Industrial Hearing Screening

Hearing damage is a real and unfortunate effect of long-term exposure to loud noise. Noise is a hazard of industrial workers and workers of any occupation who are repeatedly exposed to loud noises. This may include those who work in factories or on construction sites, firefighters, farmers, musicians and airport personnel.

Noise-induced hearing loss is fully preventable when the right precautions are taken from the start. Regular hearing tests to evaluate any early signs of hearing loss, as well as everyday preventative measures such as the use of ear plugs, go a long way toward preventing permanent hearing loss.

Industrial hearing test requirements

Organizations such as the Occupational Safety and Health Administration (OSHA) have enacted requirements and procedures for hearing conservation in an effort to standardize hearing safety practices and reduce the incidence of preventable hearing damage. Some states, as well as the Department of Defense, have their own guidelines.

In most cases, OSHA requires that employees who are exposed to a time weighted average (TWA) of 85 dBA be part of a hearing conservation program which includes hearing testing and employee training. Industrial manufacturers are also required to report evaluation results. A summary of OSHA’s hearing conservation program can be found on their website here:

Industrial hearing conservation programs

Some companies choose to meet these requirements independently. However, most companies choose to contract with a hearing conservation company to conduct hearing evaluations, keep records and make sure they comply with all safety standards and meet safety goals.

Failure to test and/or report noise exposure levels and the impact on employees can cost companies thousands in legal fees and federal fines. Hiring a professional or company to make sure they are in complete compliance is worth it in the long run.

Hearing conservation companies usually have mobile hearing evaluation units available to travel and perform on-site hearing evaluation services. They are typically staffed by a hearing specialist and/or an Occupational Hearing Conservationist (OHC, also known as an Industrial Audiometric Technician).

OHC Technicians are certified by the Council of Accreditation in Occupational Hearing Conservation (CAOHC) and are supervised by a hearing specialist or physician. They are trained to conduct hearing conservation procedures including pure-tone air conduction hearing testing. Their training is very specific to occupational settings only and is not applicable in non-occupational practices.

Education and referrals

OHC Technicians are trained to detect possible indications of early hearing loss as well as provide training for employees. If a possible hearing problem is detected, the technician will refer the employee for further tests by an audiologist.  At Country Roads Audiology & Hearing Aid Center we will provide routine annual hearing screenings for employers as well as test individuals who have missed their workplace screening or who need further diagnostic testing.  We can also provide custom hearing protection for employees and training on proper use of hearing protection.
