1

: the sense or act of hearing

Audition

2

: the number of complete wavelengths that pass a point in a given time (for example, per second)

Frequency

3

: a tone’s experiences highness or lowness; depends on frequency

Pitch

4

: the chamber between the eardrum and cochlea containing three tiny bones (hammer, anvil, and stirrup) that concentrate the vibrations of the eardrum on the cochlea’s oval widow

Middle ear

5

: a coiled, bony, fluid-filled tube in the inner ear; sound wave traveling through the cochlear fluid trigger nerve impulses

Cochlea

6

: the innermost part of the ear, containing the cochlea, semicircular canals, and vestibular sacs.

Inner ear

7

: hearing loss caused by damage to the cochlea’s receptors cells or to the auditory nerves; also called nerve deafness

Sensorineural hearing loss

8

: hearing loss caused by damage to the mechanical system that conducts sound waves to the cochlea

Conduction hearing loss

9

: a device for converting sound into electrical signals and stimulating the auditory nerve through electrodes threaded into the cochlea

Cochlear implant

10

: in hearing, the theory that links the pitch we hear with the place where he cochlea’s membrane is stimulated

Place theory

11

: in hearing, the theory that the rate of nerve impulses traveling up the auditory nerve matches the frequency of a tone, thus enabling us to sense its pitch

Frequency theory

12

: the theory that the spinal cord contains a neurological “gate” that blocks pain signals or allows them to pass on to the brain. The “gate” is opened by the activity of pain signals traveling up small nerve fibers and is closed by activity in large fibers or by information coming from the brain

Gate-control theory

13

: the system of body movement and position, including the sense of balance

Kinesthesia

14

: the sense of body movement and position, including the scene of balance

Vestibular sense

15

: the principle that one sense may influence another, as when the smell of food influence its taste

Sensory interaction

16

: in psychological science, the influence of bodily sensation, gestures, and other states on cognitive preferences and judgements

Embodied cognition
