B. Clinical Services

The department offers a whole range of clinical services, to individuals starting from a few days old to elderly. The activities include prevention of hearing loss, assessment of hearing, selection and fitment of hearing devices, provision of custom ear molds and rehabilitation of the individuals with hearing impairment. These services may be broadly categorized as hearing evaluation and audiological management.

1. Hearing evaluation: 
  • Hearing evaluation involves a detailed assessment of hearing. The hearing evaluation is carried out using behavioural tests as well as objective tests. Differential diagnosis of the hearing problem is done based on the results of a battery of tests using state-of-the-art equipment. In addition, tests are available for evaluation of tinnitus, hyperacusis, cochlear dead regions, auditory dys-synchrony, and central auditory processing disorder (CAPD).
  • The major behavioral tests used at the department are Pure Tone Audiometry and Speech Audiometry. Facilities to carry out Behavioral Observation Audiometry (BOA) and Visual Reinforcement Audiometry (VRA) are also carried out. With VRA it is possible to obtain voluntary responses to sound stimuli from children as young as six months of age.
  • Using objective tests, responses to auditory stimuli can be obtained without voluntary response from the individual. The objective tests used at the department include, Immittance evaluation, measurement of Oto Acoustic Emissions (OAE), measurement of Auditory Evoked Potentials (AEP) and Auditory Steady State Responses (ASSR).
  • After the hearing assessment, appropriate referrals or rehabilitative procedures are recommended. The referral could be for a medical / surgical line of treatment. Audiological treatment when recommended will be carried out at the department.
2. Audiological Management:
  • Hearing devices fitment: A number of hearing devices including different types and models of hearing aids and Assistive listening Devices (ALD) are available for trial. Usually, hearing aids are prescribed to those who do not benefit from a medical line of treatment. The hearing aids prescribed include body level and ear level (Behind-the-ear, spectacle, in-the-ear, receiver-in-the-canal hearing aids, in-the-canal & completely-in-the-canal hearing aids) devices. Conventional and digital hearing aids are available for testing clients. Specific evaluations are carried out to assess the benefit from hearing devices in order to select the most appropriate device for the client. For eligible clients, body level hearing aids are provided at free of cost or at a subsidized rate under the scheme of Assistance to disabled persons for purchase / fitting of aids / appliances (ADIP scheme). ALDs help the persons with hearing impairment to obtain additional information in situations where a hearing aid alone may not be sufficient. These devices enhance perception of the signal, such as the sound of a doorbell, telephone ring, aid in telephone conversation and listening to television.

    Assessments are also carried out to determine candidacy for Cochlear Implant. Facilities are also available for programming the speech processors of the cochlear implant and evaluating the benefit from cochlear implants.
  • Hearing aid dispensing scheme: The department of Audiology has been successfully running a hearing aid dispensing scheme since 2006 - 07. Through this scheme, clients can procure the prescribed hearing aids at a discounted rate which are being dispensed to the clients. These hearing aids include devices other than those dispensed by the Government of India under the ADIP scheme.
  • Ear moulds: An ear mould is used to couple specific types of hearing aids to the ear of the user. Facilities are available at the department for providing custom hard moulds, soft moulds and custom in-the-ear and canal type of hearing aids. A Central Prosthetic Lab has also been established in the department as part of the 11th Five Year Plan. In this Lab, ear impressions (received from different centres where facilities for making moulds are not available) are processed and the custom earmolds are sent back to these centers. In order to promote the use of custom earmolds, different groups of individuals are trained so that they are able to make ear impressions and send them to the Lab for processing.
  • Counselling: Audiological management does not stop with the fitting of hearing devices. Clients are trained/counselled regarding their problem, need for hearing device, hearing device care and its use. Information on how to get the maximum benefit from a device, and adjust to hearing device is also imparted. They are also given guidelines on enhancing listening skills, speech reading and communication strategies. Pamphlets on these aspects are also given to clients.
  • Listening training: Clients who have difficulty in communication due to hearing imapirment are provided auditory learning/auditory training after fitted with appropriate hearing devices. In addition, some of the clients are provided speech reading training and taught to use communication strategies. Management of clients with special auditory needs such as auditory processing disorders, auditory dys-synchrony, tinnitus, and hyperacusis is also undertaken. The duration of therapy depends on the age of the individual and the amount of problem faced by the person. For outstation clients, demonstration therapy is given. Home training programs are given to all clients.
C.Extension services
Camps are conducted in rural and tribal areas where disability certificates and hearing aids are distributed to eligible clients.
D. Public Education
Public awareness is created regarding prevention, identification and rehabilitation of hearing impairment. Print and audiovisual material such as pamphlets, posters, slides, videos and models are prepared and also used for public education activities.
