Abstract
Hearing aid device is a small electronic gadget that is fit in or behind the ear to improve one’s hearing and consequently communication ability.This research work involves the design and development of a hearing aid device withpre-amplifier; an acoustic signal picked-up using a condenser microphone. TDA 2822M IC is configured to produce an audio amplification which is converted to audio signal through a headphone. Designed equations were employed to calculate the physical parameters of the circuit. After the design, the circuit was constructed and tested on 4 people with partial hearing probl…
