There is sound in the tuning fork. You just have to put your ear drum directly on it.

It’s not actually sound. It’s vibration. Sound is a propagating wave. The fork oscillates and when you put your face on it you’ve given the vibrations a medium to propagate through. Even if you put your ear drum directly on the fork the vibration would cause the ear drum to oscillate and then a sound wave would form in your cochlea (inner ear).

I’m trying to make the distinction that it is not sound in a vibrating fork. The sound is what happens when the vibration of the fork is translated into a medium as a pressure wave. So there is no sound in the fork.
