Audiograms

Audiogram testing is a screening method that tests pure sounds with an arbitrary zero reference level. If you can hear these tones up to 25 dB, your hearing is considered to be normal. This testing does not discriminate between causes of loss, and if your levels are significantly above 25 dB, or one ear is significantly worse than the other, you may be referred to a specialist to determine other causes of hearing loss or ear disease. Healthy Trust Occupational Health does hearing testing using a standard technique to help to get the best test available and allows comparison of your tests year to year to eliminate errors. Our technicians are certified by the Council For Accreditation In Occupational Hearing Conservation (CAOHC), our equipment is approved by the National Institute for Occupational Safety and Health (NIOSH), and our booth is OSHA certified.
