"How loud is 138 dB? Very, Very, VERY LOUD!
138 dB C-weighted is approximately equal to 30,000 Watts of sound
power.

The Chrysler Air Raid Siren is the loudest sound signaling device ever
built. The threshold of pain is 130 dB, anything above that level
causes immediate ear damage. The Chrysler Air Raid Siren produces that
level of sound nearly 200 feet in front of the projectors. "

One might question the wisdom of a protective device whose design
basically assures permanent injury to those it would try to
protect ....
