Abstract
A microphone holder for surveillance work and adapted to support a microphone in a concealed position when the holder is taped to the upper torso of a surveillance agent and to avoid clothing rustle and bulges resulting from the normal wear of the holder. The holder is of a flexible rubber material capable of moving with the wearer to permit comfortable use and avoid detection by persons under surveillance. The holder has an upper surface of a generally convex shape and a lower surface which is nearly flat but slightly concave. The upper surface is provided with a recess for the retention of a small microphone that can be un-encased and recessed below the upper surface to avoid clothing rustle. Microphone leads are kept below the upper surface in a groove to further avoid a detectable impression through the clothing of a wearer. Recording means which may include transmitting means is typically located elsewhere on the wearer.
