The Occupational Health and safety code part 16(noise) requires employers to ensure noise exposed workers undergo audiometric testing. An audiometric technician must conduct the audiometric test.
The ear is a sensitive instrument and can be literally destroyed by disease,certain drugs,or noise.As audiometric technicians noise induced hearing loss is our primary concern. Noise is a leading health hazard in the workplace and a leading cause of all hearing loss.
A burst of high intensity noise, such as an explosion,can cause sudden,permanent deafness. The hearing loss from long term industrial noise exposure is more insidious.Much hearing damage occurs without the worker being aware until it is too late. The ears do not bleed, there is no pain and frequently the noise does not seem particularly loud. Hearing conservation is not always easy to promote. The biggest challenge in hearing conservation is getting the worker to wear adequate hearing protection on a consistent basis.
As a Technician will be responsible for :
Educating workers; counselling at time of test
Categorizing the test results and referrals to the physician and referrals to the physician and audiologist when indicated.
Record keeping-maintaining the audiometric test data, case history information is under the sole control of the physician, audiologist, or occupational health nurse designated by the employer.
Our Smart Tone Audiometer referred to, as microprocessors are prevalent in Alberta.They are pure tone audiometers in which signal presentation, frequency and hearing level selection are completed by the audiometer. When the worker hears a tone, they press the button and the response is recorded. Based on the worker’s response,thresholds are calculated and then presented on a read-out in numerical form at the end of each test. Most machines will indicate those thresholds that are questionable, and should be re-tested. A poor test environment leads to invalid results.
