What I Learned Today

A sound wave at 165 Decibels (dB) causes frictional heating (due to the extreme compression and expansion of air) sufficient to catch a person’s hair on fire.

A sound at 160 dB will instantly perforate a person’s eardrum.

In comparison, the level where sound becomes painful to humans lies somewhere in the neighborhood of 120 dB to 130 dB.

    Ah yes. The 120 to 130 dB is known to us science types as the “threshold of pain”. I always wanted to start a band called that with the motto “120 dB all the time!”.
