Audiometry test is conducted to test the ability to hear different sounds and pitches. It is non invasive and painless procedure and includes tests of mechanical sound transmission (middle ear function),
neural sound transmission (cochlear function), and speech discrimination ability (central integration). It is also used to determine or monitor the hearing loss after or before the surgery when a patient has tumor in or around the ear.
Hearing loss comes with the age but other factors contribute too. Therefore, it is better to have this test since you feel something wrong as it will reduce the severe problems in future. At Concept Diagnostics, we have trained audiologists who will perform the whole test with care and safety and get you the best.
The unit of measure for sound intensity is the decibel (dB). Human can hear the soft whispering sound
which is about 20 dB, loud music is around 80-120 dB and a jet engine is about 140-180 dB
Common way to classify Hearing Loss.
|Degree of hearing loss||Hearing loss range (dB HL)|
|Normal||10 – 15|
|Slight hearing loss||16 – 25|
|Mild hearing loss||26 – 40|
|Moderate hearing loss||41 – 55|
|Moderately severe hearing loss||56 – 70|
|Severe hearing loss||71 – 90|
|Profound hearing loss||Above 91|
How is Audiometry Test Performed?
The audiometry test is performed by a trained audiologist. This test is conducted in a quiet soundproof room. Standard headphones or inserted earphones are placed properly. You need to sit still and quiet while testing. The earphones will be connected to a machine that will transmit different sounds to your ears. Sample sound will be played for you and you will be asked to raise the hand to confirm whether the sound is audible or not. A turning fork may be used to determine how well you hear vibrations through your ears. The tuning fork is tapped and held in the air on each side of the head to test the ability to hear by air conduction. It is tapped and placed against the bone behind each ear (mastoid bone) to test bone conduction. After the test, our audiologist will review your results and will guide you correct for further measures to be taken.
