Various indices have been proposed in the literature to achieve this purpose. However, many of these methods necessitate specialized equipment or extensive data collection. This study introduces an enhanced predictor for dwelling acoustic comfort, utilizing cost-effective data consisting of a 30-s audio clip and location information. The proposed predictor incorporates two rating systems: a binary evaluation and an acoustic comfort index called ACI. The training and evaluation data are obtained from the \u201cSons al Balc\u00f3\u201d citizen science project. To characterize the sound events, gammatone cepstral coefficients are used for automatic sound event detection with a convolutional neural network. To enhance the predictor\u2019s performance, this study proposes incorporating objective noise levels from public IoT-based wireless acoustic sensor networks, particularly in densely populated areas like Barcelona. The results indicate that adding noise levels from a public network successfully enhances the accuracy of the acoustic comfort prediction for both rating systems, reaching up to 85% accuracy.<\/jats:p>","DOI":"10.3390\/s24134400","type":"journal-article","created":{"date-parts":[[2024,7,8]],"date-time":"2024-07-08T09:01:19Z","timestamp":1720429279000},"page":"4400","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Acoustic Comfort Prediction: Integrating Sound Event Detection and Noise Levels from a Wireless Acoustic Sensor Network"],"prefix":"10.3390","volume":"24","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7362-199X","authenticated-orcid":false,"given":"Daniel","family":"Bonet-Sol\u00e0","sequence":"first","affiliation":[{"name":"HER\u2014Human-Environment Research, La Salle Campus Barcelona\u2014Universitat Ramon Llull, Sant Joan de la Salle, 42, 08022 Barcelona, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4265-2985","authenticated-orcid":false,"given":"Ester","family":"Vida\u00f1a-Vila","sequence":"additional","affiliation":[{"name":"HER\u2014Human-Environment Research, La Salle Campus Barcelona\u2014Universitat Ramon Llull, Sant Joan de la Salle, 42, 08022 Barcelona, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2261-5471","authenticated-orcid":false,"given":"Rosa Ma","family":"Alsina-Pag\u00e8s","sequence":"additional","affiliation":[{"name":"HER\u2014Human-Environment Research, La Salle Campus Barcelona\u2014Universitat Ramon Llull, Sant Joan de la Salle, 42, 08022 Barcelona, Spain"}]}],"member":"1968","published-online":{"date-parts":[[2024,7,7]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"65","DOI":"10.1016\/j.landurbplan.2016.02.001","article-title":"Soundscape descriptors and a conceptual framework for developing predictive soundscape models","volume":"149","author":"Aletta","year":"2016","journal-title":"Landsc.
