Finally, drum sound is impacted by the way that the drum is struck. If it is struck with an open hand or wooden stick, it makes a sharp noise instantly, followed by a vibrating sound. If struck by a padded mallet, the drum will make the vibrating noise the entire time. Drums are one of the oldest instruments known to humans.
