✦ Synopsis

The results of extensive measurements made on 58 different models of European passenger cars are used to show the influence of speed and driving conditions on noise emission. The range of levels covered by different driving conditions around a speed of 50 km/h has median values of 66.4 to 79.5 dB(A). The spread in levels measured for all car models in any single driving condition is smaller than the spread due to different driving conditions.
