Noise-related hearing loss is preventable
Hazardous occupational noise can damage hearing. NIOSH states that occupational hearing loss is permanent but preventable, and recommends controlling noise exposure as the primary preventive approach.
Audiometry is one part of prevention
A hearing conservation approach includes exposure assessment, engineering or administrative controls, appropriate hearing protection, worker education and audiometric monitoring when indicated.
Compare results over time
Baseline and periodic audiograms are useful because change may matter more than a single isolated result. NIOSH surveillance programs use hearing data and exposure information to identify high-risk groups and evaluate prevention.
An abnormal result should not be filed and forgotten
A significant change should prompt appropriate clinical interpretation and, where relevant, review of exposure and existing controls. The objective is to prevent further damage.
