An elderly retired gentleman had had severe hearing problems for some time.
He went to the doctor and the doctor was able to have him fitted for a set of hearing aids that allowed the man to hear better than he had ever heard before.
One month later, the elderly man went back again to the doctor. The doctor said, "Your hearing is perfect. Your family must be really pleased that you can hear again."
The gentleman said, "Oh, I haven't told my family yet. I just sit around and listen to the conversations. I've changed my will three times!"

Transistor hearing aid

In 1952, the first transistor hearing aid went on sale, the model 1010 manufactured by the Sonotone Corporation in Elmsford, NY, U.S. It weighed 3.5-oz, measured 3"x1.5"x0.6" and cost $229.50 (about $1500.00 today). It was a hybrid device consisting of two sub miniature pre-amplifier tubes and a single transistor as the final audio amplifier to benefit from the low power consumption of transistors. The reason for the hybrid design was that the first junction transistors had signal to noise ratios which were inferior to tubes. Within months, transistor production techniques were improved largely eliminating noise, so the hybrid model was shortly discontinued.
