NOISE PERCEPTION, PSYCHOACOUSTIC INDICATORS, AND TRAFFIC NOISE

We present an overview of sound characteristics, no ise and noise perception. Several sound measures, weightings and psychoacoustic parameters are discussed and compared. Finally, we present some data comparing several psychoacoustic measures and their predictability of traffic noise annoyance and vehicle detection. We propose loudness measures according to Zwicker as a standard for environmental noise assessment, in detriment of the widely accepted A-weighted Leq.
