Semi-continuous noise sources • Up to 50-55 dB(A) is acceptable • “Learning problems arise when noise is 60 dB(A) or more” • “New schools should not be planned close to existing airports”
Intermittent noise sources • Most policies are based on sleep awakening for adults • No real data/research for young infants
Air, Rail and Road traffic noise covered by Standards and Guidelines.
