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
Traditionally, quiet areas were identified solely by noise levels (e.g., Ldencap L sub d e n end-sub 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.
