Abstract: A microphone includes a base, a micro electro mechanical system (MEMS) device disposed on the base, and a front end processing apparatus disposed on the base and coupled to the MEMS device, the front end processing apparatus being configured to convert analog signals received from the MEMS device into digital signals. The microphone also includes a DSP apparatus, the DSP apparatus being a digital programmed device with a computer memory, the DSP apparatus configured to process the digital signals received from the front end processing apparatus. The MEMS device, the front end processing apparatus, and DSP apparatus are enclosed within a single microphone enclosure or assembly. During operation the DSP apparatus generates DSP noise. The DSP apparatus includes a noise reduction structure that substantially prevents the DSP noise from reaching or interfering with the operation of the MEMS device or the front end processing apparatus.
