Noise and quiet

The noise issue:

Last month, I spent a cold morning wandering around Hampstead Heath, one of London’s largest green spaces, with a sound designer named Nicholas Allan. For many, the Heath is an escape. There are almost 800 acres of it: meadows and woodland, hollows and springs, hills and ponds.

I once lived in a bedsitter just off the Heath, so I spent a lot of time exploring it. There are several similarly vast parks in Seattle, which I spend a lot of time exploring.

In July, Allan awarded the Heath “Urban Quiet Park” status. He was acting on behalf of Quiet Parks International, or QPI, a non-profit based in Los Angeles that is “committed to saving quiet for the benefit of all life”. QPI’s purpose is to identify locations around the world that remain free from human-made noise for at least brief pockets of time. As humanity grows louder, these places are in danger of extinction, the organisation argues, even though they are integral to our wellbeing and to the health of the natural world.

At least one of the Seattle parks is one of those locations, I’m pretty sure. There’s a main trail that can be crowded on sunny weekend days, but there are also large meadows where you can stop and look around and see not a single human.

Allan spent four days in the park in total, monitoring decibel levels. To pass the QPI test, noise levels must remain below 40 decibels, similar to the hush of a library, for at least an hour.

The hush of a library? Is he kidding? There is no hush in a library; that whole idea has been banished. Maybe in the UK there still is but not in the brash loud US.

Though many of us drive, and fly, and listen to music, and turn the volume of our TVs up very high, and drill and saw and hammer, and live in busy cities, which are relentlessly loud, we do seem to broadly understand that too much noise is bad for us. To escape, some turn to wellness practices – meditation, sensory-deprivation tanks, silent retreats – which have turned quiet into a consumable product. 

Just go to a good park instead. If there’s not a festival or something going on (and if you’re not near any sports area), it should be quiet enough for a break from noise. Unless of course parks department people are mowing or blowing leaves or trimming hedges – I worked as a parks department people in the past and we made noise. Too much noise. The backpack blowers in particular seemed like an unnecessary intrusion to me.

Studies have shown that experiencing quiet can reduce stress and anxiety, bring down heart rate and blood pressure, improve mood, cognitive ability and concentration, and increase pro-social behaviours, such as generosity and trust. It is helpful to experience silence in long periods, though every little helps – a 2006 study found that even a minutes-long session can be beneficial.

There are also sounds that feel beneficial though. The sound of a brook or river, or waves on a beach, or wind in trees, or heavy rain – sounds that aren’t sharp, that are more or less regular, that are benign and natural.
