The microphone housing (7) has at least one sound inlet opening (2) and an electroacoustic transducer mounted in the housing, preferably a directional transducer, for fixed installation, especially in a mounting unit, a bracket or the internal cladding of a motor vehicle. Each sound inlet opening lies slightly above the surface enclosing (8) the housing and near the laminar boundary layer of the surface.
