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.
Any quantity or body is in a state of oscillation when its value or motion is continually changing so that it passes through maximum and minimum values or positions. When a system, body or quantity is set in PERIODIC motion or vibration, it is said to be in oscillation.
If a sound is a complex of many TONEs of various FREQUENCY, AMPLITUDE and PHASE, repeating together in a basic CYCLE of definite frequency, the fundamental is the lowest frequency of this complex and corresponds to the unique PITCH heard in such a COMPLEX TONE.
The use of reflected SOUND WAVEs for obtaining environmental information. Certain animals, such as the bat and the porpoise, emit pulses of extremely high frequency sound (up to 50 kHz for bats, and up to 170 kHz for porpoises and whales) in narrow, intense streams. The REFLECTION, or ECHO, of these sounds supplies information regarding the nature and location of objects in the environment. When an emission of varying frequency is used, such as with bats, the echoes, travelling varying distances to the ear, are heard as different frequencies in each ear, thus supplying directional information.
