So... how loud is 89dB, anyway ? Is it some kind of level beyond which you have to wear ear protection, and thus everything which makes "less than 90" is rated 89 ?
I just tried to read up on Wikipedia about decibels, but it turns out that as well as logarithmic, they're complicated in all sorts of ways I don't understand. So I still have no idea how many decibels is "bloody loud".
