Схема слухового аппарата, микрофонного усилителя на 3-х транзисторах с пояснением принципа действия

In this video, I present a fairly good, high-quality microphone amplifier circuit that can be used as a regular hearing aid. This circuit is built using just three bipolar transistors. It has high sensitivity, which can be adjusted. This circuit is powered by 3 volts, and the amplifier consumes only a few milliamps, which is quite energy-efficient and low. The output sound is also quite high-quality and clear. In the video itself, I explain how this microphone amplifier circuit works.
