Design an Electronic Amplifier Circuit for Hearing Impaired
Abstract
Low-cost hearing aid device was designed and constructed to produce an amplified sound for people with hearing loss. A 3V DC was used as the power supply. The condenser microphone was used as input transducer to pick up sound from the environment for conversion to electrical signal, npn transistor (BC337) along with tow capacitors and three resistors were used as pre-amplifier.to amplify. The integrated circuit available in 8-pin mini chip package and specially designed for portable power amplification was used for the amplification function a 32 ohms ear phone was used as the output transducer to convert the amplified electricáksignals back to sound.
