Acoustically effective façades design by Jochen Krimm

///Acoustically effective façades design by Jochen Krimm

The silhouettes of the great European metropolises are characterized by a high density of high-rise facades made of glass, metal or stone. On one hand, this density stands for economic power and good employment values. On the other hand, the large sound-reflecting surfaces in the cities are responsible for an increase in sound pollution in their vicinity. They cause the most frequent inner-city sound source, traffic noise, to double in perceived intensity. Direct sound and reflected sound add up in the urban environment. This effect of sound level increase through reflection has been subject of acoustic research for some time. In architecture, however, the topic of noise reflection has been completely neglected. This Ph.D. elaborates the theme, it´s acoustical effects and suggests a methodology to handle them in an urban environment.
