ABSTRACT:
A sound system, for a band or the like, incorporates an anechoic enclosure which allows a performer to use the same desired speaker color under all performing conditions and which insulates the audience and other pick-up microphones from each sound-source's speaker and insulates the pickup microphone for each sound source from the ambient room sounds. According to the system, a sound source, such as a musical instrument, outputs a first sound signal which is amplified and fed to a speaker in an anechoic enclosure. In response to the speaker output, a microphone in the anechoic chamber outputs a second sound signal which is amplified and distributed to room speakers. In its exemplary embodiment, the anechoic enclosure comprises four laminated layers: an inner layer of rigid closed-cell foam surrounding a chamber; a layer of denser flexible, closed-cell foam; a second layer of rigid closed-cell foam; and an outer hard, rigid layer. The enclosure may be opened so that the speaker therein may be heard.
