Understanding Decibel Levels

For comparison purposes, a shotgun produces 155 dB on average. Prolonged exposure to high decibel levels can come from everyday sounds. When we're continually exposed to these noises, hearing loss gradually happens.

What decibel level is an M16?

These range in intensity from 157 dBP (peak unweighted decibels) for a 5.56mm M16 rifle to 183 dBP for a 105mm towed howitzer.

How loud is a fighter jet?

“The F/A-18 Super Hornet produces 118 decibels of noise, which is the equivalent of a rock concert,” Schrock said. “A reduction of four decibels would have a significant impact on noise issues related to our military aircraft.”

How loud is 1000 decibels?

On Earth, in our atmosphere at normal pressures, etc., 1000 dB is impossible. The most the pressure variation can possibly be is the standard air pressure at sea level, about 101.3 kPa, which equates to about 194 dB. You would nor perceive the loudness of such a sound as this intensity is enough to kill you instantly.

Why is 194 dB the loudest sound possible?

At 194 dB, the energy in the sound waves starts distorting and they create a complete vacuum between themselves. The sound is no longer moving through the air, but is in fact pushing the air along with it, forming a pressurized wall of moving air.
