IMPACT OF SIMPLE EAR-HEARING AID DURING COVID 19 ERA


The ear is one of the most important sense organs which alerts one to changes that cannot be easily seen. For most animals it is early warming organ controlled by instinct, while for humans it is inevitable for effective communication. A hearing aid is electronic battery-operated device that amplifies and enhances sounds to allow for improved communication. Every conventional hearing aid has mainly three parts; a microphone used to collect the sound and convert into electrical impulse, an amplifier which modulate the electrical impulse making sounds louder and a speaker that converts amplified signal into sounds and feeds them into the ear. The main objective of this research is to implement a simple hearing aid using locally available materials and components. It improve the input state, pre-amplification stage, power amplification stage, output stage and power supply in order to determine the functionality and adaptability of the system. Keywords: Microphone, earpiece, regulator, condenser etc.
