Vol 1: the procedure which was adopted to investigate the community response to combined noise from aircraft and road traffic is described. A social survey was conducted at 9 sites at 3 levels of aircraft and traffic noise with 35 interviews per site. The mean results without regard to traffic noise level show good agreement with previous data, but there are significant variations with respect to traffic noise level. The use of the noise pollution level concept, which describes the noise climate as a function of mean energy level and the standard deviation of sound level, leads to strong correlation and median dissatisfaction with the total noise environment. Vol 2: the results of a social survey designed to investigate the influence of background (road traffic) noise on annoyance due to aircraft noise, and on general dissatisfaction with the total noise environment are presented. Nine sites with 3 aircraft and 3 traffic conditions were selected and 35 people per site interviewed. The regression lines for site mean aircraft annoyance scores (Guttman Scale) for each traffic condition show that the same annoyance score is achieved at an aircraft exposure 10 nni lower, when traffic is reduced from heavy to access only. The general noise dissatisfaction shows an increase with traffic at low nni, but a decrease at high nni. The use of the noise pollution level unit satisfactorily explains this result, increasing the correlation coefficient for the grouped data from 0.94 against nni to 0.96.
