2. A hearing test consists of two methods- the first one to know howyou respond to tones of varying volume and pitch and the second,to test your understanding speech by the use of different words.Another test known as Immitence test automatically determines themobility of your ear drum and the related functioning of the spacesurrounding the middle ear. In addition to these tests, you may berequired to undergo other specialized tests depending upon thefindings of the earlier findings and your age. 3. Your ear is constituted of three layers namely the outer ear, themiddle ear and the inner ear. The outer ear or pinna includes the earcanal and is located to the side of your head. It receives the soundwaves and feeds into the ear canal. Ear drum is a tympanicmembrane and is attached to the end of ear canal. The soundwaves vibrate the eardrum, beyond which exist three tiny bonescalled ossicles that transmit the sound to the inner ear. Themovement of ossicles make the fluid within the inner ear or cochleato move thus stimulating tiny nerves called hair cells to sendelectrical impulses to your brain. This creates the sense of yourhearing. 4. Hearing loss is of different types. Sensor neural hearing loss ariseswhen the tiny hair cells in the cochlea or hearing nerve to your brainare damaged. This may be caused due to age, consistent exposureto noise or genetic effects. It can be treated by amplification ofhearing. When the outer or middle ear is not functioning properly,you are subjected to conductive hearing loss. It is caused due toinfection, holes in the ear drum or impacted wax and can be treatedby medication or surgery. Mixed hearing loss is a combination ofboth of the types and can be corrected by either amplification or bymedication/surgery 5. There are audiologists who can undertake up hearing tests ofinfants and children of varying ages through a number of testssuch as Otoacoustic Emissions (OAE), Visual ResponseAudiometer (VRA), Conditioned Play Audiometer CPA),Conditional Audiometric (CA),Auditory Processing Disorders (APD)or Tympanometry. Adult hearing can be evaluated by tests such asDiagnostic Hearing Evaluation (DHE), Balance Function Testing(VNG), Tinnitus Assessment and Retraining Therapy (TART) andPersonal Amplification Devices and Accessories (PADA). 6.
