Sound waves are made by a vibrating object. The object turns other forms of energy, e.g. electric or kinetic energy into sound waves. This happens when the object vibrates the air molecules around it, which are then transferred as sound. A tuning fork moves back and forth at a specific frequency thus moving the air around it in the same frequency which then reaches our ears as sound waves. So if there are no ears to hear then there are only vibrations!

"...the moral test of government is how that government treats those who are in the dawn of life, the children; those who are in the twilight of life, the elderly; those who are in the shadows of life; the sick, the needy and the handicapped. " ~ Last Speech of Hubert H. Humphrey "A nation's greatness is measured by how it treats its weakest members." ~ Mahatma Ghandi
