0 dB HL - CORRECT ANSWER: the average threshold for people with normal hearing.
0 to 25 dB - CORRECT ANSWER: intensity range considered normal hearing.
1 or 2 - CORRECT ANSWER: speech signals are often _____ or _____ syllable words
25 or 30 dB - CORRECT ANSWER: a common starting point of intensity (in dB) for air conduction testing.
26 to 40 dB - CORRECT ANSWER: intensity range considered mild hearing loss.
41 to 55 dB - CORRECT ANSWER: intensity range considered moderate hearing loss.
56 to 70 dB - CORRECT ANSWER: intensity range considered moderately severe
hearing loss.
71 to 89 dB - CORRECT ANSWER: intensity range considered severe hearing loss.
90 dB and above - CORRECT ANSWER: intensity range considered profound hearing
loss.
99% - CORRECT ANSWER: percent of normal hearing people with thresholds of 15 dB
or better.
250 to 8000 Hz - CORRECT ANSWER: the range of audiometric frequencies used in
conventional hearing testing.
500, 1000, 2000, and 4000 Hz - CORRECT ANSWER: frequencies used in bone
conduction testing.
500, 1000, and 2000 Hz - CORRECT ANSWER: the 3 frequencies whose thresholds
are used to determine pure tone average.
1000 Hz - CORRECT ANSWER: the starting point of frequency (in Hz) for air
conduction testing.
4000 Hz - CORRECT ANSWER: bone conduction testing does not exceed this level of
frequency.

acoustic signal - CORRECT ANSWER: a specific type of sound using in hearing testing; a type of signal.
air conduction - CORRECT ANSWER: hearing testing involving earphones.
air-bone gap - CORRECT ANSWER: the difference in dB between air conduction and
bone hearing thresholds of 10 dB or more; indicates that air conduction thresholds are poorer than bone conduction thresholds at the same frequency in the same ear.
around 0-110 dB HL - CORRECT ANSWER: the range of intensity levels used in
hearing testing.
ascending technique - CORRECT ANSWER: technique used in hearing testing that
begins at a level below a person's likely hearing threshold, with presentation of stimulus sounds at progressively higher levels.
asymmetrical hearing loss - CORRECT ANSWER: when there are different audiograms
for the left and the right ears, hearing loss is said to be this.
audiogram - CORRECT ANSWER: a graphic summary of the results of a hearing test.
audiometer - CORRECT ANSWER: electronic device that allows an audiologist to
choose a specific type of sound and present that sound to a patient at different intensity levels.
automated audiometry - CORRECT ANSWER: type of audiometry that is more cost
effective and efficient when the # of people needing to be tested is high an the likelihood of hearing loss is low.
automated audiometry - CORRECT ANSWER: type of audiometry that minimizes
operator error, but requires cooperation and understanding from the patient, so it cannot be used for infants.
automated audiometry - CORRECT ANSWER: type of audiometry that offers the only
feasible testing option in an industrial setting where a large # of people at risk for noise- induced hearing loss are required to undergo hearing screening (ie. the military).
better hearing ear - CORRECT ANSWER: the ear tested first during air conduction
testing.
Bone - CORRECT ANSWER: on an audiometer, this represents a bone oscillator.
bone oscillator - CORRECT ANSWER: a small box-like device consisting of electronic circuitry encased in plastic, used to present sounds (vibrations) to the skull in bone conduction auditory assessment.
