AUDIOLOGY MIDTERM EXAM REVIEW
QUESTIONS WITH 100% VERIFIED
ANSWERS
\.Audiologist - ANSWERS✔-Clinically trained and licensed to identify, diagnose and
treat persons with auditory and balance disorders and the prevention of
impairments
\.Audiology profession - ANSWERS✔-Concerned with diagnostic management and
intervention (re) habilitation of persons with hearing and/or vestibular disorders
through using an battery of standardize tests combining behavioral ("subjective")
and electrophysiological ("objective") methods.
\.Hearing - ANSWERS✔-Capacity to sense and perceive simple and complex
sounds
\.afferent - ANSWERS✔-Hearing is the ________ pathway for the development of
language and communication
\.Sensation - ANSWERS✔-Auditory Stimulus: sound waves
\.Perception - ANSWERS✔-Electrical impulses generate in the cochlea and sent to
the brain through auditory pathways
,\.What is needed for normal hearing? - ANSWERS✔-1. Adequate Stimulus
2. Conduction of stimulus to sensory organs of hearing
3. Sensory transduction of stimulus at organs of hearing
4. Neural transmission of the signal
5. Central auditory processing of the signal at the brain
\.Sound - ANSWERS✔-Created when objects vibrate, causing surrounding medium
to vibrate and create pressure changes
\.Pure Tone - ANSWERS✔-Simple sound in a sinusoidal wave with a single
frequency
\.Amplitude - ANSWERS✔-Loudness (sensitivity thresholds)
\.Frequency (Hz) - ANSWERS✔-Number of cycles per second; determines pitch
\.Complexity - ANSWERS✔-Timbre, Chime or Ringer
\.Sound Intensity - ANSWERS✔-Wave amplitude- physical stimulus that gives rise
to the perception of loudness
\.Loudness is a ___________ sensation. - ANSWERS✔-Physiological
, \.Decibels (dB) - ANSWERS✔-Used to measure sound intensity
\.dB Scale - ANSWERS✔-base 10 logarithmic unit, increase means a unit is 10
times as loud

hearing ear
