KembaraXtra-Psychology - audibility range
Audibility range (also called the auditory spectrum) is the span of frequencies a person can hear as tones, bounded by the lowest and highest audible frequencies. For normal hearing it extends over more than 10 octaves, from roughly 16 Hz up to about 20,000 Hz, although the upper limit typically drops sharply with age. It connects to theories of pitch and tools such as the Galton whistle and concepts such as infrasound and ultrasound.
