Hearing Impairment is a silent, invisible handicap.  It can develop due to various pathological conditions.

It can be of various types, e.g.

  • Conductive  Hearing Loss
  • Sensorineural Hearing Loss
  • Mixed Hearing Loss

Conductive LossSensorineural loss

Similarly the degree of hearing loss may vary in individuals from

  • Mild
  • Moderate                | This is determined by audiogram tests
  • Severe
  • Profound

Degree of hearing loss refers to the severity of the loss. The table below shows one of the more commonly used classification systems. The numbers are representative of the patient’s hearing loss range in decibels (dB HL).

 

 

 

Although the hearing loss is labeled as ‘profound’, it may well vary from person to person in its effect.

Some children may show poor academic progress and be labeled ‘lazy’ or ‘inattentive’ – although they may have average or above average I.Q.

This often leads to poor self concept and the child, may lack self confidence and be labeled deaf and ‘dumb’ (with all its conotations), even by those in authority.

Hence to reduce the impact of hearing impairment, early diagnosis and appropriate intervention is essential (see ‘Early Intervention’)

Once the degree of hearing loss is established, if cochlear implant is not possible or suitable for the child, a purpose designed and appropriate hearing aid must be fitted and reviewed regularly.

The majority of children studying at RMSD come from poor socio-economic backgrounds (see ‘Pupil Profile’) and the condition has not been recognized and managed in infancy.

On entering the school, the full extent of the loss is assessed and the child is fitted with a custom built hearing aid appropriate to the degree of loss.  Auditory training and speech therapy is started in addition to the academic syllabus which the children are taught.  Language and communication skills are developed along with English language .

In order to do this, we

  1. Provide digital and quality individually designed hearing aids to all children based on their degree of hearing loss .

  2. B.T.E. hearing aids are provided to all students with individually designed ear moulds which are carefully fitted and changed as the child grows

  3. Speech therapy is given regularly by trained teachersIndvidual-speech

We aim to develop intelligible speech in the child so he/she can take his rightful place in the hearing world.
