A person with hearing loss which cannot be surgically or medically corrected is rehabilitated with amplification devices. Hearing aids are amplification devices which serve to amplify the acoustic signal to a level which is audible to the hearing-impaired listener. Hearing aids do not restore hearing ability but they boost up the signal so that the hearing impaired listener is able to use up his/ her residual hearing to hear the amplified signal. Though initially hearing aid technology was analogue based, with the advent of technology, digital technology is implemented in today’s hearing aids.
At NISH, once the patient is identified with hearing loss which is medically or surgically incurable, the patient is referred for hearing aid trial and fitting. Hearing aids are available in different styles including Behind the Ear hearing aids (standard BTE, mini BTE, open fit type BTE), Receiver In the Ear, In the Canal, In The Ear, Completely in the Canal, Pocket level hearing aids etc. Digital hearing aids from world-class hearing aid manufacturers are available at NISH at concessional rates.
Hearing aid selection and fitting is based on objective and subjective measures. Free field Aided thresholds, speech measures are utilized for assessing functional benefit with hearing aid. In addition, NISH is equipped with Hearing aid analyzer and Real Ear measurement systems for objective evaluation of the hearing aid performance.
After the purchase of hearing aids, the hearing aid user is oriented and counselled regarding the care and maintenance of hearing aids. Availability of facilities for reprogramming in cases of programmable hearing aids and servicing of hearing aid provides the hearing aid users with good after sale services.
