What is a hearing test?
A hearing test, also known as an audiometric assessment, is a specialised evaluation conducted by a qualified audiologist to measure an individual’s hearing sensitivity and identify any hearing impairments. This non-invasive procedure helps determine the extent and nature of hearing loss, aiding in the development of appropriate management strategies.
Why is a hearing test conducted?
Hearing tests are performed for several reasons:
- Diagnosis: To diagnose hearing loss or related conditions and determine their severity.
- Baseline evaluation: Establishing a baseline of an individual’s hearing abilities for future comparisons.
- Treatment planning: Guiding the selection of appropriate hearing aids or other interventions.
- Occupational health: Assessing hearing capabilities of individuals in noisy workplaces.
- Preventive care: Detecting early signs of hearing loss and taking proactive measures.
What does a hearing test involve?
A hearing test typically comprises the following components:
- Pure tone audiometry: Using headphones, you listen to different tones at various volumes and indicate when you hear them.
- Bone conduction test: Similar to pure tone audiometry but conducted through a bone vibrator placed behind the ear to bypass the outer and middle ear.
- Speech audiometry: Assessing your ability to hear and repeat spoken words or sentences at different volumes.
- Tympanometry: A test that measures the movement of the eardrum in response to air pressure changes, evaluating middle ear function.
- Otoacoustic emissions (OAEs): A test that measures the sounds produced by the inner ear in response to sound stimuli.
