DownloadWhat is the primary goal of the CAOHC certification?
Omdraaien
The primary goal of the CAOHC certification is to ensure that professionals are adequately trained to conduct hearing conservation programs effectively and protect workers from occupational noise-induced hearing loss.
What does the acronym CAOHC stand for?
Omdraaien
CAOHC stands for the Council for Accreditation in Occupational Hearing Conservation.
Describe the role of an Occupational Hearing Conservationist (OHC).
Omdraaien
An Occupational Hearing Conservationist (OHC) is responsible for conducting hearing tests, educating employees about hearing protection, maintaining audiometric equipment, and ensuring compliance with hearing conservation program standards.
What is the significance of a baseline audiogram in hearing conservation?
Omdraaien
A baseline audiogram is significant because it serves as a reference point for comparing future audiograms to detect any changes in an individuals hearing ability over time, indicating potential noise-induced hearing loss.
How often should audiometric testing be conducted for employees exposed to high noise levels?
Omdraaien
Audiometric testing should be conducted annually for employees exposed to noise levels at or above the action level of 85 decibels averaged over 8 hours.
What is the action level for noise exposure in occupational settings?
Omdraaien
The action level for noise exposure in occupational settings is 85 decibels, averaged over an 8-hour workday.
Explain the term standard threshold shift (STS).
Omdraaien
A standard threshold shift (STS) is defined as a change in hearing threshold relative to the baseline audiogram of an average of 10 decibels or more at 2000, 3000, and 4000 Hz in either ear.
What is the purpose of hearing protection devices (HPDs)?
Omdraaien
The purpose of hearing protection devices (HPDs) is to reduce the level of noise exposure to the ear, thereby preventing noise-induced hearing loss in occupational settings.
