Terms | Definitions |
|---|---|
 Pure tone | a sound in which particles of air vibrate at a single frequency |
| Hertz | the unit of measurement for the pitch of sounds |
| Decibel | the unit of measurement for the loudness of sounds |
| Bilateral conductive hearing loss | a conductive hearing loss in both ears |
| Unilateral conductive hearing loss | conductive hearing loss in only one ear |
| Cerumen impaction | overabundance of ear wax |
| Congenital atresia | partial or complete absence or blockage of the external auditory meatus |
| Otitis media | inflammation in the middle ear |
| Cholesteatoma | tumor that can occur in the middle ear |
| Otosclerosis | disease in which a bone in the ossicular chain because fixated in the oval window |
| Ossicular discontinuity | one of the tree ossicle bones breaks or somehow becomes disconnected from the other two |
| Temporary threshold shift | temporary hearing loss after being exposed to loud noise |
| Tinnitus | constant ringing, whistling, or roaring sound-inducedLoudness recruitment: abnormally rapid growth of loudness with an increase in intensity |
| Presbycusis | sensorineural hearing loss resulting from the effect of aging |
| Meniere's disease | disease of the vestibular system that has a sensorineural loss as one of it's components |
| Acoustic neuroma | tumor that impedes the functioning of the auditory nerve by pressing on it |
| Acoustic neuritis | inflammation of the auditory nerve |
| Auditory agnosia | disorder of the CANS in which the person has difficulty separating figure from background noise |
| Units of experience | objects and events to which words refer |
| Brain abscesses | walled-off cavities containing dead or dying white blood cells |
| Cerebral arteriosclerosis | thickening of the walls of cerebral arteries resulting in a slower rate of blood flow through them |
| Waveform | manner in which particles of air that are perceived as sound vibrate |
| Pure tone | a sound in which particles of air vibrate at a single frequency |
| Sine wave | the waveform for a pure tone |
| Hertz | the unit of measurement for the pitch of sounds. Higher the pitch, the larger the number |
| Decibel | unite of measurement for the loudness of sounds |
| Auricle | largely cartilaginous projecting portion of the outer ear |
| External auditory meatus | the part of the outer ear that is also referred to as the ear canal |
| Cilia | small hairs on the inner surface of the external auditory meatus |
| Ceruminous glands | the glands that secrete Cerumen |
| Cerumen | ear wax |
| Tympanic membrane | the eardrum |
| Malleus | first of the three tiny bones in the middle ear |
| Incus | second of the three tiny bones in the middle ear |
| Stapes | third of the three tiny bones in the middle ear |
| Ossicular chain | three tiny bones in the middle ear |
| Oval window | membrane that separates middle ear from the inner ear |
| Eustachian tube | a hollow structure that connects the middle ear to the back wall of the throat |
| Semicircular canals | the structures in the inner ear responsible for the detection of rotation |
| Vestibule | structure in the inner ear responsible for the detection of linear acceleration and gravity |
| Cochlea | structure in the inner ear responsible for hearing |
| Transduce | convert energy from one form into another |
| Auditory nerve | a branch of the cranial nerve that transmits electrochemical energy |
| Bilateral conductive hearing loss | a conductive hearing loss in both ears |
| Unilateral conductive hearing loss | a conductive hearing loss in only one ear |
| Cerumen impaction | an overabundance of ear wax |
| Congenital atresia | a partial or complete absence of blockage of the external auditory meatus |
| Otis media | inflammation in the middle ear that can cause a conductive hearing loss |
| Cholesteatoma | type of tumor that can occur in the middle ear and cause a conductive hearing loss |
| Otosclerosis | a disease in which the stapes become fixated in the oval window which causes a conductive hearing loss |
| Ossicular discontinuity | one of the three tiny bones that form the Ossicular chain in the middle ear breaks or somehow becomes disconnected from the other two |
| Temporary threshold shift | a temporary hearing loss after being exposed to loud noise that affects the functioning of the inner ear |
| Tinnitus | a constant or almost constant ringing, whistling, or roaring sound that appears to the person experiencing it to be located in one or both ears or somewhere in the head |
| Loudness recruitment | an abnormally rapid growth of loudness with an increase in intensity |
| Presbycusis | sensorineural hearing loss resulting directly or indirectly from the effect of the aging process on the inner ear |
| Meniere's disease | a disease of the vestibular system that has a sensorineural hearing loss as one of its components |
| Acoustic neuroma | a tumor that impedes the functioning of the auditory nerve by pressing on it |
| Acoustic neuritis | inflammation of the auditory nerve |
| Auditory agnosia | a disorder of the central auditory nervous system in which the person has difficulty separating figure from background noise |
| Units of experience | the objects and events to which words refer |
| Brain abscesses | walled-off cavities containing dead or dying white blood cells |
| Cerebral arteriosclerosis | a thickening of the walls of cerebral arteries resulting in a slower rate of blood through them |
| Functional hearing loss | a condition in which people do not respond appropriately to speech or other sound and there does not appear to be an abnormality lesion in their ears, auditory nerves, or CANS |
