π Loudness and Sound Intensity
Explore the science of loudness and sound intensity in this Grade 4 physics quiz. Learn how vibrations create sound, how amplitude affects loudness, and why protecting our hearing from loud noises matters. **What you'll learn:** - Loudness is a measure of sound intensity related to vibration amplitude - Larger vibrations produce louder sounds - Different environments have different noise levels - Safe listening practices protect our hearing
