A microphone may use boundary layer technology in concert with a concave reflector to produce improved sensitivity. The concave reflector may be arranged with respect to a boundary layer creating surface such that the sound waves are concentrated at the boundary layer creating surface. Thus, an intense compression layer is formed proximate to the boundary layer creating surface. A transducer may arranged in opposition to the boundary layer creating surface to convert the boundary layer energy into an electrical signal.
