Quietness is defined both as the absence of noise (lacking high-intensity sound) and the presence of desirable, natural sounds.
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 QNS Index (Quietness + Naturalness): This index combines
Moving beyond just decibel reduction, modern quietness management includes perception-based soundscapes, urban planning (e.g., quiet areas), and ecological restoration. 2. The New Paradigm: Beyond Decibels
It acts as a public good, promoting mental and physical health by mitigating the adverse effects of noise, such as sleep disturbance, cardiovascular disease, and stress.
