[Statistical studies of street traffic noise in the city of Pescara, based on findings on 24-hour periods].
The level of acoustic pollution from road traffic in Pescara has been measured in 10 residential areas with commercial activity. Measurements have been carried out during 24 hours, by means of a magnetic recorder Nagra IV-SJ, joined with a statistic level analyzer Brüel & Kjaer 2312 in connection with an alpha digital printer. Cumulative statistic levels, standard deviation, equivalent level, noise pollution level and traffic noise index, have been calculated. Composite indexes of acoustic pollution expressed as equivalent level 24 hours (Leq 24), level day-night (Ldn) and composite noise equivalent level (CNEL) have been calculated elaborating the data obtained. All collected data resulted to exceed the limits of stated rules.
