Environmental Noise -- How it Hurts Us, and How We Can Silence It
Although its presence lingered unaddressed for many years, environmental noise is now recognized as a significant health issue. Environmental or ambient noise is unwanted or harmful outdoor sound created by human activities, including noise emitted by means of transport - road traffic, rail traffic, air traffic - and from sites of industrial activity. From delivery trucks to air conditioners, we are constantly bombarded by sounds that go unnoticed for the most part. However, out-of-earshot should not mean out-of-mind. It is precisely these innocuous environmental noises that should be sounding an alarm.
