HEARING IMPAIRMENT (DEAF AND HARD OF HEARING)
20.1. Definition:
(a) “Deaf” means persons having 70 DB hearing loss in speech frequencies in both ears;
(b) “Hard of hearing” means person having 60 DB to 70 DB hearing loss in speech frequencies in both ears;
20.2. Guidelines for Assessment:
20.2.1. Measurement Air Conduction Thresholds (ACT):
(a) ACT is to be measured using standard Pure Tone Audiometry by an Audiologist for Right Ear and Left
Ear separately.
(b) In case of non-reliable ACT, additional tests are recommended such as Immittance, and Speech
audiometry or Auditory Brainstem Response (ABR) Testing.
(c) Measuring ACT may be difficult in children aged 3-5 years. In such cases, Conditioned Pure Tone
audiometry/Visual Reinforcement Audiometry (VRA) shall be conducted. ABR or Auditory Steady
State Response (ASSR) testing can be advised for the estimation of ACT in infant and young children.
20.2.2 . Computation of Percentage of Hearing Disability:
(a) Monaural Percentage of Hearing Disability
(i) Calculate Pure tone average of ACT for 500 Hz, 1000 Hz, 2000 Hz, 4000 Hz for Right Ear and Left ear
separately (whenever there is no response at any frequency ACT is to be considered as 95dB).
(ii) Monaural percentage of hearing disability is to be calculated as per the ready reckoner given below
separately for Right Ear and Left Ear.
