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 ...
An audio frequency or audible frequency (AF) is a periodic vibration whose frequency is audible to the average human. The SI unit of frequency is the hertz (Hz). It is the property of sound that most determines pitch. [1] The generally accepted standard hearing range for humans is 20 to 20,000 Hz.
We can define sound as our perception of air vibrations. Therefore, sound does not exist if we do not hear it. When a tree falls, the motion disturbs the air and sends off air waves. This physical phenomenon, which can be measured by instruments other than our ears, exists regardless of human perception (seeing or hearing) of it.
The absolute threshold of hearing (ATH), also known as the absolute hearing threshold or auditory threshold, is the minimum sound level of a pure tone that an average human ear with normal hearing can hear with no other sound present. The absolute threshold relates to the sound that can just be heard by the organism.
Zoomusicology (/ ˌ z oʊ ə m j uː z ɪ ˈ k ɒ l ə dʒ i /) is the study of the musical aspects of sound and communication as produced and perceived by animals. [1] It is a field of musicology and zoology, and is a type of zoosemiotics.

Ultrasonic hearing is a recognised auditory effect which allows humans to perceive sounds of a much higher frequency than would ordinarily be audible using the inner ear, usually by stimulation of the base of the cochlea through bone conduction. Normal human hearing is recognised as having an upper bound of 15–28 kHz, [1] depending on the person.
A cougar is shown attacking and dragging away a deer in a rare trail cam video of the predatory animal. Eli Schaefer shared video on Facebook on Jan. 7 of the attack, which he said happened Dec ...
