Yes.

By definition, sound is: "mechanical vibrations transmitted through an elastic medium" (dictionary.com). Noise doesn't need to be perceived to be defined as "sound" since it is a mechanical entity.

However

The existence of the sound cannot be categorically proven unless heard (observed) or recorded, even though under the usual physical laws, it would be expected to occur.

Yes, the leaf would still create sound waves as it falls, regardless of whether there is someone present to hear it or not. Sound is a physical phenomenon that occurs when an object vibrates in a medium like air.
