cochlea
weber tuning fork test
tuning fork is placed on the midline of the skull, assesses bone conduction of sound
Rinne tuning fork test
tuning fork is placed alternately near the auditory canal and behind the ear on the mastoid bone
audiometry
evaluates hearing acuity and helps to establish the degree and severity of hearing loss
audiometer
electric device used to measure the sensitivity of hearing by delivering a series of acoustic tones that range from very low to very high frequencies
audiogram
graph where listener signals when the tone is percieved is loged
