Bang your head! Scientists at Stanford University created a sound that measures a whopping 270 decibels. The sound was created underwater and is believed to be the limit of how loud a sound can be.
Scientists used SLAC’s powerful X-ray laser to blast tiny jets of water with short pulses of high frequency energy. When the x-rays hit the microscopic stream of water, they instantly vaporized the water molecules around them. They also sent a shock wave traveling through the stream that can actually be seen moving to the left and right of the blast spot below:
The shock wave is the interesting part. Rather than an explosive division of liquid, a wave rolls outward. Scientists say the shock waves were just below the breaking point. That means it would also be the upper limit of how loud a sound can possibly get under water before it breaks it apart, essentially boiling it on contact.
Ready to put on a pair of earplugs and give the sound a listen? Not so fast. Scientists say earplugs would do no good. The sound is so loud, eardrums, heart, lungs, and other internal organs would instantly rupture.
