Abstract

An interior rearview mirror assembly (101) for a vehicle includes a mirror housing (10S) adapted for attachment to the interior of the vehicle, the mirror housing (106) including a back surface (107) generally facing the front of the vehicle and an opening generally facing the rear of the vehicle. A mirror (108) is disposed in the opening of the mirror housing (106) where a first microphone assembly (108a), second microphone assembly (108b), and third microphones assembly (108c) are positioned in the mirror housing (106) along its rear, bottom, or top surface. The three microphone assemblies (108a, 108b 108c) are arranged in a substantially triangular configuration for reducing unwanted sound in the vehicle from at least one direction. The microphone assemblies may operate using a delay-and-sum beam-former (403,. 405) and digital signal processor (DSP) (407) for enhancing the directivity of the microphone array within the vehicle.
