Making cities feel quieter

Urban noise pollution poses a significant global health risk, with the World Health Organization predicting that 2.5 billion people will face hearing loss by 2050. In cities like Mumbai, noise levels frequently reach 80 decibels—well above recommended limits—causing residents to struggle with stress and sensory overload. To combat this, urban planners and artists are utilizing "soundscaping," a method of introducing calming sounds into public spaces to mask chaotic city noise. A notable example is an immersive installation in a Montreal park that uses recordings of "squeaky" sand and ocean waves to create a more relaxing environment. This counterintuitive approach demonstrates that adding specific, pleasant sounds can actually make a busy area feel quieter. While a whisper measures only 30 decibels, the roar of modern city life requires these innovative acoustic interventions to protect mental and physical well-being.
