A musician beats a drum gently at first, and then hits the same drum head much harder. How do the sound waves change when the drum is hit harder?
Pitch increases, loudness stays the same
Loudness increases, pitch stays the same
Both loudness and pitch increase equally
Loudness decreases, pitch increases
Solution
Striking the drum harder increases the amplitude of vibration, which increases loudness, but it does not alter the fundamental frequency or pitch of the drum membrane.
