CAOHC Training
CAOHC's primary mission is to: - ANS-Educate, inform, and guide industry and those serving
industry on successful implementation of occupational HCP's to prevent occupational hearing
loss.
CAOHC recertification: - ANS-Is required every 5 years
The sector with the highest incidence of occupational hearing loss: - ANS-Manufacturing
Auditory effects of noise exposure include noise-induced hearing loss, hyperacusis and? -
ANS-Tinnitus
Noise-induced hearing loss typically occurs initially at? - ANS-4000 Hz
Early signs/symptoms of a noise-induced hearing loss include tinnitus, difficulty understanding in
background noise, and? - ANS-Reliance on visual cues
Type of hearing loss that results from cerumen impaction: - ANS-Conductive
Hearing loss due to aging is called: - ANS-Presbycusis
Part of ear damaged by hazardous noise exposure: - ANS-Organ of corti (cochlea)
According to the decibel doubling rule, when you add together two identical sources of
loudness, you increase the loudness by how many dB? - ANS-3 dB
The _________ weighting network resembles how the human ear responds to sound and is
required by OSHA to be used to determine risk and enroll employees in a HCP - ANS-A dBA
Steady-state or continuous noise, such as a generator, has a duration of: - ANS-1 second or
longer
Instrument that captures noise levels at a point in time: - ANS-Sound level meter
When employees are mobile or have varying exposures over a workday, the recommended
instrument for noise measurement is? - ANS-Dosimeter
OSHA recommends a minimum of a type _____ microphone for noise measurement equipment
- ANS-2
, The _______ is the HCP team professional most qualified to conduct noise measurements
based on their education: - ANS-Industrial Hygienist
The ______ is the HCP team professional most qualified to recommend engineering controls: -
ANS-Acoustical/noise control engineer
Noise can be controlled at the _____, _____, or ______ - ANS-Source, path, receiver
The following is the most effective way of delivering training/education: - ANS-One on One
The following element of a HCP, that is not included in the OSHA Noise Amendment, but makes
it a model program: - ANS-Analysis of program effectivemenss
The frequencies that are utilized to determine an OSHA STS are: - ANS-2000, 3000 and 4000
Hz
The amount of average shift from baseline needed for something to be considered an OSHA
STS: - ANS-10 dB
This amount of hearing loss at 2000, 3000, and 4000 Hz on the current audiogram (if also a shift
from baseline) may make it an OSHA Recordable STS: - ANS-25 dB or worse when
AVERAGED across above listed frequencies
Hearing threshold levels are recorded on an: - ANS-audiogram
The most fragile part of the audiometer is (are) the: - ANS-Headphones
Hearing protection must bring employee's exposure level to _____ dBA, and if they have a
confirmed STS, must bring it to _____ dBA: - ANS-90 & 85
The Noise Reduction Rating (NPR) is: - ANS-Derived in a laboratory setting
Dual protection provides an additional _____dB of attenuation added to the derated NRR of the
hearing protector with the highest NRR: - ANS-5
Advantages of noise muffs are that they are easy to fit, easy to monitor and are _____ -
ANS-Consistent attenuation
Advantages of formable earplugs are that they are compatible with personal protective
equipment, comfortable, and _____ - ANS-inexpensive
Advantages of pre-molded earplugs are that they are inexpensive, compatible with personal
protective equipment, and ______ - ANS-Ideal for dirty environments
