sound The decibel scale is logarithmic A 10 dB increase is a doubling of perceived loudness An increase from 50 db to 60 db is perceived as twice as loud An increase from 50 db to 70 db is perceived as four times as loud. PROPERTIES OF SOUND KEY POINTS Normal conversation, between two people, 1 meter apart is approximately
60 dB (measured at the source) Conversation at normal effort becomes difficult when the surrounding noise level rises to 66 dB At 2 meters apart, ambient noise at 60 dB is disruptive At 3 meters apart, ambient noise at 56 dB is disruptive. EPA Studies have shown that noise in excess of 40 dB can disturb sleep. PROPERTIES OF SOUND KEY POINTS
