Noise Map of Helsinki

In this map the noise levels of road traffic are in LAEQ,22-07.00 hrs and the airport contours are in Lden (different greenish colours).

This map is sort of home made from various parts. Only the MAIN roads are shown; experts say that between the main roads levels are mostly above LAeq=55 dB(A) (as a casual visitor I find that hard to believe).
