If you’ve ever lived around an airport you know how impossibly loud it can get. I live in the flight path of the Burbank/Hollywood Airport on days the winds blow north/south, even with some pretty good insulation it can still be distracting. Imagine what’s it’s like to live near the 3rd busiest airport in the world. Amsterdam’s Schiphol Airport deals with 1,300 flights per day (that’s nearly a flight every minute) and it’s near one of the heaviest populated areas in Europe. Since it’s an extremely flat part of the word, an aircraft’s ground-level noise propagates across the flat ground and can be heard up to 28 miles away, and that causes a lot of upset residents and lots of complaints.
But the airport has done something about the noise by hiring an architecture firm called H+N+S Landscape Architects and artist Paul De Kort to implement an unlikely solution that presented itself after the land nearby was plowed and the noise unexpectedly dropped.
De Kort dug a series of hedges and ditches just past the edge of the runway with the distance between the ridges spaced at about the wavelength of the aircraft noise output, which is about 36 feet. Then they placed 150 straight, symmetrical furrows with six foot high ridges between them. These form to what amounts to a low frequency baffle that has reduced noise levels by more than half.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
