Sound is Vibration

A person banging on a drum at a Gallaudet football practice.


I was telling some friends the other day: sound is vibration. Your ears pick up sound because it’s a specific type of vibration. But, there are other ways of “hearing”.

Many schools for the deaf bang on a drum to signify the end of a play or a touchdown. Gallaudet no longer uses their drum except at practice as shown above.
