Introduction


Behavioral hearing tests affect the child to show an overt repartee to an auditory stimulus. The response may be a head turn or a play such as a pinpoint in a board. The aim of pediatric behavioral testing is to determine, as accurately and reli able-bodied as executable, the presence and disposition of any hearing impairment and the threshold of hearing crossways the speech frequency range, from 500- 4000Hz. The choice of techniques is based on the developmental get on with, not necessarily the chronological age of the age. Behavioral testing should be accompanied by tympanometry, to investigate the status of the snapper ear. sorting can be divided into two let out but overlapping aras of auditory detection and auditory discrimination. diversity techniques cannot be incorporated into the assessment until the child is 18-24 months developmentally.

Distraction Test

By 6-7 months most babies are sufficiently mature to sit unsupported and are able to turn to locate quiet conk outs presented out of vision and level with the ear, provided they are not engrossed in other activities.

This is a sensitive and reliable test for detecting hearing damage in this age group, if administered by skilled, well trained testers.

Test Environment

The test should be carried out in a sound treated room or audiometric booth which is king-size enough to accommodate parent(s), child and 2 testers comfortably.
The room should be suitably furnished and free from unnecessary visual distractions. The soil noise should be as low as possible and ideally meet the requirements of ISO 8253-2 ( 1992).
