Ambient noise criteria framework for future environmental noise mitigation targets in Singapore

This study aims to establish a framework for outlining future noise mitigation strategies tailored to the unique context of Singapore and evaluates potential precautions. Singapore, as a city-state, is known as a 'city in a garden,' situated in the typically tropical climate. By incorporating a comparative analysis of noise criteria from local guidelines across countries from Europe, America, and Asia, the study aims to place Singapore's acoustic limits within an international context. This comparison, enhanced with the World Health Organization's health and well-being standards, seeks to establish a comprehensive framework for acoustical design assessment in residential, office, and educational buildings targeting resting and cognitive functions. In conclusion, starting from a global perspective, the study points to the importance of focusing on the local context and acknowledging the challenges and benefits that the context brings for acoustical comfort. The study discusses the importance of context and content in crafting acoustical design criteria, considering the impact of biophilic design and active noise cancellation windows to achieve adaptive acoustic comfort in Singapore's built environment.
