I have some hearing loss now, but I totally ear-plug it up. Though being to the right of a loud drummer is hell. He has a snappy snare that really cuts through even my ear-plugs.
Agreed with Fishy, the chart shown isn't the best I've seen, but leaf blowers are a lot of white-noise, rock concerts are different sound so...
Rock concerts also sometimes stop being loud for a couple minutes while the Singer yammers.
