Serviaudifono Circuit Diagram Low-cost hearing aid circuit. The circuit can be easily assembled on a small, general-purpose PCB or a Vero board. It operates off a 3V DC supply. For this, you may use two small 1.5V cells. Keep switch S to 'off' state when the circuit is not in use. To increase the sensitivity of the condenser microphone, house it inside a small tube.

Circuit diagram. Parts: R1 = 2.2K R2 = 680K R3 = 3.3k R4 = 220K R5 = 1.5K
Hearing Aid circuit diagram and instructions
The audio output of this aid circuit is 10 to 15 mW and the quiescent current drain is below 1 mA. The circuit can be easily assembled on a veroboard. For easy assembling and maintenance, use an 8-pin DIP IC socket for TDA2822M. Schematic of Hearing Aid Circuit By using capacitor C7, it lowers the gain in the high-frequency band.T to keep the circuit stable while reducing noise, Headphones are directly linked to the power supply and get the audio signal from the collector. Thus, the headphone is a load of this circuit. Application Uses. Hearing aid devices.
