The Rechargeable In-the-Ear (ITE) hearing Aids SM61 are primarily comprised of a microphone, integrated circuit, and a speaker. The microphone plays a crucial role in capturing and converting external sound waves into electrical signals.
The electrical signals are then transmitted to the integrated circuit which amplifies the signal to an appropriate level. The integrated circuit is responsible for processing and performing various adjustments to ensure optimal sound quality.
Finally, the amplified electrical signal is converted back to sound by the speaker, also known as a horn, to allow for the amplification and restoration of sound. This sophisticated system ensures that the wearer receives clear and amplified sound, improving their ability to communicate effectively and enjoy their surroundings.
