Audiometry hearing test is used to assess conditions of tinnitus, hearing loss, deafness & presbycusis. Hearing loss comes with age but can affect anyone. Studies showed at least 25 percent of people over 50 experience hearing loss, and 50 percent of people over 80 experience it. One way to test for hearing loss is to use audiometry.
Noise-induced deafness NID
NID is a condition where there is permanent loss in hearing sensitivity. This can cause communication difficulties, social isolation and adversely affect quality of life. In the workplace, NID can be caused by prolonged exposure to excessive noise generated by industrial processes and work activities, and is compensable under the Work Injury Compensation Act.
A hearing test or pure tone audiometry is to find out the softest levels of sound a person can hear at individual pitches of sounds (hearing thresholds). At Bethesda our hearing test is done in sound-proof booth and conducted by technicians trained and qualified in industrial audiometry.
- Pure Tone Air Conduction Audiometry
- Our pure tone audiometric testing assess hearing across the speech spectrum. You need to listen out for various beeps and sound, and press a button as you hear them. The softest sounds that you are able to hear will be marked on a graph called an audiogram.
- Pure Tone Bone Conduction Audiometry
- This test determines the area in the ear where the hearing problem lies. Hearing loss originating from the middle ear can often be medically treated. However, if the hearing loss is in the inner ear then there is greater likelihood that it is permanent hearing problem that may need hearing aids.
