Sound - Sound intensity - Episode 207



School Noise
Investigate loud sounds in your school. Your own hands can be your loudness meter! Make a soft shooshing sound by gently rubbing your palms together. Snap your fingers. Clap your hands. These are your reference sounds. Go to different parts of the school and make these three sounds. If you can hear the shooshing, that place is quiet. If you can't hear the shooshing, but can hear the fingersnaps, that place is moderately loud. If you can't hear fingersnaps but can hear clapping, the place is loud. If you can't hear clapping, the place is DANGEROUSLY LOUD… you need ear protection!
