Timbre or tone QUALITY is determined by the behaviour in time of the FREQUENCY content or SPECTRUM of a sound, including its TRANSIENTs which are extremely important for the identification of timbre.
For any PERIODIC wave the wavelength is the distance from a given point in the wave to the corresponding point in the next cycle of the wave, frequently represented by the Greek letter lambda. It may also be thought of as the distance the sound travels in one CYCLE or PERIOD.
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.)
(German: artificial head). A STEREOPHONIC recording system developed in Germany which employs an artificial head sitting on a resonator similar to a chest cavity. The recording MICROPHONEs are situated within the head, inside an anatomically correct ear canal, at the point where the human eardrum is located. Artificial PINNAE are carefully designed for accurate reflection of the incoming sound in order to achieve the good front-back and height-depth perspective for which the technique is noted.
