Find out what the variation in traffic day and night means to the traffic noise: high traffic intensity in the daytime and less in the night.

In general, traffic noise is quantified in decibels (dB) and is referred to as a yearly average over 24 hours. But the noise level fluctuates significantly during the time of day. In these examples you can hear the variations. During the daytime, the traffic flow is much higher – effecting the noise significantly – than during the evening, and especially nighttime.
