Abstract

An earpiece (100) and acoustic management module for in-ear canal suppression control are provided. A method for suppressing signals for a conference call, a vehicle, and a general communication event is also provided. The earpiece can include an Ambient Sound Microphone (111) to capture ambient sound, an Ear Canal Receiver (125) to deliver audio content to an ear canal, an Ear Canal Microphone (123) configured to capture internal sound, and a processor (121). The processor can generate a voice activity level (622) and suppress an echo, spoken voice, and media content in the electronic internal signal, and mix an electronic ambient signal with an electronic internal signal in a ratio dependent on the voice activity level and a background noise level to produce a mixed signal (323) that is delivered to the ear canal (131).
