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.
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.)
(Greek: monos = one; phone = sound) A form of reproduction which records, transmits and reproduces the original sound along a single CHANNEL, regardless of the number of loudspeakers used. All components of the sound are combined or MIXed into one SIGNAL, including AMBIENCE and REVERBERATION, and therefore only the sense of depth may be simulated or reproduced.
The subjective impression of FREQUENCY, in the same sense that LOUDNESS is the subjective sense of the INTENSITY or AMPLITUDE of a sound. As such, pitch is a psychoacoustic variable, and the degree of sensitivity shown to it varies widely with people. Some individuals have a sense of remembered pitch, that is, a pitch once heard can be remembered and compared to others for some length of time; others have a sense of absolute pitch called PERFECT PITCH.
