Disclosed, in general, are devices that provide a substantially sound-tight chamber over a sound source while absorbing fields of sounds from the sound source. In general, the devices feature: an anechoic chamber that is configured to receive a sound source in a substantially sound-tight manner; and an anechoic channel that is in fluid communication with the ambient atmosphere. The anechoic chamber is adapted to capture air containing sound energy generated by the sound source, and distribute the air about an internal surface area on the inside of the chamber, wherein the internal surface area is sufficiently large to dampen or otherwise absorb the sound energy. Specifically, the secondary anechoic chamber collects air from in-between the first and second anechoic chambers around the perimeter of the mouth, in the low decibel environment away from the voice blast high decibel areas in front of the mouth. Voice air from speaking fills up the primary anechoic cup chamber and once the primary anechoic cup chamber is full of air, then the air is channeled to the secondary anechoic chamber and into the suppressor channel where the voice air will exit the telephone with as low of decibel energy left as possible. Additionally, the apparatus may feature a circuit board with a telephone cord female jack connection and a plurality of switches, wherein the telephone female jack mounted on the circuit board receives a quick release levered male jack connected to a wire from the telephone base set. |
