Working Principle Of Behind-the-ear Hearing Aids

Sound reception and conversion: The microphone receives external sound signals and converts them into electrical signals.
Signal amplification: The amplifier amplifies the received electrical signals to ensure that the sound is loud enough for the user to hear.
Sound output: The receiver converts the amplified electrical signal back into sound and transmits it to the user's ears through the sound-conducting ear hook and plastic tube.
Personalized adjustment: Users can adjust the volume and tone knobs to make personalized adjustments according to their personal hearing conditions to obtain the best hearing effect.
