Sorry, nothing listed in our inventory is for sale. We own and use it for a reason. If we do end up getting rid of something, it is probably because it has cursed us too many times, so you wouldn't want it anyway.

Although often employed interchangeably with ACOUSTICS, the term might better be restricted to the technology dealing with the practical applications of SOUND, as distinct from the pure science of acoustics. (It will be noted, however, that the contemporary acoustical engineer or acoustician is often mostly involved with the practical applications of sound.)
The device, successor to the MAGNETIC WIRE recorder, which since the 1940s (when it was called the sound mirror) has been the most commonly used means of storing and reproducing an AUDIO signal.
Sound at frequencies above the audible range, namely above 20 kHz, audible only to various non-human species. Because of its very short WAVELENGTH in the megahertz range, ultrasound is used as a safe alternative to X-ray photography in medical diagnosis. Ultrasound scanning is sometimes called sonography.
A term used in broadcasting and recording to indicate a spatial movement of a SIGNAL. A sound is panned when it is moved smoothly from one location (e.g. LOUDSPEAKER or CHANNEL) to another. This is accomplished by using various ATTENUATORs or POTENTIOMETERs, sometimes combined into a single unit called a pan-pot or panoramic divider in order to control the AMPLITUDE of the signal in each channel.
