Wincing at the annoyance of a dog bark,  or covering your ears as you pass a construction sight is the standard  way to guard against the harsh sounds. The pain threshold for humans is  120-130 Decibels. Any sound above 85 dB can cause hearing loss, and the  loss is related both to the power of the sound as well as the length of  exposure. Here are 10 sounds produced throughout history and how  incredibly loud they are. Just remember, human speech is only registered  at about 25-35 decibels. 10. Rock Concert/Speakers <a href="http://listverse.files.wordpress.com/2007/11/speakers.jpg" target="_blank"><img src="http://listverse.files.wordpress.com/2007/11/speakers-tm.jpg?w=280&h=280" alt="" class="fr-fic fr-dii fr-draggable " style="" /></a> A 400,000 Wat rock concert or a similar set of speakers mounted in a  vehicle can reach ear-splitting decibel levels. Is it any reason most  promoters recommend you wear ear protection to stave off the 135-145  decibel sound waves? 9. Fireworks <a href="http://listverse.files.wordpress.com/2007/11/fireworks.jpg" target="_blank"><img src="http://listverse.files.wordpress.com/2007/11/fireworks-tm.jpg?w=300&h=214" alt="" class="fr-fic fr-dii fr-draggable " style="" /></a> Though not typically heard up close, fireworks are still explosions  and are very loud. 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. 8. Gunfire <a href="http://listverse.files.wordpress.com/2007/11/gunfire.jpg" target="_blank"><img src="http://listverse.files.wordpress.com/2007/11/gunfire-tm.jpg?w=300&h=214" alt="" class="fr-fic fr-dii fr-draggable " style="" /></a> Gunfire for anyone unfortunate enough to be standing near it can be  quite damaging to the ears registering at a quite loud 145-155 decibels.  This is the very reason why you should always wear ear protection when  on a firing range. 7. NHRA Dragsters <a href="http://listverse.files.wordpress.com/2007/11/2006-dragster.jpg" target="_blank"><img src="http://listverse.files.wordpress.com/2007/11/2006-dragster-tm.jpg?w=300&h=169" alt="" class="fr-fic fr-dii fr-draggable " style="" /></a> 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. 6. Space Shuttle Launch <a href="http://listverse.files.wordpress.com/2007/11/shuttle-launch.jpg" target="_blank"><img src="http://listverse.files.wordpress.com/2007/11/shuttle-launch-tm.jpg?w=280&h=210" alt="" class="fr-fic fr-dii fr-draggable " style="" /></a> When the rockets fire, it is wise and, in fact, fully enforced, that  you stand at least a half-mile away lest you 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.                                                                                                                 5. The Blue Whale <a href="http://listverse.files.wordpress.com/2007/11/blue-whale.jpg" target="_blank"><img src="http://listverse.files.wordpress.com/2007/11/blue-whale-tm.jpg?w=252&h=300" alt="" class="fr-fic fr-dii fr-draggable " style="" /></a> 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. 4. Volcano – Krakatoa <a href="http://listverse.files.wordpress.com/2007/11/krakatoa.jpg" target="_blank"><img src="http://listverse.files.wordpress.com/2007/11/krakatoa-tm.jpg?w=300&h=189" alt="" class="fr-fic fr-dii fr-draggable " style="" /></a> The 1883 the Krakatoa eruption ejected more than 25 cubic kilometres  of rock, ash, and pumice and generated the loudest sound historically  reported at 180 Decibels: the cataclysmic explosion was distinctly heard  as far away as Perth in Australia approx. 1,930 miles (3,110 km), and  the island of Rodrigues near Mauritius approx. 3,000 miles (5,000 km). 3. 1-Ton TNT Bomb <a href="http://listverse.files.wordpress.com/2007/11/bomb.jpg" target="_blank"><img src="http://listverse.files.wordpress.com/2007/11/bomb-tm.jpg?w=300&h=238" alt="" class="fr-fic fr-dii fr-draggable " style="" /></a> 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. 2. 5.0 Richter Earth Quake <a href="http://listverse.files.wordpress.com/2007/11/earthquake-1.jpg" target="_blank"><img src="http://listverse.files.wordpress.com/2007/11/earthquake-1-tm.jpg?w=256&h=300" alt="" class="fr-fic fr-dii fr-draggable " style="" /></a> A sufficient enough quake to rend the ground in twain and destroy  buildings, whole rock, and human life reaches a decibel level of 235. If  you are caught in the epicenter and are unlucky enough to not be above  the ground in a plane or helicopter, the intense noise and vibrations  could kill you long before death by any falling object. 1. Tunguska Meteor <a href="http://listverse.files.wordpress.com/2007/11/060203tunguska2.jpg" target="_blank"><img src="http://listverse.files.wordpress.com/2007/11/060203tunguska2-tm.jpg?w=300&h=222" alt="" class="fr-fic fr-dii fr-draggable " style="" /></a> The Tunguska event was a massive explosion that occurred near the  Podkamennaya (Under Rock) Tunguska River in what is now Krasnoyarsk Krai  of Russia, at 7:40  AM on June 30, 1908. The explosion was most likely  caused by the air burst of a large meteoroid or comet fragment at an  altitude of 5 to 10 kilometers (3–6 mi) above Earth’s surface. It was  measured with the similar impact of a 1000-Mega-ton bomb with a decibel  rating 300-315. This is often considered to be the loudest single-event  in history. Bonus: Lake Taupo Eruption <a href="http://listverse.files.wordpress.com/2007/11/800px-lake-taupo-landsat.jpg" target="_blank"><img src="http://listverse.files.wordpress.com/2007/11/800px-lake-taupo-landsat-tm.jpg?w=300&h=222" alt="" class="fr-fic fr-dii fr-draggable " style="" /></a> Lake Taupo is a large lake in the middle of the North Island of New  Zealand.  The lake is the caldera that resulted from a massive volcanic  erruption in 180 AD.  It is New Zealand’s largest eruption in 20,000  years.  It ejected around 120 cubic kilometers of material, of which 30  cubic kilometers were ejected in the space of a few minutes. It is  believed that the eruption column was 50 kilometres high, twice as high  as the eruption column from Mount St. Helens in 1980. The resulting ash  turned the sky red over Rome and China.  This eruption was reportedly  heard in China. Lake Taupo today, is one of New Zealand’s popular  tourist attractions for its beauty and swimming. The fact that the lake  is the largest fresh water lake in Australasia, and approximately the  same size as Singapore, ensures it is a huge ‘must do’ component to many  tourists.</blockquote>
