"Force is a wave" is not correct. Some forces may appear as waves, but not all. Any periodic movement can produce a sound. If the movement has a frequency somewhere between about 20 and 20,000 Hz (it repeats 20 to 20,000 times per second), then the sound will be audible for humans.
Sounds which the human ear can detect are caused by the movement of air. In a vacuum, air does not exist, therefore nothing defined as "sound" can exist. And example of sound is the clapping of two hands. The sound is created by the rapid movement of air from between the palms when clapping. If no air moves, then no sound is created. You may clap your hands in a vacuum and no sound will be emitted because a vacuum may be described as the absence of air.
