## 3 Techniques for Field Data Collection
### Questionnaire Surveys  
As stated above, the questionnaire is primarily based on Method A of ISO/TS 12913-2:2018. This method begins with a set of questions relating to the sound environment which are assessed on a 5-point Likert scale, coded from 1 to 5. A sample codebook to demonstrate the recommended variable naming and response coding is included in Appendix D.

These taxonomic categories of environmental sounds are based on the work done by [PERSON] [44] and [PERSON], [PERSON], and [PERSON] [45]. Next are the 8 scales which make up the circumplex model of the Swedish Soundscape Protocol [46], describing the Perceived Affective Quality (PAQ). These are assessed on a 5-point Likert scale from 'Strongly Disagree (1)' to 'Strongly Agree (5)'. These are included as follows: Pleasant, Chaotic, vibrant, Uneventful, Calm, Annoying, Eventful, and Monotonous (labeled PAQ01 through PAQ08, respectively). Following this are five questions addressing the participant's overall assessment of the surrounding sound environment, addressing overall acoustic quality, the appropriateness of the sound environment to the location, perceived loudness, and how often the participant visits the place and how often they would like to visit again (labeled SSS01 through SSS05, respectively). The fourth section comprises the WHO-5 well-being index, asking how the participants have been feeling over the last two weeks, such as 'I have felt calm and relaxed'.
