                                                  Principal Investigator     :   Dr. Krishnamurthy



I) Socio Economic Impact and Additional Cost Incurred in the upbringing of Persons

   with  Hearing Impairment in India

             Principal Investigator              :Mr.N.Karthikeyan

             Co-Investigators                    :Mr. Rajeev Jalvi

                                                         Mr. N. Ganesh

                                                         Mr. P.J. Mathew Martin                                              

             This research project aimed at conducting comparative study of the cost involved in the upbringing of persons with hearing impairment in India as against people without hearing impairment.  Loss of hearing leads to a devastating effect, no matter when it affects a person. The impact is pronounced when a person is unable to hear from birth or early childhood.                                                                                                                                                                                                                                                                                                                                                                            

             It is known that the type, degree, and age of onset of hearing loss are primary factors that determine the extent of its impact on the person affected.  However, where equitable services are not accessible, secondary factors such as gender, rural-urban divide, cost of quality of services, use of suitable technology, cost of transport, knowledge of service facilities and their outcomes tend to alter the life of person with hearing impairment.                                                                                                                                                                                                                                                                                                                                                                                                                       

             Therefore, cost of bringing up a person with hearing disability is much higher and strategies for inclusion should address both primary as well as secondary factors that contribute to the actual impact of hearing impairment in one’s life.                                                                                                                                                                                                                                                                                                

             The sample for the study includes persons with hearing impairment having identification age below 15 years and   below 30 years of age during data collection. They belong to all 4 regions of India.  Interview method was used to collect the samples by each research assistants. The time duration for interview varied from 20 to 30 minutes for each sample. The samples selected belonged to families belonging to three basic income categories, based on the color of the ration card, issued by respective State Govts.                                                                                                                                                                                                                                                                                                                    

             Samples were taken from the type of families from regions in north, west, east and southern parts of India.  The total sample consists of 1080 persons. The data analysis work has been completed and the report is being finalized for publication. The report with remarkable in-depth insight into the additional costs involved in bringing up of a person with hearing disability will be published soon.




            Following are some of the findings of the project -


             1.  The additional cost involved in bringing up of a hearing impaired child in terms of ‘Physical rehabilitation’ is Rs.9669/-.


             2.  The additional cost involved in ‘physical and educational rehabilitation’ is Rs.6129/- per year by a family in bringing up of a hearing impaired child as compared to a child without hearing impairment.  This is 2.5 times more than that required to bring up a child without hearing impairment.


             3.  Expenditure on education of children with hearing impairment in India is lower than those of ‘normal hearing children’ in all the age ranges.  There are some reasons for this. The disabled children go to special schools run by NGOs and Government where the fees are low, whereas the ‘normal hearing children go to private schools where fees are high. ‘Normal hearing schools’ avoid admitting hearing impaired children. Hearing impaired children get concessions in fees.  For ‘Normal hearing children’ parents engage private tutors, but for hearing impaired children there are no private tutors available.  ‘Normal hearing children’ attend coaching classes but hearing impaired children are not admitted to such classes.                                                             



   II)      Hindi Learning Package. The project is funded by Science & Technology Mission Mode, Ministry of Social Justice & Empowerment, Govt. of India


                                                  Principal Investigator    :     Mrs. Usha Dalvi

                                                  Co-Investigator           :     Mrs. Sadhana Relekar

             The aim of the project was to develop booklets in Hindi language in three sets viz., Varnasansar (3 booklets), Shabda Sansar (15 booklets) and Vakya Sansar (5 booklets) to facilitate the learning of the various aspects of phonological, syntactic and semantic rules of the Hindi language in children with hearing impairment and other language disordered children. Under this project 23 booklets and five CDs are developed.                                                     


  III)      Creation of Database of Organisations Working for the Persons with Disabilities in India            


                                                  Principal Investigator    :     Mr. N. Karthikeyan

                                                  Co-Investigator           :     Mr. Arun Kalbage


People and persons with disabilities need to know where they can get education, vocational

training and assistance for employment, etc. The database will be useful for general public,

persons with disabilities, parents, rehabilitation professionals, policy makers, planners and

implementers of welfare and development programmes.  Information was collected by writing

to organisations, schools, social welfare departments of states, State Disability Commissioners,

etc.  387 organisations have furnished the information and the same is compiled.


   IV)      A Survey of Role and Services Rendered by the Social Worker in Schools of Children with Hearing Impairment as Perceived by Parents and Other Professionals


                    Principal Investigator :Ms. Rekha More        


             The objectives of the Project are -  to study (i) the role of the social worker in special schools; (ii) various services rendered by social workers in special schools in Maharashtra; (iii) the views of the school principals about the nature of the work of the social worker employed and  (iv)  how these social workers communicate with children with hearing impairment. Some of the findings of the project are given below -                                                                                                                                                                     

             1) Among social workers, 90% had Master of Social Worker degree and 93% had more than 8 years experience.                                                                                                                                                                      

             2) They help to create awareness among society, raise funds and in integration of children with hearing impairment in regular schools.                                                                                                                                         

             3) In the role of counselor, the social worker counsels children with hearing impairment as well as teachers and parents.  He/she informs students, teachers and parents about different schemes of government.                                                                                                                                                                            

             4) The roles of social workers as self-learners also emerged during the study.  This initiative has helped them to work as an educational assistant in the special schools.                                                                                                                                                                         

             5) Social workers from special schools network  with other institutes and other professionals.                                                                                                                                                                                            6) The study recommends that there should be an evaluation of the work,  on the job training for upgradation of skills,  and suitable encouragement from authorities.           







      I)      Deafness in India : A Network Mission Towards Understanding the Genes & Mutations and their Clinical Outcomes. The Project is funded by  Dept. of Bio-Technology, Govt. of India (Multicentric study being  done in collaboration with JNCASR, Bangalore, MAMC, New Delhi and PGIBMS, Chennai)

                                                         Investigators                 :                                                  Mr.R.Rangasayee

                                                                                                            :                                                  Dr.Anuranjan Anand

                                                                 Co-Investigator             :     Dr. Kamal Parasram

               It is a service based project to initiate genetic screening programme  in the country to bridge the gap between deafness gene discoveries  and application of genetic information to improve diagnosis, rehabilitation, management and prevention  of hearing impairment. This project is taken up with the following objectives -

          To create detailed data base of the deafness gene mutations by using modern technology;

          To develop cost-effective,sensitive and non invasive technologies for such diagnosis;

          To study the nature of Cx 26 & TMC1 mutations in India including their prevalence, audiological consequences & differential clinical correlates;

          To build up an easily accessible data base that will be useful for the purpose of accurate and high quality genetic counselling services and training of professionals in this area.

             Progress made during the reporting year is given below -

               Four new mutations of known genes have been identified.  The study has given lead to prevention of Non syndromic Deafness in India.                                                                                                                                                                                                                      


  II) Screening of Hearing in Infants - A Pilot Project (SHIP)

                                                          Investigator               :      Dr. Vijayalakshmi Basavaraj                                    Co-Investigators                  :     Ms. Aparna Nandurkar                                                                                                 Dr. Ruchi Nanavati                                                                                                                                           

                     The project was conducted from 2005 to 2007 and subsequently extended to 2008 to suggest a cost effective newborn screening module for identifying children with severe to profound hearing loss in the country.  A total of 1238 infants were enrolled in screening at KEM hospital, Mumbai with an age range of 0 – 6.5 months among which 1020 were identified as high risk infants whereas the rest 218 were identified as no-risk infants according to the Joint Committee on Infant Hearing (2000) criteria. Screening was carried out by three different techniques (Behavioral, TEOAE, ABR) and three different personnel.

For the high-risk group, sensitivity and specificity of behavioral screening technique for

identifying severe to profound hearing loss in infants has been found to be 100 % for all the

screening personnel: mother, nurse and audiologist.  It was found that a prevalence rate of

1.61 is seen for profound hearing loss in a population of 1000 high-risk infants in India.  For a

country like India, where facilities for using sophisticated instrumentation are not available at

many places and trained personnel are not placed at smaller clinics and centers in small towns,

a feasible option would be to implement a three-tier screening module for identifying infants

with severe to profound hearing impairment, such as the one outlined below.


Initial behavioral screening by the mother/caregiver, which may be extended to an anganwadi

worker, a dai or a community worker


TEOAE screening by nurse at local PHC or hospital using automated equipment Refer to

audiologist for further assessment                                  


III)  Development of Study Materials for B.Ed.(H.I.) Trainee Teachers

                                                          Investigator               :                                           Dr.Arun Banik

                                                          Co-Investigator         :                                           Mrs.Balaka Mitra      


             Considering the needs of the teachers of children with  hearing impairment, a project on ‘Development of study material for B.Ed(H.I) trainees’,  has been under taken.


             The study materials focus on giving relevant, recent information facilitating self-study and management  skills in student trainees. Under this project,  five text book materials have been compiled for B.Ed. (HI) teacher trainees in English as an outcome of the project.  All the material is now ready for printing with minor modification and editing as well.  Further, the material is also available in CD form.      






I)  Conduct Problems among Children with Hearing Impairment in Specia Schools


                     Investigator                         -  Mrs. Alka Sapru-Joshi

                     Co-Investigator                               -  Dr. Geeta Rao


              The project was undertaken in order to establish the ‘risk rate’ of Conduct Disorder, the frequency of occurrence of particular conduct problems and to shed light on the socio-demographic and audiological correlates of those conduct problems among 5 to 18 year old children and adolescents with hearing impairment. 


             A sample of students (male - 316; female - 202) were rated by 113 teachers (male - 12; female - 101) with an average of 17.5 years of teaching experience on the Conduct Disorder Scale (Gilliam, 2002).  The number of children / adolescents identified as being at risk of Conduct Disorder was established at 27 i.e. 5.21% of the sample with a female to male ratio of 1:5.75.  The majority i.e. 12 (44.44%) fell in the age range by 13.1 years to 17.9 years.  It was observed that 22.73% were only children and 59.09% were found to be first born.  Congenital loss was reported in 75% as against acquired loss in 25%.  Sensori-neural hearing loss was seen in 60% while 40% reportedly have mixed hearing loss.   


             Since many variables could not be analyzed statistically due to  very small sub sample of students identified as ‘at-risk’, a frequency tabulation was done to establish the most commonly encountered conduct problems.  The five problems most frequently cited by teachers were established as:


                     ·         Argues with adults

                     ·         Starts fights

                     ·         Blames others for his or her mistakes or misbehaviours

                     ·         Creates disturbances

                     ·         Deliberately annoys people


             Given the fact that patterns of behaviours acquired early in life tend to persist or exacerbate, mental health workers, and educators of youngsters with hearing impairment need to work on evolving intervention approaches and strategies to minimize the occurrence and sequel of conduct disorders.



   II)    Profile of Post Training Activities of Rehabilitation Professional with Reference to Persons with Hearing Impairment in India in the last Five Years


                     Investigator                         -   Mr. R. Rangasayee


            The aim of the study was to collect information on the current occupation, current salary, job security, use of technology, social status associated with profession, level of burnout in professionals who deal with hearing impairment and communication disorder.


             A Research tool was constructed for collecting details of demographic data in terms of age, sex, contact no., email, gender, current working state. 380 professionals were interviewed for the purposes of the study.  The following are the results:


             Current occupation -

             55% of the professionals are employed in NGOs, 20% in Govt.,   5% in academic institutions & remaining 20% in other activities.  While 40% are salaried, 8% are self employed, 20% are freelancing, 4% in research oriented work, and 28% engaged in other activities.

             50% hold contract positions, 30% are permanent employees, 16% work part time, 4% serve as visiting faculty.


             Monthly income -

             Most of the professionals (57%) earn Rs.3000-10000/-,  while 11% are in the lower income group with less than Rs.3000 as their monthly income.  11% earn 10000-20000, 20% earn between Rs.20000-40000/-, 1% earn above 40000/-.


             Computer facility -

             These are available to about 76% for their professional activities.


             Savings -

             A sizable number of professionals (76%) think that their salary is not commensurate with their training as compared with those of other professions who undergo the same years of training.  35% of them save less than 6% of their salary on a monthly basis.  While savings of 6-10% are made by 7% of professionals, 11% - 30% savings are made by 47% of professionals.  The remaining save above 30%.


             Job satisfaction  -

             Only 27% of these persons are satisfied professionally.  Remaining 73% are not fully satisfied.  Of this, 18% feel stressed due to the nature of their jobs.  Further, merely 43% feel that their job enhanced their status and 42% recommend the profession to others.


             It is inferred that there is need to improve the satisfaction of professionals in terms of salary and other facilities.


 III.    Development of Low Cost Noise Level Indicator with Audio Visual Alarms


                     Investigator                         -  Dr. S.G.R. Prakash

                     Co-Investigator                    -  Mr. P. Jeethendra  



Children in an Inclusive education setup find the noise as a big barrier in the learning process, and acquisition of the literacy skills. Noise affects the real time learning environment during the teaching by the teacher in the classroom. This noise is created in the classroom by the students and other sources in the school. Noise also increases the stress on the teacher to teach efficiently in the noisy environment.

To find out how much of the noise is there in the surrounding environment and maintain the noise levels to a desired level, the noise can be measured using  Sound Level Meters but these would work out costly if equipped in  every classroom. Hence the objective of this project was :

•    To develop a simple, low cost,  low maintenance, high visibility, scientific device for monitoring the noise in the inclusive classroom which will help in creating an enhanced learning environment for the students with normal hearing and students with hearing impairment and reduce the stress levels of the teacher.


The researchers at AYJNIHH – SRC have designed and developed a Low Cost Noise Level Indicator. This Noise level Indicator has been developed by using  locally available electronic  components with in-house design of the circuitry at SRC – Secunderabad.


The Noise level indicator has three stages -  a. Noise Acquisition,     b. Filtering and Amplification and

c. Triggering and visual representation.


Features and description of NLI -                                                                                                                      

•    Power requirements   - 230 V , 50 Hz ac supply

•    Power consumption    - Less than 10 W monthly

•    Weight of the kit        -  About  one KG, wall hanging type with three bulbs preferably 10W each

•    This is a 230 V, 50 Hz, AC operated device and care should be taken while opening the kit, as it may give electric shock.

•    NLI is intended to measure the noise levels from 50dBSPL – 100dBSPL.

•    The unit can also be set for pre determined level depending on the purpose, e.g. in the classroom, the levels can be varied at different level in the range of 50 to 100 dB level.

•    This can be used at three different predetermined intensity levels

•    Indicates the visual  alarm using  three indicator bulbs


Costing of the NLI


•    The cost of production of each unit  would be approx. Rs.1300 in single piece manufacturing

•    If orders are taken in bulk (around 100) the cost can be brought down to 15% less.


Other applications - This can be used as :

•    Noise measurement tool at various traffic junctions

•    In libraries for maintaining the noise levels

•    To remotely observe the noise levels by placing the microphone in the area where noise is to be measured and connecting it to the device where it has to be monitored

•    Voice therapy cases in loudness enhancing techniques

•    In work places -  shows employees when it is time to wear hearing protection. The use of the warning sign helps to attract attention

•    In Hospitals, Offices and Call centres to give staff an unbiased view of the noise levels they are creating, using strategically placed devices

•    Warning signs gives a direct unavoidable message - reduce your noise

      •   In pubs and clubs can be used as warning device.
