The act or power of perceiving sound; perception of sound; the faculty or sense by which sound is perceived; as, my hearing is good.

Extent within which sound may be heard; sound; earshot.

or audition : the subjective response to sound, including the entire mechanism of the outer, middle, and internal ear, and the nervous and cerebral processes which translate the sound into meaningful signals; the sense of sound perception from tiny hair fibers in the inner ear detecting the motion of a membrane which vibrates in response to changes in the pressure exerted by air molecules, within a frequency range (at best) of 20 to 20000 Hz, though this varies significantly with age, occupational hearing damage, and gender. Sound can also be detected as vibrations conducted through the body by tactition, including frequencies lower and higher than ear range. Human ear is not equally sensitive to all the frequencies of sound within the entire spectrum: middle ‘A‘and its higher harmonics (from 2 to 4 kHz) are at maximum human sensitivity. On sound pressure scale, the normal range of human hearing extends from about 0 dB (threshold of hearing) to about 140 dB; threshold of pain is about135 dB. heuristic : serving to indicate or point out; stimulating interest as a means of furthering investigation.

the range within which a voice can be heard; "the children were told to stay within earshot"

the act of hearing attentively; "you can learn a lot by just listening"; "they make good music--you should give them a hearing"

able to perceive sound

series of events in which sound waves in the air are converted to electrical signals and are then sent as nerve impulses to the brain where they are interpreted.

The subjective human response to sound.

long, thin setae (trichobothria) are located on legs; each of these setae are connected to a nerve ending; when the setae is bent by air currents the results are nerve impulses which function as sound receivers

Detection of sound.

Perceiving sounds.

The first stage in the listening process, in which sound waves are received by a communicator.

Hearing is one of the traditional five senses, and refers to the ability to detect sound. In humans and other vertebrates, hearing is performed primarily by the auditory system: sound is detected by the ear and transduced into nerve impulses that are perceived by the brain.
