The examples can be multiplied endlessly. I would suggest that all these abuses exist only because we have not yet developed the awareness that we are responsible for the noise we produce. It's widely accepted that we have responsibility for our garbage. Drop a candy wrapper on the ground and you are potentially liable to a stiff fine. But haul out your gas-powered leafblower to clean a little dust off the driveway, while spreading acoustic garbage over a square mile or more, and you are applauded for keeping your home tidy and presentable.
Noise is garbage, and it is a particularly insidious form of garbage.
It destroys community life, pursues us into our homes, keeps us from sleeping, and is a cause of many stress-related illnesses as well as hearing loss. The current destruction of silence in our world is an environmental catastrophe. Yet even the environmental movement seems oblivious to it, as evidenced by the huge speakers erected at Earth Day celebrations across Canada, putting out music and speeches at literally deafening volumes. Everyone has the right to use it, but no one has the right to abuse it. Let's start using it responsibly.
