I bought two and I hooked them up and they sounded like a whistle

I bought some too and it definitely isn't 300db and doesn't sound like a train. However it is a little louder than stock horn

A nuclear bomb explosion is approximately 240dB+. So how can this be legally sold if it's going to kill everything within ½ mile with it's 300dB?

Well technically it's not the sound of the nuclear bomb that kills everyone, but this horn is nowhere 300db. It is however louder than my factory horn. I have since upgraded to GAMPRO air horns. If you want a true sounding good quality train horn I recommend GAMPRO

Why don't I hear everyone that bought this horn no matter where I m on earth? Krakatoa was 300db and loud enough to go around the planet 3 times.

Because they aren't 300db unless you buy the booster. I tried these and they are not any louder than my stock horn. Save your money!

If I buy this 300dB horn, will I get in trouble for causing property damage since it's blast would flatten entire cities?

If it happens in Chicago then your doing it a great public service. Go forth and blast those babies like you were at Jerico!
