Many of us don’t even notice how much noise pollution is in our daily life. We habituate to the constant flow of noise and we aren’t aware of how much damage noise pollution is causing to ourselves and the natural world around us.
And according to the World Health Organization, the threshold for humans is about 35 decibels. “So when you are experiencing more than 35 decibels, you’re actually creating a stress level on yourself and you’re building up stress hormones,” says Gordon Hempton, founding partner of Quiet Parks International, a non-profit committed to the preservation of quiet for the benefit of all life.
