Noise pollution in Hong Kong is an insidious issue. In such a noisy city, many people have
become accustomed to the higher noise levels that underpin our daily activities. Noise is the
most common cause of complaints, but few consider noise to be a serious health hazard. However, noise has not only been linked to many serious health risks, such as hypertension and heart disease, but also to a deteriorating quality of life, by interfering with speech, performance, and ultimately, productivity. In a city as noisy as Hong Kong, those who have not been physiologically damaged by noise may nevertheless have been mentally affected by it.
