Transistors were instrumental in the sad demise of the good old fashioned hearing aid trumpet.
Great-Great-Grandad, would just say Eh! What! He would get very annoyed and ask you to speak up!
Great-Grandad used a trumpet to magnify the sound. This was not a very effective alternative, but very picturesque.
Grandad used a transistor powered hearing aid that was strapped to his body. This would greatly amplify the sound.
Dad uses a digital hearing aid that is almost invisible.
I am on the list for a Cochlea operation.
We have come a long way since the transistor revolutionised hearing ability.
