Audiometric Testing

Hearing loss is common on work sites due to impact noise and excessive noise exposure. Hearing loss due to excessive noise exposure can be hard to detect, as the loss is gradual and is usually not recognized by the worker until their ability to communicate with others is affected.  Early detection of hearing loss can be accomplished through annual testing of your workforce.

Employers of workers who are noise-exposed are required to implement a hearing conservation program, which consists of...

  • Sound level monitoring
  • Baseline and periodic audiometric testing
  • Worker education
  • Referral to a hearing professional, if required
  • Medical surveillance
  • Provisioning of appropriate hearing protection

SureHire’s audiometric testing program helps employers comply with Occupational Health & Safety (OHS) legislation. We use standardized equipment and protocols across the country, and our testing is completed by certified technicians.  Our audiologist reviews results and completes follow-up with workers as required.

Our national network of audiometric testing facilities, as well as our mobile audiometric testing fleet, removes many of the logistical issues around testing. The network also allows for a seamless addition of audiometric testing to an employer’s pre-employment testing program to record a baseline value before the first day of work.

SureLink, our results database, notifies companies when an employee is due for a annual periodic audiometric test. Results comparisons are completed, allowing for the detection of any changes to hearing ability over time. In order to understand whether a worker’s hearing is being impaired as a result of job related activities, SureHire recommends performing baseline testing prior to employment, followed by periodic testing every 12 months.

Audiometric Testing Benefits:

  • Assists employers by defining a benchmark for hearing ability upon hire.
  • Provides identification of hearing loss and promotes early intervention by comparing yearly test results.
  • Provides a detailed explanation from an audiologist of abnormal test results to the worker and recommendations for follow-up actions.
  • Assists with the evaluation of your Noise Management Program during the annual review process.
“Occupational hearing loss is one of the leading causes of work-related disorders”. (Worksafe Alberta, January 2008)

We are the designated service provider for the Industrial Audiometric Testing Program (a.k.a. SureAudio) that is operated by CLR & ECAA.  For further information on this program, please contact your Account Representative.


What is the testing process?

The worker fills out a consent form and an audiometric history form detailing their hearing history, previous and current noise exposure, and any relevant medical conditions. Following test completion, all information is entered into SureHire’s centralized online results database. If the worker has previous audiometric testing records they will be automatically linked and a periodic comparison will be completed. 

Those with abnormal results will receive a letter containing follow-up recommendations from our audiologist once a thorough review has been completed.  

What does the machine do?

The Audiometer was designed primarily for use in determining hearing threshold levels in comparison with standard reference threshold levels. The Audiometer is a screening device that will allow the operator to screen employees for shifts in hearing acuity.The Audiometer is used to record the subject’s current threshold, which may be affected from day to day by noise exposure, colds, sinus infections, or other problems.

Can you use my audio results from my last appointment?

No. Due to OH&S regulations, previous test results cannot be recycled. For each new company that a worker is employed with, a baseline test must be completed within 6 months of employment. Results are not transferrable from one company to another.

Is an abnormal audio result a fail?

No. However, we will give you a referral number that you can call to get a certified professional to determine the cause of your abnormal results.

How long does this test take?

From start to finish, the test should be around 5-10 minutes

Are the tones loud?

An audiometry evaluation is a painless, noninvasive hearing test that measures a person’s ability to hear different sounds, pitches, or frequencies. A pure tone audiometry test measures the softest, or least audible, sound that a person can hear. During the test, you will wear earphones and hear a range of sounds directed to one ear at a time. The loudness of sound is measured in decibels (dB).

  • A whisper is about 20 dB
  • Loud music ranges 80-120 dB
  • A jet engine is about 180 dB.

The tone of sound is measured in frequencies (Hz). Low bass tones range 50-60 Hz, high-pitched tones range 10,000 Hz or higher. Normal hearing range is 250-8,000 Hz at 25 dB or lower

Can I wear my hearing aids during the test?

No. According to regulations, no accessories may be worn during the test that will amplify the tones being presented. Your test results must report your hearing thresholds without the use of hearing aids.

Will somebody be explaining the results of my audiometric test?

Yes. After the exam, a tester will write the results on an audio card that you will take with you. They will explain the results and answer any questions you may have. You will also receive an information pamphlet containing additional information about your test results, as well as SureHire’s contact information should you have any additional questions or concerns.
