Abstract
Achieving optimal acoustic conditions in urban public areas emerges as a crucial element in enhancing the overall well-being and satisfaction of inhabitants. Urban parks stand out as pivotal public spaces, with park benches playing a fundamental role as key pieces of furniture contributing to visitors' comfort. The primary aim of this study revolves around evaluating the suitability of existing acoustic comfort standards concerning the placement of seating facilities within parks. Employing a descriptive-analytical approach, the research focuses on Laleh Park in Tehran as a case study, where the sound levels at designated seating areas are quantified using a decibel meter, while subjective perceptions of acoustic comfort are gathered through a structured questionnaire. Through a spatial analysis integrating both objective and subjective data, areas with inadequate acoustic conditions are pinpointed. Notably, the calculated Pearson's correlation coefficient (0.692) highlights a significant association between objective and subjective assessments of acoustic comfort at seating locations within the park. Results reveal that southern seating areas, encompassing approximately 15 stations, exhibit substandard acoustic comfort mainly due to their proximity to the bustling Keshavarz Boulevard. Conversely, seating locations near Bazarche Laleh Park and the Tehran Museum of Arts are deemed satisfactory. Out of the 19 monitored stations, 14 feature bench seats, 4 offer backless seating, and 1 provides pavilions. Among the stations with moderate acoustic comfort, comprising 38 stations in total, bench seats are predominant (23 stations), followed by backless seats (10 stations) and pavilions (15 stations). Conversely, stations with superior acoustic comfort are predominantly situated in the northern section, adjacent to facilities catering to children and teenagers as well as the carpet museum. In conclusion, the acoustic comfort level at Laleh Park is moderate to subpar concerning its geographical setting. The study suggests considering the installation of acoustic-enhanced park chairs as a potential solution to improve overall maintenance, in conjunction with other pertinent factors.
