A normal person’s threshold of noise is around 125 dB. A full blast rock metal concert can go up to 130 dB, which is the same level as if you were standing right beside a full-running jet engine. At 135 dB, one can actually feel a slight cooling sensation in the air. At 140 dB, the throat and the vocal chords start to vibrate involuntarily. At 142 dB, even the chest starts to pound. Once it reaches 148 dB, the sound level becomes extremely uncomfortable and even painful. At 150 dB, one can feel a sensation similar to drowning. If it gets to 155 dB, even the body’s core starts to shake. Three notches later at 158, you can feel intense nausea because of the violent vibration. Eardrums will probably rupture at 190 dB. At 198 dB, the sound gets so intense that it can actually cause death.
