Why do people's evaluations of environmental noise differ so widely, given equal acoustics (decibel level, noise source type)? Non-acoustical factors, such as perceived control and noise sensitivity have been suggested to explain the diversity in reactions to noise, and have proven to do so in mostly correlational studies. For noise with a human origin (e.g. aircraft noise) the social context of exposure seems worthwhile to be considered too as a determinant of noise annoyance. An experiment testing this hypothesis was conducted. The effect of social context, manipulated in line with findings from Social Justice Theory (e.g. Tyler, 2000), on the evaluation of different sound pressure levels (Aircraft noise, 50 vs. 70 dB(A) eq.) was assessed. Findings show significantly more annoyance with higher sound pressure level. In the socially just context, where subjects were let to believe they had been participating in decision making, no significant main effect of sound pressure level was found.
