“ How loud is 240 dB? Like the Richter scale, the decibel scale is not linear but logarithmic. So 10 dB is 10 times louder than silence. 20 dBis 100 times more powerful. 30 dB is 1000 times more powerful, and so on. Exposure to 110 dBA will most likely damage human hearing after two minutes. The sound of a jet taking off is about 140 dBA. “
