The Ear Diagnostic Procedures Flashcards
Audiogram
Graphic record that illustrates the results of audiometry
Audiometer
Instrument to measure hearing
Audiometry
Test of hearing ability by determining the lowest and highest intensity (decibels) and frequencies (hertz) that
a person can distinguish. The patient may sit in a
sound-proof booth and receive sounds through earphones as the technician decreases the sound or lowers the tones
Decibel (dB)
Measures the intensity or loudness of a sound. Zero decibels is the quietest sound measured and 120 dB is the loudest sound commonly measured
Hertz (Hz)
Measurement of the frequency or pitch of sound. The lowest pitch on an audiogram is 250 Hz. The measurement can go as high as 8000 Hz, which is the highest pitch measured
Rinne and Weber Tuning-Fork Tests
Tests that assess both nerve and bone conduction of sound. The physician holds a tuning fork, an instrument that produces a constant pitch when it is struck, against or near the bones on the side of the head
Otoscope
Instrument to view inside the ear canal
Otoscopy
Examination of the ear canal, eardrum, and outer ear using an ‘otoscope.’
Tympanogram
Graphic record that illustrates the results of tympanometry
Tympanometer
Instrument used to measure the movement of the tympanic membrane
Tympanometry
Measurement of the movement of the tympanic membrane. Can indicate the presence of pressure in the middle ear
Falling Test
Test used to observe balance and equilibrium. The patient is observed balancing on one foot, then with one foot in front of the other, and then walking forward with eyes open. The same test is conducted with the patient’s eyes closed. Swaying and falling with the eyes closed can indicate an ear and equilibrium malfunction
