• The representative spectrum of traffic noise is expressed in terms of the normalized A-weighted sound pressure level, δL_n. Assuming that the traffic noise annoyance is measured by the time-average sound level, the dependence ofδL_n upon the traffic speed and the percentage of heavy vehicles has been derived. For traffic without heavy vehicles, an increase in traffic speed causesδL_n to decrease at low frequencies. The presence of heavy vehicles destroys the dependence of δL_n upon the traffic speed and may increase the value of δL_n a few decibels at low frequencies.
