Abstract
Sound quality was approved in Ecocity World Summit 2019 to be developed as a bio-geophysical indicator. The classical measures of sound pressure level are not sufficient to quantify healthy noise levels and balanced soundscapes. Additional acoustic indicators relating sound to perception were investigated for potential indicators of Sound Quality including balanced soundscape (normalized difference soundscape index and biophony / anthrophony ratio), psychoacoustical annoyance, temporal sound level variance, and spectra gravity center. The Olympic Village, Vancouver, BC was used as a proxy neighborhood to represent Ecocity fractal. ISO 12913-1-3: Soundscape standard was applied for collecting and analyzing data. The method of triangulation analysed acoustic measurements of 38 data measurement locations, 71 survey responses and taxonomy classification supports the evidence that psychoacoustic annoyance is an appropriate indicator for the Sound Quality benchmark standard in the Ecocity framework.,Spectral gravity center,Ecocity,Sound quality,Balanced soundscape,Psychoacoustical annoyance,Sensory pleasantness,Temporal sound level variance
