abstract = "Estimation of the day-evening-night level, Lden, requires either measurements of the A-weighted short term average sound level, LAeqτ (road traffic noise), or measurements of the sound exposure level LAE (aircraft and train noise ). Four classes of meteorological conditions are considered. The random nature of noise emission and propagation is a source of error in Lden estimation. Standard deviation of the day-evening-night level, σden, is proposed as a measure of this error.",
