Hearing Aids
... • In 1952 the first hearing aid with an on/off switch was created. This new model was known as a transistor hearing aid • In the 1990’s digital hearing aids were created allowing clearer and better hearing for the user • 2000s- much smaller hearing aids were produced and are barely visible on the us ...
