Abstract:
This paper examines the use of mobile LSW on inner-city construction sites. At the beginning, the basics of sound generation, propagation and perception are given. Building on this, both stationary and mobile LSW are analysed, whereby the various construction methods and the basic functionality of these are presented. Mobile LSW are suitable for use on construction sites as they are less expensive than stationary LSW, require less effort to set up and are not tied to a specific location. The special feature of construction noise is that it results from many different noise sources that are located and move throughout the construction site. Depending on the type of construction site, the equipment used and the areas to be protected, the type, material and arrangement of the mobile noise barriers must be designed and adapted. However, complete protection against construction site noise can never be realised in practice. In order to investigate the effect of mobile LSW, noise measurements were carried out at four measuring points on a construction site for the ‘Dresden Central Station’ project, noise measurements were carried out at four measuring points. These were located in front of, next to and behind the LSW. By comparing different parameters of the measured sound, it was found that the use of these mobile noise barriers leads to a noticeable reduction in noise pollution. Complete protection of the residential building was not possible, as the dimensions of the LSW were limited due to lack of space. Mobile noise barriers are a good and cost-effective method of reducing the impact on neighbouring residents. Their use should always be considered wherever possible.
