Govt teacher develops safety cap for hearing impaired people in Khammam

A government teacher with hearing impairment and known for developing innovative gadgets has made a safety cap that helps people with complete hearing loss by detecting sounds and alerting them to avoid possible danger.

The sensing mechanism in the cap detects sounds with an intensity of more than 75 decibels and warns the wearer through a vibration mechanism fitted in the



cap. 

It is helpful for elderly or medically impaired people whose hearing ability decreases with age to be safe on roads and in public places. 

Explaining the functioning of the safety cap, the teacher, Shaik Rajalipasha, informed media that a microphone installed in the hat receives sound waves from the surroundings and converts those waves into electrical signals.
