We assess adults’ hearing using three different tests:
- Pure tone Audiometry
- This test involves tones presented at a range of frequencies to each ear individually under head phones.
- The client responds by pressing the button when they hear a sound, even if it is extremely soft.
- The Audiologist records the softest sound that is consistently responded to at each frequency ( the “hearing thresholds”).
- Hearing thresholds are measured at a range of frequencies that make up speech sounds.
- Normal pure tone thresholds are at 20dB HL of better.
- Speech Testing
- If you have hearing difficulties, speech testing is also performed.
- This may include listening to single words under headphones or listening to sentences while noise is playing simultaneously.
- Speech testing gives an idea how well you may respond to the use of a hearing aid.
- Middle ear and Eustachian tube function testing
- Tympanometry is a test that will indicate whether there is a problem with how the eardrum is functioning.
- The test is done simply by placing a small probe in the ear canal while the probe delivers a soft buzzing noise and a puff of air into the ear canal to test the response of the eardrum.
- An abnormal result is seen if there is a hole in the eardrum, or fluid in the middle ear
