Definition - What does Periodic Audiometric Testing mean?Periodic audiometric testing is a type of audiometric testing that measures progressive hearing loss sensitivity levels following an initial (baseline) hearing threshold examination to compare differences in auditory changes on an annual cycle. The Standard Threshold Shift (STS) underlines hearing loss impairment with an average shift of 10 decibels (dB) at 2,000, 3,000, and 4,000 hertz, a normative range to isolate sound intensity.
SureHire explains Periodic Audiometric Testing
Noise-induced hearing loss is often a catalyst for periodic audiometric testing. After a baseline audiogram, periodic audiometric testing can help track any potential hearing decline. Field experts utilize a regulated benchmark called an A-weighted decibel scale, which features graduated units that measure frequencies (sound waves) based on decibel intensity variables aligned with periodic audiometric testing parameters.
Noise exposure at or above 85 dB is a safety hazard, carrying detrimental health implications that can lead to permanent hearing loss or a condition known as tinnitus. Periodic audiometric testing can be a critical tool to help offset the risk of noise-induced hearing loss.
