The aim of this article is to describe the state of the acoustic climate at the rest and service areas (MOPs) situated by A4 motorway in Silesia The analysis includes the research results conducted at these parking lots from May till August 2010. The research was conducted with the digital noise meter, which was connected with the computer during measurement. The research results indicate the essential differences in the noise intensity between the particular rest and service area reaching up to 12 dB(A), in spite of the similar value of the traffic noise in all of the places where the research was conducted. It was assumed that the level of noise on each of the parking lots should be similar to standing norms for the recreation areas i.e. below 55 dB(A). The research conducted at 4 MOPs indicated that only at two of them, MOP Halemba and Wirek, these norms are fulfilled. The lack of the proper anti-noise protection in the form of the sound absorbing screens at the parking lots situated by the motorway causes the situation in which the level of noise at the places devoted to rest highly decreases the possibility to relax before the next stage of a journey.
