If you\’re worried about your hearing or your loved ones hearing it’s easy to get it checked in Trivandrum, Kerala South India.
First the ENT surgeon see and examine the ears and will be send to an audiologist for hearing evaluation.
An audiometry evaluation is a painless, noninvasive hearing test that measures a person\’s ability to hear different sounds, pitches, or frequencies.
Simple hearing screening tests are done by a whisper test and tuning Fork tests before proceeding to full Audiometry by an audiologist.
Whisper Test is done by blocking one ear at a time and checking ones ability to hear whispers, spoken words, or the sound of a ticking watch.
Tuning fork tests is also done. 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 mastoid bone behind each ear to test bone conduction.
A full hearing test will confirm that you have a hearing problem and establish the type of hearing problem that you have.
During the hearing test, the patient will sit in a soundproof booth or room with headphones on while the audiologist presents a series of sounds. When the patient hear a sound, he or she will signal to the audiologist, normally by pressing a button or raising your hand.
What does a hearing test show?
Pure tone audiometry chart called the audiogram shows the hearing level of different tone frequencies in both ears. On an audiogram chart, red O’s indicate the right ear’s results and blue X’s the left ear’s results.
To assess speech discrimination, you will be instructed to repeat words you hear. You will hear a series of two-syllable words at a volume that gradually decreases as the test progresses. In the second stage of the test, you will hear and repeat a series of one-syllable words at a volume that does not change.
During a tympanometry and acoustic reflex test, a soft plug is placed in your ear. The plug will change pressure, make a loud noise, and track your responses to the sound and various pressures. Movement of the eardrum is measured as well as the reflexes of the tiny muscles attached to the ossicles.

and Normal = less than 25 db HL
and Mild = 25-40 db HL
and Moderate = 41-65 dB HL
and Severe = 66-90 db HL
and Profound = more than 90 db HL
