Why Quiet Mark?
"I couldn't hear my baby crying over the noise of the hairdryer"
The damaging effect of excessive noise on health, productivity and social cohesion is seriously underestimated. World Health Organisation research shows that environmental noise pollution affects mental and physical health and is now second only to air pollution as the world’s largest killer pollutant. Across an estimated population of 340 million people, at least 1 million years of healthy living are lost each year due to noise pollution in Western Europe.

In our fast-paced lives, vibrancy is exciting and necessary. But this heightened state can only be valued if there is also the opportunity to choose the alternatives of calm, quiet and the chance to switch off. Quiet Mark was established to provide a credible, independent public health product symbol and directory to help consumers and industry easily identify quietest products for the home, at work and for public spaces.
