Find the best control: to compare loudness, what must stay the same besides hit strength?
Find the best control: to compare loudness, what must stay the same besides hit strength?
Tap to reveal answer
Use the same object and same place to hit each time. Consistency in method ensures only hit strength affects the sound.
