Aural Diversity describes the plurality of the sense of hearing, encompassing the whole of human and animal nature and extending to machine listening. [1] The Aural Diversity Infographic shows its scope, including: the many changes in so-called “normal” hearing that occur over a lifetime; the universal variations that affect everybody's hearing; the medically identifiable hearing ...
Logarithmic chart of the hearing ranges of some animals [1] [2] 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 ...
The average cloud weighs over one million pounds. Wearing a necktie could reduce blood flow to your brain by up to 7.5 percent. Animals can also be allergic to humans.
The human auditory system is sensitive to frequencies from about 20 Hz to a maximum of around 20,000 Hz, although the upper hearing limit decreases with age. Within this range, the human ear is most sensitive between 2 and 5 kHz, largely due to the resonance of the ear canal and the transfer function of the ossicles of the middle ear.
The plan view of the human cochlea (typical of all mammalian and most vertebrates) shows where specific frequencies occur along its length. The frequency is an approximately exponential function of the length of the cochlea within the Organ of Corti. In some species, such as bats and dolphins, the relationship is expanded in specific areas to ...
