How We Find Out About Your Hearing
Manually recorded pure tone audiometry is available from Hearbase. We carry this out in accordance with the British Society of Audiology procedures.
For a hearing test you will sit in a soundproof booth with a set of headphones over your ears. These are connected to an audiometer.
This produces tones at specific frequencies and levels to each ear independently. Our audiologist will plot the loudness on an audiogram and you will press a button each time you hear the tone.
The audiologist will test and plot each frequency of normal hearing ability and then join these points by a line. This is so our audiologist can see at a glance the frequencies you can’t hear normally and the degree of hearing loss.
Tympanometry is an examination to test the mobility of the eardrum and the condition of the bones within the middle ear. This is done by creating variations of air pressure in the ear canal.
This is an objective test of middle ear function. It is not a hearing test, but rather a measure of energy transmission through the middle ear.
The test should not be used to assess the sensitivity of hearing. We always view the results of this test in conjunction with pure tone audiometry. This is a very quick procedure and has minimal discomfort.
We carry out this test using the British Society of Audiology’s procedure for best practice, as published in the British Journal of Audiology.
This is an objective measure of cochlear function and a reliable indicator of inner ear function.
Oto-acoustic emissions are clinically important because they are the basis of a simple, non-invasive, test for hearing defects in newborn babies and in children who are too young for conventional hearing tests.
