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 ...
In this article, I will explore what humans can hear, including frequencies, hearing in noise, directional hearing, and how it compares to an animal’s hearing ability.
A cat can hear high-frequency sounds up to two octaves higher than a human. 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.
Animals with a greater ear distance can localize lower frequencies than humans can. For animals with a smaller ear distance the lowest localizable frequency is higher than for humans. If the ears are located at the side of the head, interaural level differences appear for higher frequencies and can be evaluated for localization tasks.
[3] [4] It is thought that the wild ancestors of cats and dogs evolved this higher hearing range in order to hear high-frequency sounds made by their preferred prey, small rodents. [3] 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 ...
Elephants are the terrestrial animal in which the production of infrasonic calls was first noted by M. Krishnan, [6] later discovered by Katy Payne. [7] The use of low frequency sounds to communicate over long distances may explain certain elephant behaviors that have previously puzzled observers.
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.
Reading books with repetitive words and rhyming books is especially helpful; it can help children hear the patterns in words that look and sound the same, Cross says.
