Onsite Hearing Testing

With 20+ years in the hearing health industry BaseLine Industrial Hearing has experienced licensed industrial audiometric technicians, to assist your worksite with your hearing conservation program needs.

WorkSafe BC Regulation 7.8

states that all noise exposed workers in BC must have a hearing test by an authorized provider within 6 months of employment and every year after the initial test.

BaseLine is authorized to conduct industrial hearing tests under the British Columbia Occupational Health and Safety Regulation. Our mobile unit is equipped with 2 soundbooths and state of the art equipment available to come to your worksite and conduct tests efficiently to minimize impact on your production needs.

Testing cards are given to each employee and they are counselled on the results and hearing protection requirements. Results will be added to the WorkSafeBC Hearing Test Submission system.

About Hearing Tests

Hearing tests measure an individual’s ability to hear sounds at different pitches and intensities. Hearing loss is common on worksites where impact noise and excessive noise exposure exists. Unfortunately, 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. Detection of hearing loss can be accomplished through baseline and periodic audiometric testing.

If your workers are exposed to noise greater than 85 dBA Lex (a full shift averaged exposure), you must provide them with all elements of the hearing loss prevention program, including annual hearing testing.

Annual hearing tests provide important information about the effectiveness of an employer’s hearing conservation program. If workers show early signs of noise induced hearing loss, employers can make changes to their noise control and hearing conservation program to prevent further hearing loss.

Industrial Hearing FAQ

Who requires an annual hearing test?
Workers who are exposed to 85dBA or greater averaged over an 8 hour shift.
As an employer, what are my responsibilities?
• To provide annual hearing tests for workers exposed to 85dBA or greater averaged over an 8 hour shift.
• To provide hearing protection when it’s not practicable to reduce noise levels.
• To review the noise control and hearing conservation program annually to ensure its effectiveness.
• To post warning signs in any work area where noise levels exceed 85dBA averaged over an 8 hour shift and 140dBC at peak sound levels.
• To ensure hearing tests are administered by authorized persons.
• To provide instructions on hearing protection devices and how to use them.
As an employee, what are my responsibilities?
• To wear proper fitting hearing protection in noise hazard areas and in accordance with instructions provided by the employer.
• To show up for annual hearing tests when scheduled.
How do I know if the noise level I’m exposed to is too loud?
• Rule of thumb is if you have to raise your voice to be understood by someone at arm’s length away, then it’s too loud. You may refer to “How Loud Is It?” to determine your average LEX level.
• Have an occupational noise survey completed.
Why do we have annual hearing testing?
These annual exams give us the ability to educate the worker on change that has occurred over the past year, review the importance of wearing properly fitted hearing protection and answer any questions they may have. Please refer to Testing Your Hearing How & Why for further information.
What is Tinnitus?
Tinnitus is the name given to ringing, clicking, hissing, buzzing, roaring or other noises in the ears.

Hearing Protection

Health & Safety Regulation 7.7 specifies hearing protection devices must be provided in accordance with the CSA Standard.

In order to be able to compare volume in different situations, noise levels are expressed in decibels (dB). Note that an increase of 3 dB is perceived as a doubling of the volume level. The sound level in a room can be roughly estimated by how well we can understand people speaking.

The impact of noise on body and soul

It is not only our hearing that suffers from noise. Even low noise levels can trigger the release of stress hormones, leading to increased blood pressure. This in turn can lead to aggressive behavior and tensions in interactions with other people, as well as an increased risk of stroke, heart attack and tinnitus. Unwanted sources of noise also prevent relaxation, recovery and sleep and impair concentration and performance.

In conditions where noise is persistent or excessive, such as in construction and industrial environments, those who fail to properly protect their ears run a much higher risk of irreversible hearing loss.

Our trained technicians can assist your workers to find the best solution for their hearing protection needs.

Occupational Noise Survey

OCCUPATIONAL NOISE SURVEYS

BaseLine Industrial Hearing Testing can perform an occupational noise survey for your workplace. A full summary is completed with our calibrated, integrated sound level meter and dosimeter.

Employers in BC are responsible for knowing which workers are overexposed to noise. The Occupational Health and Safety Regulation sets exposure limits for noise at 85 dBA (Lex) and a peak noise level of 140 dBC. When workers are or may be exposed to noise above 82 dBA Lex employers must measure the noise exposure unless an exemption applies (see page 7 of WorkSafe BC Publication “Sound Advice”). How loud is 82 dBA? If you have to raise your voice in your workplace to carry on a conversation, then the noise level is likely over 82 dBA. Workplace noise measurements:

  • Identifies significant sources of noise in the workplace and helps prioritize them for noise control measures.
  • Determines noise exposures of workers and identifies workers who require hearing protection, hearing testing, education, and training.
  • Determines workplace areas that should be posted as hazardous noise.

When noise exceeds regulated limits, employers must have an effective noise control and hearing loss prevention program. The regulated limit set by the WorkSafeBC for noise exposure in B.C. is 85 decibels (dBA) for an eight-hour period, or an equivalent noise exposure of one Pascal-squared hour (Pa2h). For impact noises (for example, pile driving or hammering), a 140-dBC peak sound level cannot be exceeded. The goal of a hearing loss prevention program is to reduce the noise exposure of workers to a safe level and prevent occupational hearing loss. By having a noise measurement taken at your place of business and work, you can make sure that the noise is within healthy limits for you and your employees. Hearing loss prevention programs must address:

• Noise measurement
• Education and training
• Engineered noise control
• Hearing protection
• Posting of noise hazard areas
• Hearing tests
• Annual program review

Respiratory Fit Testing

Stay safe & compliant by having us come ensure the respiratory equipment you’re using fits properly.
 
Prior to Fit Testing Please Ensure That All Employees:
  • Be Clean Shaven
  • Do Not Smoke 20 Minutes Prior to Test
  • Do Not Eat or Drink 20 Minutes Prior to Test (except water)
Masks that we can test:
  • Medical N-95 respirators
  • Industrial N-95 respirators
  • Full face respirators
  • Half masks

Important Information on Facial Hair and Respirators

When wearing a respirator that requires a seal with your face, you must be clean shaven where the respirator seals with your face. This helps to make sure your respirator can protect you from breathing contaminants. Please ensure that you are clean shaven prior to the fit test.
