Patent ID: 8611560

Claim:
An acoustic device, comprising: a first Microphone (FM) configured to detect a first acoustic signal; a second Microphone (SM) configured to detect a second acoustic signal; a processor operative coupled to the FM and the SM, where the processor is configured to detect a spoken voice generated by a wearer of the acoustic device based on an analysis of the first acoustic signal and the second acoustic signal; and a voice operated control (VOX) configured to mix the first acoustic signal and the second acoustic signal to produce a mixed signal and control the production of the mixed signal based on one or more aspects of the spoken voice, wherein the VOX is configured to increase a first gain of one of the first acoustic signal and the second acoustic signal and decrease a second gain of a remaining one of the first acoustic signal and the second acoustic signal such that the mixed signal includes a combination of the first acoustic signal and the second acoustic signal, and wherein the analysis is at least one among a sound pressure level (SPL) comparison, a correlation, a coherence, a spectral difference and a ratio between the first acoustic signal and the second acoustic signal.
