The Silent Epidemic: How Noise Pollution is Undermining Our Health

An exploration into the dire health impacts of noise pollution, uncovering personal stories and expert insights into this often overlooked crisis.


Noise pollution, an invisible yet pervasive threat, is linked to serious health issues including heart disease, diabetes, and even dementia. Experts and affected individuals shed light on the urgent need for awareness and action against this silent epidemic.



We live in a cacophony of sound, often unaware of the detrimental effects this invisible force is having on our health. Noise pollution may be a common nuisance, but its toll is significant, contributing to heart attacks, type 2 diabetes, and more disturbing links to dementia. Prof. Charlotte Clark from St George's, University of London, highlights the growing public health crisis from our noisy environments, which many fail to recognize.

I joined Prof. Clark in a sound lab for an experiment measuring my body's response to various noises, donning a monitor that detects changes in heart rate and sweat production. With headphones, I experienced multiple sounds, discovering the overwhelming stress evoked by traffic noise from Dhaka, identified as the world’s noisiest city. As my heart raced, it became clear that such persistent noise could strain heart health, leading to chronic ailments over time.

Prof. Clark explained that sound impacts our emotional state, activating the amygdala, which initiates our fight-or-flight responses. The result? Increased stress hormones and cardiovascular risks. Alarmingly, this exposure remains constant—even during sleep—damaging our bodies in ways we might not realize.

I met Coco in her bustling Barcelona neighborhood, immersed in the perpetual noise of street parties and late-night gatherings. Despite the idyllic surroundings, the constant clamor has left her feeling overwhelmed, contributing to serious health issues, including hospital visits for chest pain. Research shows traffic noise alone causes around 300 heart attacks annually in Barcelona, illustrating the pervasive danger across urban settings.

Dr. Maria Foraster emphasized the necessary quiet levels for health—53 decibels during the day, and even lower at night. She equates noise pollution's impact on health to air pollution, yet the public grasps the latter more readily, making it crucial to raise awareness about sound's detrimental effects.

Across locations like Dhaka, urbanization fuels this crisis, with incessant honking contributing to the chaos. Activists, such as artist Momina Raman Royal, are drawing attention to the health hazards posed by noise, urging for a cultural shift in how we relate to sound.

Dr. Natalie Mueller pointed out an innovative approach in Barcelona: the creation of "superblocks," which convert busy streets into pedestrian-friendly areas. This strategy aims to reduce noise and its associated health risks. However, only six out of a planned 500 have been established, indicating the challenge of implementing long-term noise reduction solutions.

The global burden of noise pollution echoes a pressing concern. Syeda Rizwana Hasan, Bangladesh's environmental minister, expressed a commitment to reducing urban noise through policy changes and public awareness campaigns. Although change won't be swift, incremental steps can forge a path toward a quieter, healthier future.

As we navigate through our daily lives, it's essential to seek moments of reprieve from the noise that surrounds us. Dr. Masrur Abdul Quader aptly describes noise as "a silent killer and a slow poison," illuminating the need for us all to acknowledge and combat this silent epidemic.
