Abstract

Soundscape methodologies are increasingly recognised as effective approaches to address noise-related challenges. This study presents a bibliometric analysis of soundscape research focusing on the emerging domain of indoor soundscapes. Data were retrieved from the Scopus database using the keywords: “noise” AND (“noise barrier*” OR “noise control*” OR “noise reduction”) AND “soundscape”. After applying inclusion and exclusion criteria, 188 documents were selected for analysis, which included trend analysis, keyword co-occurrence mapping using VOSviewer (v1.16.19), and distribution analysis of indoor soundscape studies across different settings. Results show a notable growth in publication activity beginning in 2010. The highest number of studies was recorded in 2014 (n = 16), and citations peaked in 2016 (n = 518). Keyword analysis reveals that indoor soundscape remains an emerging topic, represented in only three papers (5.4%), mostly linked to terms such as “health” and “well-being” without a direct connection to “soundscape” as the central term. Further analysis identified 23 studies directly addressing indoor soundscapes, with open-plan offices being the most underrepresented setting, with only one study, followed by commercial spaces (e.g., retail shops, restaurants, cafes), with two studies.
