SLHS 570 CAOHC Exam UPDATED ACTUAL Questions and CORRECT Answers
The noise-induced hearing loss "noise notch" typically
4000 Hz
occurs at:
Per OSHA, the Action Level is dBA TWA and the
85; 90
Permissible Exposure Limit is dBA TWA.
The OSHA Noise Standard and Hearing Conservation
29 CFR 1910.95
Amendment is:
Steady-state or continuous noise (sound) has a duration
1 second or longer
of:
An example of a(n) noise would be gunfire; an
impulse; impact
example of a(n) noise would be a nail gun.
The weighting network (or scale) that resembles how the
human ear responds to sound and required by OSHA to A
be used in HCPs to determine risk is:
The auditory effects of noise exposure include noise-in-
Tinnitus
duced hearing loss, hyperacusis, and:
Typical characteristics of a noise-induced hearing loss in-
clude a notch at 4000 Hz, variable susceptibility among Symmetrical and sensorineural
individuals, and:
A hearing loss should be referred for further au-
Asymmetrical/unilateral
diometric workup to rule out medical causes.
Effects from hazardous noise that cause a physical symp-
tom such as hypertension, or a psychological problem Non-auditory effects
such as depression are considered:
According to the decibel doubling rule, adding together
two identical noise sources of 100 dBA each will result in 103 dBA
a total of:
The relationship between and is what deter-
duration; intensity
mines the risk of noise-induced hearing loss.
