- severity & type of hearing loss
- The subject is asked to remove anything which might upset the test results, e.g. spectacles, earrings, hearing aids.
- Instructions are given about the test procedure and the subject is required to indicate whether he/she can just hear or cannot hear a certain sound (the sound level may be increased from a very low level or reduced from a high level).
- Headphones are fitted carefully over the ears and the test is then carried out on each ear.
