7 BABY HEARING TROUBLE INSPECTIONS

Disparity or hearing trouble of the baby determined with a few inspections matching with its age
1. Otto Acoustic Emission
Inspection: in baby’s ear placed by an ear cave cork (probe) made from rubber substance which in it there are microphone and loudspeaker, what circuit with cable to recorder. It can be used since the baby is 2 days old.
Utilize: to know whether snail house (cochlea) function well.
2. Noise Maker
Inspection: with electronic appliance which can voice by the certain force and frequency.
Utilize: to perceive child reaction to given voice stimulus.
3. Behavioral Observation Audiometric (BOA)
Inspection: perception to behavioral response that have the character of reflex. The examples of response perceived are blinking eye, widening eye, wrinkling face, stop sucking milk, and its heartbeat mount. Inspection by this appliance assisted the audiometer functioning to measure hearing sill.
