Hearing range describes the frequency range that can be heard by humans or other animals, though it can also refer to the range of levels. The human range is commonly given as 20 to 20,000 Hz, although there is considerable variation between individuals, especially at high frequencies, and a gradual loss of sensitivity to higher frequencies ...
The frequency of baleen whale sounds can range from 10 Hz to 31 kHz, [27] and that of elephant calls from 15 Hz to 35 Hz. Both can be extremely loud (around 117 dB ), allowing communication for many kilometres, with a possible maximum range of around 10 km (6 mi) for elephants, [ 28 ] and potentially hundreds or thousands of kilometers for some ...
Higher pitches have higher frequency, and lower pitches are lower frequency. The frequencies an ear can hear are limited to a specific range of frequencies. The audible frequency range for humans is typically given as being between about 20 Hz and 20,000 Hz (20 kHz), though the high frequency limit usually reduces with age. Other species have ...
Ultrasound is sound with frequencies greater than 20 kilohertz. [1] This frequency is the approximate upper audible limit of human hearing in healthy young adults. The physical principles of acoustic waves apply to any frequency range, including ultrasound. Ultrasonic devices operate with frequencies from 20 kHz up to several gigahertz.
It is approximately the quietest sound a young human with undamaged hearing can detect at 1 kHz. [4] The threshold of hearing is frequency -dependent and it has been shown that the ear's sensitivity is best at frequencies between 2 kHz and 5 kHz, [ 5 ] where the threshold reaches as low as −9 dB SPL.
The wavelength of a sound is the distance between any two consecutive matching points on the waveform. The audible frequency range for young humans is about 20 Hz to 20 kHz. Hearing of higher frequencies decreases with age, limiting to about 16 kHz for adults, and even down to 3 kHz for elders. [citation needed]
