Sound predictions in an urban context

Recent studies show that environmental noise in urban environments continues to be a great health risk. This is especially further transmitted by the hard materials are mostly used for façades. To predict these effects it desirable have reliable prediction method. There already several ways sound levels an context. paper investigates two while focusing specifically on practical approach methods suitable use during actual design project. The impact of changing façade at specific location investigated using both methods. A which reflects where has smaller impact, absorbing façade, and combines taken into consideration. These adaptions potential improve area from 1.7 up 9.3 dB(A).
