Landscapes but not soundscapes are planned. Today’s noise control is based on traffic noise prognosis and is confined to average sound level of traffic noise. However, the heterogeneous soundscape embraces many component sounds, background sound inclusive. Prognostic design tools are needed by which “quiet” and pleasing soundscapes can be ensured. In a psychoacoustic experiment, promising properties of soundscapes were retrieved from similarities among evolutionary spectra. These were meaningfully differentiated in accord with features of perceived soundscapes extracted by multi-dimensional scaling: (a) position and slope of loudness functions due to qualitative differences (road-traffic exposed or shielded sides of buildings), (b) clusters of shielded soundscapes relative to two types of sound-exposed soundscapes, and (c) relative contribution of direct sound to background in soundscapes. The dualistic similarity approach conveys useful knowledge for soundscape design and mitigation psychophysics.
