To put this 137.6 decibels of sound in perspective, the following are some incredibly loud sounds.
Rock Concert Speakers – A 400,000 Watt rock concert or a similar set of speakers mounted in a vehicle can reach ear-splitting decibel levels of 135-145 decibel sound waves.
NHRA Dragsters – Sitting next to a dragster as it fires up its engines and screams down the raceway can be more than just loud; it can be damaging to your entire body. At the 155-160 Decibel range not only will it severely to permanently damage your hearing, but it also vibrates your vision and makes it temporarily difficult to swallow. That’s why no one stands next to them.
One Ton TNT Bomb – Standing as close as 250 feet away from the impact, the resulting explosion from a 1 ton bomb creates a decibel count of 210. Without sufficient hearing protection, not to mention a complete sound-resistant bunker surrounding you, you could quite literally die from the intense vibrations that would literally shake you apart. Unless, of course, you were under the bomb.
Fireworks – Though not typically heard up close by most people, fireworks are still explosions and are very loud, even though they are not typically loud from far away. The sound heard from the sky is pretty loud, though not damaging, but at the bursting point the decibel levels reach a staggering 145-150. Even tests are performed under strict sound proofing to avoid any ear injury.
Call of the Blue Whale – While most people won’t hear this sound in real time, blue whales mostly emit very loud, highly structured, repetitive low-frequency rumbling sounds that can travel for many miles underwater. These songs may be used for communicating with other blue whales, especially in order to attract and find mates. The call of the blue whale reaches levels up to 188 decibels. This extraordinarily loud whistle can be heard for hundreds of miles underwater. The whale is the loudest, and, the largest animal on earth.
Gunfire – Gunfire for anyone unfortunate enough to be standing near it can be quite damaging to the ears registering at approximately 145-155 decibels. Wearing hearing protection on the firing range is highly advisable.
Space Shuttle Launch – When the rockets fire, it is not only wise, but in fact, it is fully enforced that you stand at least a half-mile away. If you don’t, you will get inundated by 165-170 decibels of painful sound. Unlike many other loud noises, the shuttle rocket sound is constant as it creates the thrust necessary to lift it from the ground.
