A circular city approach, which includes the integration of electric vehicles and sustainable mobility, is essential to reducing noise at the source. quietness

Researchers are proposing the use of the CUQI , a new metric that measures urban soundscapes based on both acoustic intensity and context rather than just noise pollution, creating a better understanding of environmental quality.

This report draft examines as a crucial urban, environmental, and psychological resource, particularly in the context of increasing noise pollution in urban areas. Draft Report: The Role and Assessment of Quietness (2026) 1. Executive Summary Strategies include quiet delivery schemes

Noise from road traffic, rail, and aviation is a major pollutant. Strategies include quiet delivery schemes, urban planning buffers, and reduced noise transportation. 4. Key Recommendations
