The Process of Hearing and the evaluation of hearing loss

1. The Process of Hearing and the evaluation of hearing loss

2. A child learns by hearing. Like the other four senses, hearing is essential for an everyone. The process of hearing starts with the sound waves entering the external portion of the ear & then channeling through the auditory canal which is structured like a tube. It has tiny hairs and tiny glands which make wax inside the ear. Middle ear starts where the auditory canal ends. Here lies the eardrum & three tiny bones known as hammer, anvil and stirrup. Sound waves vibrate and move the hammer, which in turn moves the anvil. The vibration is then transmitted to the inner ear through the movement of the stirrup.

3. The middle ear amplifies the sound and any disorder here may lead to hearing loss. The inner ear is constituted of cochlea and the nerve of hearing. Sound waves are converted to nerve impulses here, and sent to the brain by the movement of miniature cells of hair. Brain interprets the impulses and makes you to hear and understand the message sent to you by the speaker. In case of any kind of distortion, disruption or disturbance in the whole process of hearing, ‘hearing loss’ will be causes.

4. Triangle Hearing services include evaluation of diagnostic hearing for different ages, emission of otoacoustic, supply, consultation, repair and fitting of hearing aids, immittance testing for mobility of eardrum, assertive devices for listening, frequency modulated system, diagnosis and treatment of tinnitus, evaluation of CAPD, swim plugs devices for protection of earmold hearing and earbuds for iPods and MP3 players. You can get any kind of services or accessories related to hearing aids NC.Proper hearing needs to be ensured from a very early stage. In case you observe any kind of deviation in hearing with your children, you can opt for triangle hearing services for evaluation of pediatric hearing.

5. Otoacoustic Emissions evaluates the functioning of the outer hair cells Visual Response Audiometry(VRA) is applied for determining the hearing propensity of the child Conditional Play Audiometry(CPA) evaluates response of the child to different frequencies and intensity of sound Conventional Audiometry(CA) determines child’s hearing levels Basic Immitance Test Battery evaluates the response of eardrum to sounds Auditory Processing Disorder or APD is best applicable to school-going children who exhibit problem in hearing and learning. Techniques through which the hearing loss could be evaluated for proper remedial measures

6. Evaluation of hearing loss with adults could be conducted by a number of testing procedures such as; Pure Tone Audiometry measures ability to hear at various pitches and volumes, Word Recognition Testing evaluates the ability of understanding and responding to speech, Basic Immitance Test Battery evaluates the response of ear drum to sound and detection of fluid in the middle ear.Tinnitus is a kind of ringing or roaring sound, generated internally. This may annoy or even incapacitate you. It is caused due to neurological changes in the auditory system. For more Information:- audiologist cary
