Шум стройплощадок

Шум стройплощадок

Abstract

Construction is a source of high intensity (75-90 dBA) acoustical pollution in cities. It is found out that a construction site noise depends on the character of construction works. A classification of building sites on noise levels was proposed (5 classes). Corrections to equivalent sound level for the spectral analysis of construction sites were obtained. Dependencies of noise attenuation of area sources with the increase of distance were investigated with theoretical and practical methods. Processes of construction site noise levels’ alteration during their functioning were examined.

Строительство является источником высокоинтенсивного (75-90 дБА) акустического загрязнения в городах. Установлено, что шум стройплощадки зависит от характера выполняемых строительных работ. Предложена классификация стройплощадок по шуму всего 5 классов. Получены поправки к эквивалентному УЗ для спектральной оценки стройплощадок. Теоретически и экспериментально исследованы зависимости от пространственных источников стройплощадок с увеличением расстояния. Рассмотрены процессы изменения шума стройплощадок в процессе их функционирования.
