In most cases hearing loss occurs gradually, which is why it’s a good idea to test your hearing regularly in order to track changes over time. People over 55 years of age or those who work in environments with noise exposure above 110dBA should get their hearing tested every 12 months. We ensure our Hearing Instrument Specialists are not only certified but also receive training regularly as to maintain the standard that customers like you, have come to expect from KG Safety Services.
There are two types of audiometric testing, baseline testing and periodic testing. A baseline test is the first audiometric test that is done when the employee starts with the company.
The first periodic test is done 12 months after the baseline test was conducted. Subsequent periodic tests are conducted every 24 months thereafter. There are a few exceptions to these rules:
- Annual testing must be conducted if the results of past tests are abnormal for that employee
- If the noise exposure level exceeds 110 dB, testing must be completed twice per year
Components of the KG Safety Services program:
- Completion of noise exposure history
- Examination of ear with Otoscope
- Complete health teaching and current hearing protection assessment and recommendations
- CSA approved equipment and technology
- Audiometric testing services that meet the highest level of legislative compliance in North America.
Our Audiometric Testing Program includes assessment, worker education and orientation to noise levels, and the use of personal protective equipment.
It is important that employees be aware of when, why and how to use their hearing protection. This encourages compliance and a healthy work environment. The Occupational Health and Safety Code provides tables to help employers determine when and what kind of hearing protection is required. According to these tables, exposure to noise at 85 decibels for 8 hours is permissible without the use of hearing protection. As noise level increases by 3 decibels, however, the amount of time permissible to be exposed is reduced.
A heavy duty vehicle at 90 decibels is permissible for 2 hours, otherwise the risk of permanent hearing loss is present with repeated exposure. Some other good examples of noise levels are: a vacuum is 80 decibels, an ambulance siren is 120 decibels, and normal conversation is 60 decibels.
KG Safety Services uses a secure software program to electronically track each employee’s audiometric history with the company. This data can be used to help determine if the policies and procedures for hearing conservation in place are working, as well as if the right type of hearing protection is being used effectively.
Audio tests are reviewed by an associated MRO (Medical Review Officer)/physician.
