Acoustic device and methods
At least one exemplary embodiment is directed to a communication device that includes a microphone configured to detect an acoustic signal from an acoustic environment, and a processor, configured to detect an acoustical dampening between the acoustic environment and the microphone, based on a change in a characteristic of the acoustic signal and, responsive to the acoustical dampening, apply a compensation filter to the acoustic signal to form a compensated acoustic signal that is reproduced. Other embodiments are disclosed.
1. A device comprising:
a first Ambient Sound Microphone (ASM), wherein the first ASM generates a first ASM signal;
a second ASM, wherein the second ASM generates a second ASM signal;
a first ear canal microphone (ECM), wherein the first ECM generates a ECM signal;
a speaker;
