Abstract
Equipment includes a first interface intended to be connected to a sound reproduction device and at least one second interface intended to be connected to at least one microphone, an acoustic processing unit adapted for delivering an audio signal filtered by attenuation or suppression of a reference audio signal from an audio signal received via the second interface. In an initialisation phase, the equipment determines a propagation latency; configures a buffer with a reading-triggering threshold defined according to the determined propagation latency. In a nominal operating phase, the equipment transmits a third audio signal via the first interface, the third audio signal being the reference signal after passing through the buffer.
