Parks in Philadelphia Are Installing High-Pitched Noise Machines to Keep Teenagers Away
MIAMI, FL - OCTOBER 11: Car window speakers are seen while "Back to the Future" is to be shown at The Blue Starlite Mini Urban Drive-In on October 11, 2013 in Miami, Florida. Many traditional drive-in theaters around the United States have closed but the owner of The Blue Starlite held a grand opening for his small outdoor facility, which can accommodate 20 to 24 cars and has seats near the front of the viewing area, with hopes it will become popular in the urban core of Miami.

The parks in Philadelphia are getting criticized for installing noise machines that make a high-pitched sound. Only people under 25 can really hear the noise . . . so they’re designed to keep teenagers out of the parks at night.
