I now interrupt a somewhat slow news day in Kentucky to ask a very important question: can you hear the sound in this audio clip? If not, you are officially old.
On Friday, NPR’s Morning Edition did a story about the “Mosquito,” a sonic device that emits extremely loud, high-frequency noises to keep humans and animals away from designated areas. The sound is in the 17.5 to 18.5 kilohertz range, and therefore inaudible to most people over the age of 30 because of hearing loss due to aging or noise pollution. The city of Philadelphia is using Mosquitoes around its parks, recreation centers, and playground areas at night in hopes of reducing vandalism; as you might expect, that’s rubbed some people the wrong way — which is a totally valid debate — but as someone who can’t hear the noise, I just want someone to describe it to me.
Listen below around the 33-second mark:
What do you hear? Is it our old pal Slim Whitman??
