Assessment of Uncertainty in Urban Traffic Noise Measurements

This paper presents measurement results recorded by noise and traffic volume monitoring station located in Krakowska Street, Kielce. Poland. The measurements were performed in the period from January to December 2013, twenty-four hours a day and with a sampling time of 1 minute. The results were subjected to statistical analysis. A type A uncertainty was evaluated. A new parameter COVL Aeq was proposed for variability assessment of the equivalent sound pressure level.
