Abstract :
Music players connected through ear hearing aids are popular among teenagers for listening to music. Listening to music using earphones for more than 2 hours a day can cause hearing loss and the risk of hearing loss. In addition, hearing loss is also caused by old age. Patients with hearing loss generally have difficulty listening to other people's words or voices that are too small, either in crowded or noisy places or difficulty listening to certain frequency ranges. So to overcome this problem, hearing aids were made. Hearing aids are made using analog components with a series of tools including a power supply circuit and a charge circuit, a mic-condenser sensor amplifier circuit, a band pass filter circuit, and a power amplifier circuit. The general working principle is: the mic-condenser output will provide input to the mic-condenser sensor amplifier circuit which will be amplified. Furthermore, the voltage is filtered by a band pass filter circuit. Then, amplified again by a series of power amplifiers and the sound can be heard through the earphones. After measuring, each measurement is still within the tolerance value, especially for power amplifiers, the percentage error value is 1.5%, so that hearing aids can work properly
