Reproduction levels of outdoor soundscapes in the lab after in-situ exposure: participant responses and recording level envelopes

  • Supplemental material for https://doi.org/10.1051/aacus/2025062 To investigate loudness biases in the lab, where outdoor sounds are perceived as being too loud if reproduced with physically accurate levels in the lab, a listening experiment was conducted, where thirty-one participants visited a street and listened to the environmental sounds for one minute. These sounds were also recorded using a dummy head. Afterwards, participants listened to the recording in a quiet laboratory and adjusted its level as they remembered it. About half of the sample did this immediately, the other half about 20 min after the recording, during which the performed another listening tests. Afterwards, previous experience with acoustics, musical sophistication and noise sensitivity were assessed. The results revealed a mean gain adjustment of 8.9 dB below the original. The data uploaded here comprises participants gain adjustment, the recording levels averaged other A) the entire recording and B) theSupplemental material for https://doi.org/10.1051/aacus/2025062 To investigate loudness biases in the lab, where outdoor sounds are perceived as being too loud if reproduced with physically accurate levels in the lab, a listening experiment was conducted, where thirty-one participants visited a street and listened to the environmental sounds for one minute.

The data uploaded here comprises participants gain adjustment, the recording levels averaged other A) the entire recording and B) the first and last 7.5s or 15s, respecitvely and all questionnaire responses as well as aggregate scores for musical sophistication and noise sensitivity, as well as a binary categorization of the respondent into laymen and experienced, based on their previous experience with acoustics. For sociodemographic information, participants age, sex and educational degree are reported as well.
