Reduced reproduction levels of outdoor soundscapes are deemed appropriate - even after real-world exposure Markus von Berg, Siegbert Versümer, Joshua Bitta and Jochen Steffens. Supplemental Material for https://doi.org/10.1051/aacus/2025062 The supplemental material consists of two types of data: participants’ responses including aggregated levels and loudness measures (1) and level envelope for each participants’ individual recording (2).

[email protected] 1. Participants responses The CSV-file data_questionnaires_aggregateLevels.csv contains a table with participants' responses to the questionnaire and all aggregate level measures (LAeq, LLz, etc.) discussed in the paper. For LAeq and LLz, both left (L) and right channel (R). For the LLz of the first and last 7.5s and 15s, respectively, only the maximum values were assessed. participant break_inBetween adjusted_level_difference LAeq_L … 1 immediate -8.9 77.88 … 2 after break -7.6 78.26 … 3 immediate -9.6 76.67 … … … … … … Schematic view of the response table A full list of the column names and their meanings is listed the end of this documentation. For the questionnaires Gold-MSI and NoiSeQ-R, composite scores as well as single item responses are provided. Items that were reversed for score aggregation are marked with and "R" at the end of the column name. For information on the item prompts and the response labels, please refer to Schütte et al. (2009) for the NoiSeQ-R, and Müllensiefen et al. (2014) for the Gold-MSI. To see the questions and response options for the experience with acoustics, please see the supplemental material of von Berg et al. (2021).
2. Level envelopes The archive file level_envelopes.zip contains 31 CSV-files level_envelope_participant[id].csv that include unweighted and Aweighted levels of the 1-minute recordings with a resolution of 125ms for each participant. The two channels of each envelope correspond to the left (L) and right (R) ear of the dummy head. For participant 25, the data misses a few seconds due to a technical issue during the recording. The values are rounded to three decimal points.
