Abstract
An acoustic processing module receives an acoustic signal, and outputs an analog output signal. Microphone sensors are provided for generating a corresponding electrical signal in response to the acoustic signal. A signal processing circuit is connected to the microphone sensors, and processes the electrical signals according to one or more analog signal processing functions to generate the analog output signal. An integrated casing encapsulates the microphone sensors and the analog processing circuit, and prevents external interference from affecting any electrical signals within the integrated casing.
