conditioned from a plurality of raw audio channels (6), characterised in that it comprises: a pre-processing phase (100) comprising the operations that consist of: o taking into account characteristics of the auditory perception of the listener; o correcting each channel (6) as a function of the characteristics of the auditory perception of the listener; a mixing phase (400) comprising the production, from the channels (6) thus pre-processed, of a mixed audio signal (16); a post-processing phase (500) comprising the operations that consist of: o measuring (510) the sound level of a background noise; o correcting (520) the mixed audio signal (16) as a function of the sound level of the background noise; a phase (600) of reproducing, in the helmet (7), the conditioned audio signal (8) resulting from post-processing.
