Abstract

Hearing is one of the five senses, therefore, it is very important that the human ear be able to detect sound in the audible frequency range. However, in some cases, certain individuals have difficulty hearing in either or both ears. It is therefore necessary that a device that can help in correcting this be developed. In this work, a hearing aid has been constructed using readily available circuit components (transistors, capacitors, ICs). This makes the device easily accessible and affordable for anyone who needs it. The hearing aid constructed was tested under different levels of ambient noise and was found to amplify the desired sound while filtering away the noise. Hence, it can be said to function considerably well.
