Would there be sound without friction?

Every time you talk. Sure, the air from your lungs pushes on your vocal cords, but they're basically frictionless. Steady pressure from your lungs is modulated by differences in vocal cord tension, and combines with changes in the shape of the oro-lingual cavity (your mouth) to create sound. No friction required.

I know what you are thinking, but YES there would be sound without friction. All that is needed to make sound is to move molecules in some direction. read more

Quick Answer. Without friction, energy transfer would be easier and stopping motion would be more difficult. If there was no friction, there would be no force slowing down motion when two objects rubbed against one another. read more

Yes. Sound has to do with vibrations. Many times, friction causes vibrations, but there is no absolute necessity of friction for producing sound. A loudspeaker for example, is a vibrating structure. Friction and absorbing properties may improve a loudspeaker, but this is all. read more

In these cases, a world without friction would essentially be similar to living in a world of completely 100% frictionless ice, where if you attempt to walk, since there would be no friction pressing against your shoe causing you to be able to take another step. read more
