Electrical response audiometry (ERA) in infants.
The electric response audiometry is a useful diagnostic technique for identifying hearing loss in infants. Among the various electrical responses, the BSER enables us to arrive at an accurate early clinical diagnosis of hearing loss in infants so that effective auditory input, which is the prime requisite for the conceptual foundation for the growth of communication, can be provided through appropriate intervention programmes. The electric response audiometry provides information regarding the physiologic state of the peripheral organs and auditory pathways but however, cannot ascertain whether the infant can hear, in terms of perceiving auditory information. Inspite of this major limitation, the growing acceptance of brainstem electrical potentials in clinics and laboratories throughout the world attests to their increasing importance especially in the assessment of hearing sensitivity of infants.
