The cost of hearing loss in the workplace


Each year, approximately 22 million workers are exposed to hazardous, potentially damaging noise in the workplace.

For those who experience hearing loss as a result, the estimated workers’ compensation payout from employers is around $242 million.

Many workers conceal hearing problems in order to remain on-site. In that case, the risks of simply ignoring the problem go well beyond benefit payouts.

Significant hearing loss impairs an employee’s ability to understand speech, hear warning signals, and notice audio alarms. In most workplaces where hazards could occur (i.e.: a construction site or manufacturing plant), workers must effectively communicate with one another.

If someone misses a verbal cue, such as a safety manager’s direct order, then serious accidents may occur.


hearing conservation

A hearing conservation program must be implemented at, or above, a TWA of 85 dBA, as per OSHA.

OSHA’s hearing safety plan


In order to protect workers from hearing loss, OSHA created and enforced Regulation 29CFR 1910.95

It states that employees exposed to sound levels at, or above, 85 decibels adjusted (dBA) for an 8-hour time-weight average must be provided with some means to mitigate their exposure to the hazard.

In other words, if an employee endures hazardous noise for a specific period of time, his/her employer must monitor that employee’s hearing, and offer ways to conserve and protect it.

The action-level dBA mandated by OSHA (85), produces the same level of sound as a roadway with busy traffic. Damage may occur if that level is sustained for more than eight hours.

For every five dBA above that level, the standard cuts the allowable exposure time in half.

Loud noise serves as the most known workplace hearing loss catalyst, and its effects do not end there.

Recently, OSHA published a fact sheet showing that exposure to high levels of noise can lead to Tinnitus, stress, anxiety, high blood pressure, gastrointestinal problems, and chronic fatigue.


Solvent, metal exposure and hearing loss


Excessive noise exposure stands at the forefront of industrial hearing loss, but evidence suggests that it’s not the only thing causing damage.

Hazards such as solvents and metals put an estimated 9 million workers at risk for hearing loss annually.

A study performed on Pittsburgh-based aluminum workers by the Yale University Department of Occupational and Environmental Medicine concluded that “exposure to organic solvent mixtures is a risk factor for high frequency hearing loss.” It also states that “industries with solvent-exposed workers should include such workers in hearing conservation programs.”

Additionally, a 2009 occupational health surveillance study showed that co-exposure to heavy metals and/or organic ototoxic chemicals  – chemicals that result in hearing loss – may exacerbate the effect of noise exposure. 

Essentially, for workers that encounter solvents and metals, the risk of hearing loss increases significantly in noisy environments.


Where to Start


Proper medical surveillance and record-keeping provided the necessary information in the above studies.

OSHA requires all industrial workplaces to create and implement hearing conservation plans. The administration also mandates that employers provide workers with a variety of personal protective equipment, and consistent audiometric testing performed by licensed professionals.

The results of the audiometric testing must be recorded in conjunction with the hearing conservation provisions of the OSHA noise standard (1910.95).
