Abstract
A triangular microphone assembly () for use in a vehicle accessory includes a mirror housing () adapted for attachment to the interior of the vehicle. A mirror is disposed in an opening of the mirror housing () and a plurality of virtual digital microphones () are arranged in a substantially triangular configuration in the mirror housing (). A digital signal processor (DSP) () is used for receiving signals from the plurality of digital microphones () such that the digital microphones exhibit directional characteristics for reducing undesirable noise in at least one direction by normalizing the phase of the received signals as a function of signal frequency.
