Audiology Midterm Exam Review
Questions And Answers
/. What two professions joined together to create the profession of audiology? - Answer-
Otologists and speech pathologists
/.What is certification - Answer-Not a legal requirement. ASHA members must hold the
Certificate of Clinical Competence. Its more continuing education.
/.What is licensure - Answer-An important form of consumer protection, without it you
can not perform clinical audiology services.
/.How are certification and licensure different? - Answer-Licensure is required for all
audiologists to have to practice, while certification is optional
/.Name several specialty areas of audiology - Answer-Medical audiology
Educational audiology
Pediatric audiology
Industrial audiology
dispensing/ rehabilitative audiology
/.What can the decibel be expressed with? - Answer-Intensity reference (IL) or sound
pressure reference (SPL)
/.Sound pressure level (SPL) - Answer-Softest sound a human is capable of hearing
/.Reference level for dB SPL: - Answer-00002 dynes/ cm2 (absolute threshold for a
normal human listener)
/.SLP USED WHEN - Answer-measuring sound in the environment
/.dB HL (hearing level) - Answer-The softest sound a human is capable of hearing at a
specific frequency (pitch)
Humans are most sensitive to sounds in the 1k to 4k range
Audiologists are usually interested in measuring human hearing from 250-8000 Hz
/.dB HL Reference point: - Answer-the lowest sound energy it would take to stimulate
the human ear at a given frequency
Audiometric zero (0 dB HL)
/.dB HL USED WHEN - Answer-to describe an individuals threshold when describing a
hearing test
, /.dB SL (sensation level) - Answer-Softest sound a specific person is capable of hearing
/.dB SL reference point - Answer-Threshold of a given individual (the number of
decibels ABOVE an individual's threshold is dB SL)
/.What is the lowest frequency within a complex wave - Answer-Fundamental frequency
/.What is the relationship between intensity and loudness - Answer-Intensity: physical
value
Loudness: perceptual value
/.What is the relationship between frequency and pitch - Answer-Frequency: physical
value
Pitch: perceptual value
/.Be able to list the central auditory pathways past the vestibulocochlear nerve -
Answer-Cochlear nucleus
Superior olivary complex (or nucleus)
Lateral lemniscus
Inferior colliculus
Medial geniculate body
Auditory cortex
/.Decussation - Answer-crossover points within the brain that unite symmetrical portions
(signals crossing over)
/.Commissure - Answer-nerve fiber bundles that unite similar structures on both sides of
the brain (ex. Corpus callosum)
/.Ipsilateral - Answer-on the same side
/.Contralateral - Answer-on the opposite side
/.Name differences between screening and assessment - Answer-Screening:
No intent to diagnose
Measure needs to be sensitive
Not necessarily done by a specialist
Assessment:
Diagnostic in nature- more complete
Measure needs to be specific
Performed by a certified professional in that area
IDENTIFICATION AND DIAGNOSIS
/.What are the two mechanisms of hearing - Answer-Air Conduction and Bone
Conduction
