In 1920, vacuum tube listening devices were developed, allowing audios to be become electronic signals, these signals were after that amplified for the individual. Norman Krim, an engineer at Raytheon and also the inventor of the previous subminiature vacuum tube innovation, saw the potential application for transistors in listening devices. The transistor not only made it possible for listening device to be made smaller; they can ultimately be used either entirely inside or behind the ear.

These are all things that would certainly later on be crucial in the production of the initial real listening device a couple of years later on. High-speed cpus and microcomputers were created in the 1980s. The very first all-digital hearing aids were produced in the 1990s.
