Abstract
A sound suppressor for a microphone on a low-power transmitter-receiver, sometimes called a citizens band radio. The sound suppressor is made up of a disc of paper-towel-like material and a disc of aluminum foil of like size sandwiched between two annular sheets of aluminum foil with central apertures so that the paper-towel-like disc is exposed from one side and aluminum foil from the other side. The suppressor is supported in front of a microphone so that the sound waves from a person's voice strike the disc. The several discs are held together around the outer periphery of the round discs by pressure-sensitive adhesive.
