Sound complexity as a strategy for livable and sustainable cities: The case of an urban waterfront
Abstract Public spaces underwent a notable shift in their acoustic profile during the societal restrictions resulting from the COVID-19 pandemic. A silver lining emerged from this global crisis, with noticeable improvements in public acoustic environments due to reduced noise levels resulting from restricted mobility. This research focuses on the acoustic environment of Thessaloniki’s waterfront, a Mediterranean metropolis in Northern Greece. Waterfronts of Mediterranean coastal cities provide unique acoustic environments worthy of protection from environmental noise. By analyzing sound level measurements and recordings during the 2021 lockdown and comparing them to the post-lockdown period in 2022, we aimed to explore environmental noise and acoustic complexity indicators. The study’s findings revealed a significant increase in acoustic complexity during the lockdown, underscoring an inverse relationship between noise levels and acoustic complexity. Urban waterfronts, like Thessaloniki’s, hold great potential for enhancing acoustic complexity and subsequently improving the acoustic quality of public spaces while protecting them from environmental noise. This research sheds light on the possible use of sound complexity as an environmental quality standard that can be incorporated in sustainable urban planning and design.
期刊介绍:
Ever since its inception, Noise Mapping has been offering fast and comprehensive peer-review, while featuring prominent researchers among its Advisory Board. As a result, the journal is set to acquire a growing reputation as the main publication in the field of noise mapping, thus leading to a significant Impact Factor. The journal aims to promote and disseminate knowledge on noise mapping through the publication of high quality peer-reviewed papers focusing on the following aspects: noise mapping and noise action plans: case studies; models and algorithms for source characterization and outdoor sound propagation: proposals, applications, comparisons, round robin tests; local, national and international policies and good practices for noise mapping, planning, management and control; evaluation of noise mitigation actions; evaluation of environmental noise exposure; actions and communications to increase public awareness of environmental noise issues; outdoor soundscape studies and mapping; classification, evaluation and preservation of quiet areas.
