🕰 Evolution of Hearing Aids – From Trumpets to Technology
🎺 17th Century: Ear Trumpets – The Beginning
Developed in the 1600s, these pre-electric devices channeled sound through large horn-like tubes. Though basic, they laid the foundation for modern hearing care.
🔊 Pre-Electric Era: Acoustic Hearing Aids
Bulky and inefficient, early acoustic models passively funneled sound directly into the ear. They were the best options before electricity was harnessed.
⚡ 1900–1939: Carbon Hearing Aids
Powered by carbon microphones, these were the first electronic hearing aids—though large and noisy, they marked a turning point in amplification tech.
📻 1921–1952: Vacuum Tube Devices
Using vacuum tubes for signal control, these improved sound quality but required a heavy tabletop unit to operate.
📱 1952–1970s: Transistor Revolution
The invention of transistors made hearing aids portable, compact, and more user-friendly—ushering in a new era of accessibility.
💡 Late 1990s – Today: Digital Hearing Aids
