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 15.000 to 20,000 Hz, although there is considerable variation between individuals, especially at high ...
This physical phenomenon, which can be measured by instruments other than our ears, exists regardless of human perception (seeing or hearing) of it. Putting these lines of thought together, we can say that although the tree falling on the island sends off air waves, it does not produce sound if no human is within the distance where the air ...
Hearing loss is a partial or total inability to hear. [5] Hearing loss may be present at birth or acquired at any time afterwards. [6] [7] Hearing loss may occur in one or both ears. [2] In children, hearing problems can affect the ability to acquire spoken language, and in adults it can create difficulties with social interaction and at work. [8]
Human hearing spans from 20 Hz to 20,000 Hz. ... to the side, behind, or above. Humans are very good at locating sounds in front of us, usually within 1 degree of the source (the one except it ...
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.
Psychoacoustics is the branch of psychophysics involving the scientific study of the perception of sound by the human auditory system.It is the branch of science studying the psychological responses associated with sound including noise, speech, and music.

Selective hearing is not known to be a disorder of the physiological or psychological aspect. Under the World Health Organization (WHO), a hearing disorder happens when there is a complete loss of hearing in the ears. It means the loss of the ability to hear. Technically speaking, selective hearing is not "deafness" to a certain sound message ...
