The rate of repetition of the CYCLEs of a PERIODIC quantity, such as a SOUND WAVE. Thus, frequency is the inverse of the PERIOD. More generally, frequency can be thought of as the rate of change of PHASE.
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.
