Abstract

The Positive Soundscape Project is a large multi-disciplinary project investigating the perception of soundscapes. Recent findings indicate that speech communication is a principal factor in users’ perceptions of urban soundscapes. The project has therefore explored how this factor might be quantified. This paper reports on an attempt to use speech intelligibility index (SII) to characterise time-varying speech intelligibility in real outdoor soundscapes. The relationships between SII, subjective intelligibility and subjective quality were explored, as functions of signal-to-noise ratio. Possible applications in sound quality mapping of soundscapes and potential implications for rational planning of soundscapes are discussed.
