Definition - What does Audiometric Testing mean?
Audiometric testing refers to a medical procedure that gauges hearing sensitivity based on ambient noise level parameters that fall at or above the range of 85 decibels averaged within an 8-hour shift or 8-hour time-weighted average cycle. In safety-sensitive industries, a hearing conservation program requires audiometric testing for individuals as a preventative measure against noise exposure levels exceeding the 85-decibel threshold, resulting in eventual hearing loss impairment.
SureHire explains Audiometric Testing
For audiometric testing, an audiologist places an individual inside a soundproof booth accompanied by a set of earphones delivering audible stimuli via different frequencies/pitches connecting an audiogram, or a graph, to provide biofeedback. Consistent audiometric testing can serve as a mainstay for determining whether individuals are candidates for gradual hearing loss and, depending on the severity of each case, prompting the requirement of hearing protection devices. Regular training and proper maintenance, coupled with routine follow-up procedures for using hearing protectors, bolstered by mandatory audiometric testing procedures, is beneficial in workplace environments where noise-induced hearing loss can become progressively worse. Employers must stay abreast of current laws and regulations surrounding audiometric testing, referencing guidelines in tandem with provincial/territorial authorities.
