About/around summer 2019 but unverified until fall with 3rd party information. I KNEW that Nugent at Arrowhead concert would keep giving. Free ticket they said. Sure! I'll drive anon said. There's a reason anon says huh? since forever. Does tinnitus ever go away?
How Loud is Too Loud?
To put things in perspective, exposure to noises 85 dB and over for prolonged periods of time is harmful to your hearing, according to the National Institute for Occupational Safety and Health (NIOSH). Just an FYI, that’s about as loud as New York City traffic. The organization states that you can be exposed to sounds as loud as 85 dB for eight hours before suffering hearing damage, and that time is cut in half for every 3 dB added. That means you can only be exposed to sounds as loud as 88 dB for four hours, sounds as loud as 91 dB for two hours, and so on and so forth.
Ted Nugent Concert – 130 dB
A fun fact about Ted Nugent is that he spent some of his teenage years living in my home town. Another interesting tidbit is that he once played a concert so loud in Kansas City that farmers who lived 18 miles away complained. Moreover, Nugent's shows have been measured to be as loud as 130 dB. To quote the legendary musician, "When you come into a place, you might as well devastate it." Well said, Ted.
Kansas City Chiefs Game – 142.2 dB
If you thought Seahawks fans were the loudest, you haven’t been to Arrowhead Stadium. In 2014, the Chiefs faithful broke the record for loudest outdoor stadium by producing an impressive 142.2 dB of noise. To put this in perspective, that’s louder than a jet airplane flying 100 feet overhead. Chiefs fans, once again, have a lot to cheer for these days, so it wouldn’t be a surprise to see them break their own record in the near future.
