2. What is the year of first electric hearing aid introduction?1898
3. What did the earliest hearing aids look like?The first hearing aids were big horn-shaped devices made from metal, wood, or animal horns. They helped people hear by funneling sound into the ear, but they couldn't pick out quiet sounds or reduce background noise.
4. How did hearing aids become smaller and smarter?When the telephone was invented, scientists learned how to use electricity to amplify sound. This led to the first electric hearing aids around 1898, which were still big but much louder and clearer.

Acoustic Amplification: The process of making sounds louder using physical shapes and structures, common in early hearing aids.
Electrical Amplification: The process of making sounds louder using electronic components, a significant step in hearing aid technology.
Receiver (Speaker): The component in a hearing aid that delivers the amplified and processed sound directly into the user's ear canal.
