A TONE having more than a single FREQUENCY component. For instance, a tone consisting of a FUNDAMENTAL and OVERTONEs or HARMONICs, may be said to be complex.
Also called flanging or flangeing. An effect created by adding together two identical SIGNALs separated by a very short time delay (less than 25 ms, but strongest below 10 ms). These short delays are within the audio WAVELENGTH range, and the combination of the two signals affects the frequency SPECTRUM of the composite sound.
Literally, to hear with two ears. Opposite of MONAURAL HEARING. The fact that the ears are some distance apart allows the localization of sound by registering the slight differences in time, PHASE and INTENSITY of the sound striking each ear. Each of these parameters has a different area of effect, intensity being a major factor above 1500 Hz (see SOUND SHADOW), while PHASE DIFFERENCEs (which are equivalent to time differences) are used in localizing lower frequency sounds.
An adjective describing any process involving the transfer of a SIGNAL from acoustic to electrical form, or vice versa. Most commonly, TRANSDUCERs such as the MICROPHONE or LOUDSPEAKER are examples of this process.
