When the recent terrorist attack occurred in Manchester Arena, I was awoken by the screaming i Thats about the same as the lowest pedal on a pipe organ. In contrast, for lower decibel levels, we can distinguish sounds of the same intensity at different distances (the best distance is up to 100cm). WebThe 6 dB rule states that whenever the distance that separates you from the sound source doubles (e.g., you move from 100 to 200 feet away from the source), the sound decreases by 6 dB.
