dB is the abbreviation for decibel which is a logarithmic scale.
Every 10 dB is 10 times louder than the next. e.g. 20 dBA is 10 times louder than 10 dBA. 30 dBA is 100 times louder than 10 dBA, etc
Every 10 dB above 100 dBA would be 10 times louder, so 350 dBA would be 10,000,000,000,000,000,000,000 louder than 100 dBA.
I think they might be BSing just a bit.
