Anatomy
The anatomy of the human ear consists of the
outer, middle, and inner ear
In ___ hearing, AC and BC are normal and there is no air-bone gap
normal
Perceptual correlate of frequency
pitch
Interruption in the chain of bones -due to disease or fracture or abnormal elasticity of the TM
high compliance
Earphones utilize ___ conduction
air
What is responsible for hearing
cochlea
Mixed hearing loss could be caused by a disorder of the
inner and middle ear
Speech of sound through a transmitting medium
velocity
A measure used in audiology to assess the mobility (or compliance) of the eardrum (tympanic membrane) in response to changes in air pressure within the ear canal
static acoustic compliance
90-100%
Waxy oil produced by glands in the the ear canal that protect the ear from infection
cerumen
conductive
A unit of measurement of the intensity of a sound in acoustics and in audiometers
decibel
The first 10 to 15 milliseconds after the introduction of a signal and originated in the 8th cranial nerve and brain stem
ABR - auditory brain response
A VU meter is used to measure the ___ of an input source
intensity
The cochlea is a __-___ space
fluid-filled
In ___ HL, AC and BC are impaired due to an issue in the inner ear or hearing nerve
sensory/neural
The point in the cycle at which the vibrator is located at a given instant in time
phase
Electrical signals generated by the auditory system at various levels (from the cochlea to the cortex) in response to sound stimuli.
AEPs - auditory evoked potentials
The tympanic membrane vibrates most efficiently when the pressure on both sides is __
equal
tympanic membrane
Age-related hearing loss that develops gradually over time
presbycusis
Distance between any point on the sinusoidal wave and the same point on the cycle of the next wave
wavelength
Low-level sounds that are generated by the inner ear, specifically by the outer hair cells of the cochlea, in response to auditory stimulation or spontaneously without any external sound.
OAEs - otoacoustic emissions
Defined as the lowest level in dB at which a subject can barely detect the presence of speech and identify it as speech
