Drumming

Like a sound wave, the waves produced by drums are longitudinal. The vibration produced when a drum is hit creates pressure waves in the air. These pressure waves describe the sound. The more the drum head bends, the volume of sound increases, a higher frequency is created and the amplitude if affected. Pitches of drums range from low frequency basses to high frequency pitches. Like a speaker which amplifies sound through the air, noise from the drums travel to our ears because of the sound vibrations and type of waves. When the vibrating drum vibrates the air molecules around it, it does so at the same frequency to produce a beautiful sound.
