Disclosed, in general, are devices that provide an air-tight chamber over a sound source while absorbing all fields of sounds from the sound source. In general, the devices feature: an anechoic chamber that is configured to receive a sound source in an air-tight manner; and an anechoic channel that is in fluid communication with the ambient atmosphere. Suitably, 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 sounds energy. Preferably, the air is directed from the anechoic chamber through an anechoic channel extending therefrom to the ambient to further dampen or absorb the sound energy. In one configuration, the outer wall of the apparatus is configured to reflect ambient sounds.
