Measurements of the street traffic noise - equivalent noise level A characteristic and noise in standardized octaves
Typically, the noise level is measured and regulated by 1.2-1.5 m a7.5 m from the first transport belt. Need to know the parameters in both directions:
The percentage of trucks and heavy transport in the traffic flow (()
