The practicalities of soundscape data collection by systematic approach according to ISO 12913-2

Arup has developed, formalised and digitised an approach to performing soundscape data collection. The approach is centred on the ISO 12913-2:2018 Technical Standard which proposes a standardised method for soundscape data collection that includes 3D sound recordings, measurements of acoustic and psychoacoustic parameters and provides example questionnaires for subjective perception. While ISO 12913-2 describes procedures for how recordings, measurements, and interviews are to be carried out, much of the Standard is informative only. A structured format has specifically been developed to further standardise an approach and understand how it may be implemented effectively within a corporate acoustic consulting environment. This study discusses findings and conclusions gathered from undertaking soundscape surveys using the structured approach at seven purposely selected urban centres across the world. Further development has been made on how to interpret and implement the ISO 12913-2 Standard to facilitate and make accessible for use within the corporate consulting environment. Conclusions have been drawn from the issues faced and recommendations for further consideration provided that are based on correlations in the data set obtained through the surveys.
