Abstract:
1. An acoustic processing module having an input to receive an acoustic signal and having an output terminal to provide an analog output signal, comprising: a number of microphone sensors, each for generating a corresponding audio electrical signal in response to the acoustic signal; a signal processing circuit having inputs connected directly to the microphone sensors and configured to process the audio electrical signals according to one or more analog signal processing functions to generate the analog output signal at the output terminal of the module; and an integrated casing encapsulating the microphone sensors and the signal processing circuit together and configured to prevent external interference from affecting the audio electrical signals or any other electrical signals within the integrated casing, wherein the output terminal is configured to provide the analog output signal to an ECM-compatible input interface of an associated device, and to receive power from the ECM-compatible input interface.
