In October 2015 the city of Antwerp has, as part of their traffic noise action plan, constructed two test sites in an urban environment where five different thin noise reducing asphalt layers (TAL) and a poroelastic road surface (PERS) are compared to the standard Stone Mastic Asphalt 10 (SMA - 10). The mechanical and acoustical characteristics of all these test tracks will be monitored twice a year for at least three years. Furthermore, the objective noise reduction is compared to the subjective perception of the residents living nearby using a pre- and post-survey. In this paper the objective noise reduction is compared with self-reported physical complaints, which were assessed in the pre- and post-survey. From the objective results a noticeable reduction in road traffic noise can be observed, ranging from 3.8 to 5.2 dB(A). No clear changes could be found in the self-reported physical complaints, although the overall disturbance from road traffic noise has been reduced. |
