A Really Loud World

My god­daugh­ter Claire called last week to invite me to brunch. Yay! Who doesn’t love omelets and mimosas? Then she sug­gest­ed the orig­i­nal Carson’s on Main Street in Lexington. My response was an imme­di­ate and vehe­ment no. 

Can’t help but sound like a Gen Xer here, but that place is just too damn loud. The acoustics are so ter­ri­ble that you can clear­ly hear the bas­ket­ball game they have blar­ing in the bar but not hear a word your date says, even though they are sit­ting right beside you. Even when the food is good, I always leave there feel­ing a lit­tle nau­seous. Makes sense when you know that the mod­ern-day word noise aris­es from 13th-cen­tu­ry French root word mean­ing English nau­sea.

Our world is get­ting loud­er all the time. Every thir­ty years, noise pol­lu­tion triples, which is direct­ly cor­re­lat­ed to an increase in anx­i­ety, hear­ing loss, and ecosys­tem dis­rup­tion. Animals of all sorts—including humans—innately dis­like loud nois­es. In fact, humans are only born with two innate fears: a fear of heights and a fear of loud nois­es. We’re designed with an uncon­scious star­tle reflex that tight­ens our neck mus­cles to help pro­tect our brains when we hear a loud noise.

Sound is mea­sured in deci­bels (fun fact: deci­bels are named after Alexander Graham Bell, sci­en­tist and inven­tor of the tele­phone). Continued expo­sure to noise over 85 dB can cause hear­ing loss. Interstate traf­fic is about 80 dB, hair dry­ers and leaf blow­ers around 100 dB, loud con­certs 110 dB (this is why you will see me in my loop ear plugs at every show—see below for more info), and gun­shots and fire­works up to 140 dB.

What to do, oth­er than lim­it­ing your expo­sure to noise? 

Get into nature. Turns out, a sound doesn’t neg­a­tive­ly affect our hear­ing and ner­vous sys­tem in the same way a noise does. Now on a sci­en­tif­ic lev­el, sound and noise are tech­ni­cal­ly the same: vibra­tions in the air or water that we pick up with our ears. But many sci­en­tists are now dif­fer­en­ti­at­ing between the two, defin­ing noise as any­thing man-made, and sound as some­thing that occurs nat­u­ral­ly: think waves crash­ing on a beach, bird song, or wind whistling through prairie grass. Breathing is around 1dB, and rustling leaves around 20 dB. Even heavy rain­fall is only 50 dB.

Sounds (as opposed to noise) actu­al­ly improves our health in sev­er­al met­rics. Natural sounds soothe our ner­vous sys­tem. Planting more trees and shrubs in noisy areas helps to fil­ter and soft­en the deci­bel levels. 

Go some­where out­side and just lis­ten. Listen for the birds, the wind, the run­ning water. Listen for your heart­beat and notice how it grows slow­er and stead­ier, tun­ing into the nat­ur­al sounds you hear around you. 

Loop earplugs com­bine a patent­ed acoustic chan­nel and mesh to fil­ter sound waves, keep­ing qual­i­ty crys­tal clear. You hear the music per­fect­ly, but 20–25 deci­bels qui­eter. An absolute must for live music lovers like me.
