Technical advances in these tests have allowed hearing screening for infants to become widespread.
Both hearing and touch are types of mechanosensation (Kung 2005).
Humans attach additional values to the sense of hearing when it helps them relate to others and to nature.
Hearing is the ability to perceive sound from a source outside the body through an environmental medium.
Hearing can be measured by behavioral tests using an audiometer.
The physiology of hearing in vertebrates is not yet fully understood.
Hearing impairment can inhibit not only learning to understand the spoken word, but also learning to speak and read.
Perceiving incorporeal things of an auditory nature would be considered spiritual hearing.
Hearing is a sense—that is, a mechanism or faculty by which a living organism receives information about its external or internal environment.
Hearing threshold and the ability to localize sound sources are reduced underwater, in which the speed of sound is faster than in air.
Hearing functions to detect the presence of sound, as well as to identify the location and type of sound, and its characteristics (whether it is getting louder or softer, for instance).
Both vertebrates and arthropods have a sense of hearing.
Synesthesia, or a mixing of senses, also relates to this phenomena, such as an individual hearing colors or seeing sounds.
Most evidence points to early identification of hearing impairment as key if a child with very insensitive hearing is to learn spoken language and proficient reading.
Many animals use sound in order to communicate with each other and hearing in these species is particularly important for survival and reproduction.
The ability to estimate just where a sound is coming from, sound localization, is dependent on hearing ability of each of the two ears, and the exact quality of the sound.
The cause of sound is vibratory movement from a disturbance, communicated to the hearing apparatus through an environmental medium, such as air.
Electrophysiological tests of hearing can provide accurate measurements of hearing thresholds even in unconscious subjects.
Each species has a range of normal hearing for both loudness (amplitude) and pitch (frequency).
Deafness, a lack of the sense of hearing, may exist from birth or be acquired after birth.
Much of the middle ear's function in hearing has to do with processing sound waves in air surrounding the body into the vibrations of fluid within the cochlea of the inner ear.
Human hearing is able to discriminate small differences in loudness (intensity) and pitch (frequency) over that large range of audible sound.
Underwater hearing is done by bone conduction, and localization of sound appears to depend on differences in amplitude detected by bone conduction (Shupak et al.
Hearing (or audition) is the sense of detecting sound, that is, receiving information about the environment from vibratory movement communicated through a medium such as air, water, or ground.
Tiger Senses - Hearing. ... For this reason, this sense is the most commonly and effectively used for hunting. Tigers are believed to be able to hear in the range of 0.2 kHz and 65 kHz, which is considerably different to the frequency at which humans hear. We have a hearing range of about 0.02 kHz and 20 kHz.
