A segment or sequence of segments of MAGNETIC TAPE which have been SPLICEd end-to-end to form a loop or circle. When played in this form, the taped sound is continuously repeated, as distinct from tape ECHO or tape FEEDBACK.
Any FREQUENCY in the audible RANGE, usually between 20 and 20,000 Hz, and often referring to the frequency of AUDIO signals. Also called the audio spectrum.
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.
The study of the relationship between physical SOUNDs and the brain's interpretation of them. Until recently, psychoacoustics has devoted more attention to the behaviour of the peripheral auditory system than to the details of cognitive processing.
