Abstract

One of the biggest problems of traffic noise protection is the proper design of noise barriers, their location, length and height. An experimental and analytical efficiency method of traffic noise protection against traffic noise, in the case of a single-family building, has been presented in this paper. The efficiency of this screen has been evaluated by an indirect method. In this case research survey on site has been made. The calculations have been made with the use of three methods. The results of measurements and calculations have been compared. A low efficiency acoustic screen has been demonstrated, whereas its low efficiency mainly resulted from the low height and length. On the basis of the interviews with residents, it can be said that the construction of screens, even those of low efficiency, makes sense.
