MEASURED VARIATIONS IN AIRCRAFT NOISE NEAR ARLANDA AIRPORT

Tape recordings were made of ca 1,500 takeoffs at Arlanda Airport by means of an automatically operating recording device. Type of aircraft and destination as well as temperature, air humidity and wind velocity, and direction were registered. Correlation analyses of peak sound levels in dB4 and meteorological factors were made. Sound level showed no significant covariation with humidity and temperature, but a positive correlation to the wind velocity from the aircraft towards the measuring station was found. The mean values measured verify theoretical calculation of the sound level from standard noise contours according to ISO Recommendation No. 507 and NASA CR-767 and also show that calculations are more accurate than occasional measurements. Parts of the data were also analyzed as to the difference among dB4, PNdB, EPNdB, and dBD. High correlations among these different units were found.
