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 range of dog hearing is approximately 40 Hz to 60,000 Hz, which means that dogs can detect sounds far beyond the upper limit of the human auditory spectrum.

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 different hearing ranges. For example, some dog breeds can perceive vibrations ...
Not all sounds are normally audible to all animals. Each species has a range of normal hearing for both amplitude and frequency. Many animals use sound to communicate with each other, and hearing in these species is particularly important for survival and reproduction.
The frequency of most dog whistles is within the range of 23 to 54 kHz, [5] so they are above the range of human hearing, although some are adjustable down into the audible range. To human ears, dog whistles only emit a quiet hissing sound. [ 6 ]
[18]: 249 Sometimes sound refers to only those vibrations with frequencies that are within the hearing range for humans [19] or sometimes it relates to a particular animal. Other species have different ranges of hearing. For example, dogs can perceive vibrations higher than 20 kHz.
The relationship of the spiral turns of the cochela and the length of the basilar membrane to the range of audible frequencies in ground dwelling animals. Journal of the Acoustic Society of America 77:1091-1101; EA Lipman and JR Grassi. 1942.
[11] [12] [13] It is postulated that birds might use the detection of naturally occurring infrasound for long-range directional cues from distant landmarks, or for weather detection. [14] Since hearing tests at infrasonic frequencies have been conducted on a small number of bird species, the true diversity of this ability among birds is unknown ...
