Noise induced hearing loss (NIHL) is one of the leading occupational diseases in the province of Quebec. NIHL is the second most frequent reported claims to the CNESST, moreover, it is the most costly occupational disease for the province of Quebec. As of 2010, each new case of NIHL cost 153 618$ and the total cost of NIHL was 667 million$ for the province. This cost is assumed by employers, the workers and the society in general.

Noise-induced hearing loss is a sneaky disease, a workers’ hearing acuity deteriorates slowly and it can take years before the worker becomes aware of the state of his hearing. Hard of hearing individuals tend to isolate themselves from their entourage. At work, they hardly identify instructions, alerts or signals which is in itself a risk of injury.


As per the INSPQ, noise-induced hearing loss is the most costly occupational disease in the province of Quebec.



ODYO’s hearing conservation program is comprehensive and entirely offered by certified audiologists. Our services are offered on-site in your workplace and can be adapted to your needs to complement the current noise reduction measures in your environment.


Mobile hearing testing

Occupational noise evaluation

Using sound level meters and noise dosimeters, our audiologists will help you determine the current noise situation in your workplace environment. This is generally a good way to start a hearing conservation program. Occupational noise evaluations can be implemented to:

  1. Elaborate a noise map for your workplace environment.
  2. Evaluate or estimate workers noise exposure at different workstations.
  3. Identify the adequate noise reduction measures to implement.
  4. Estimate the effectiveness of future noise reduction measures.

Elimination of noise at the source

Based on your current noise map situation, constraints and objectives, our team will recommend noise elimination measures that will tackle noise before it reaches the workers ears. There are three types of noise reduction measures.

  1. Noise elimination at the source which implicates the choice of machinery and its components.
  2. Reducing the spreading of noise by limiting its transmission through walls, ceilings and flooring.
  3. Acting upon workers ears by offering adequate hearing protection solutions.

Hearing protection and custom ear plugs

Although this is often the easiest noise reduction measure, it should not be considered as the first option as it does not eliminate the noise problem at the source. However, if eliminating noise at the source is impossible or the noise levels are still too high, hearing protection becomes the best available choice. There are three types of hearing protection:

  1. Foam earplugs are the most common solution, but are they adequate for your business’ needs?
  2. Noise reducing earmuffs that are easy to maintain.
  3. Custom earplugs which offer the most durable, personalized and cost-effective solution.

Training and awareness activities

Training and awareness activities go a long way in reducing work-related noise induced hearing loss. In order to implement an effective hearing conservation program, workers must understand their responsibilities towards reducing the risk of hearing loss. Our training activities are offered by a certified instructor who is recognized by Emploi Québec. Topics covered during ODYO’s training sessions:

  1. Ear and sound
  2. Noise propagation and elimination
  3. Noise induced hearing loss
  4. Hearing protection
  5. Laws and regulations on the matter

Mobile hearing test

Mobile hearing test services are offered on-site at your location. We move sound proof booths inside your work environment to complete these tests. Mobile hearing test is an integral part of any hearing conservation program as it allows employers and workers to track the effects of exposure to noise on their hearing acuity. Here are some advantages of utilizing our mobile hearing testing services.

  1. Reduce workers lost time of production as the services are offered on-site.
  2. Personalized scheduling to reduce the impact on production lines.
  3. Control noise-induced hearing loss claims.

Adaptation of the workplace environment

To better integrate hard of hearing workers in a work environment, certain adaptation measures and technology must be implemented. At ODYO we offer assistive listening devices that amplify sound or transform them into tactile or visual cues. Therefore, a hearing impaired worker can perform his or her daily tasks in all safety and comfort.
