Abstract: A method and system for reducing the undesirable noise in a communication signal is provided. Designed specifically to address the problem of telephone communications where the desired speech signal is contaminated by background noise, this invention employs digital signal processing of the communication signal to selectively emphasize, buffer, amplify, and smooth the components of the signal, thereby enhancing the signal quality (signal to noise ratio) of the presented communication signal.

Abstract: A communication device and overmold adapted to minimize the feedback, acoustic coupling, and seismic vibration between a speaker and microphone in close proximity, as is typically found in hands-free headsets, is provided. This invention, through the use of specific structures absorbs unwanted noise and sound waves thereby improving the performance of the communication system as a whole. The complete system of this invention is provided in several embodiments, including an embodiment where the microphone is inserted within the overmold structure, an embodiment where the microphone is a boom microphone and an embodiment where the microphone is somewhat remote (a few inches) down from a miniaturized overmold and is provided with an ON/OFF switch.
