Aircraft type, destination, temperature, humidity, wind velocity and wind direction were recorded automatically for about 1500 takeoffs. Peak sound levels in dBA showed no significant correlation with humidity or temperature, but there was a positive correlation with the wind velocity from the aircraft to the measuring point. Theoretical calculations according to ISO Recommendation No. 507 and NASA CR-767 were verified, and high correlation between units was found when parts of the data were analysed for the differences among dBA, PNdB, EPNdB and dBD.
