Speakers so powerful you can see the shockwaves

Recently, a video from an event held outside went viral. The speakers were so loud that people’s hair was literally blown back and shockwaves could be seen on camera. Which, while beautiful and interesting to look at, might not be great for your ears. Not to sound like a nerd, but if you’re next to a speaker that’s so loud it’s sending your chest cavity to another dimension, get some earplugs or move away. Tinnitus has no monetary value.

The speakers are so loud that they blur the lens of the camera and blow the hair back on the women in the video. Some concertgoers seem happy to stand right where the loud weapon is pointed right at their eardrums, but after a ew laughs, others can be seen bouncing and hitting the eject seat. Still, everyone has their own opinion, and the video is definitely cool. Sound has always been hard for me. So, I decided to talk about it in the “brief” piece for “Tuesday.” We usually think of things that make noise when we think about sound. Pure science says that sound is nothing but a vibration that moves through matter. A sound wave is the path that a vibration takes as it “travels through” something. 

Sound waves can move through the air, which is how we hear them. But it can move through both solid and liquid things. In this case, the grey and red bars in the animations above show how the fault is moving. When the earth shakes, it sends out a huge wave of sound.

What about the speed of sound waves? This is based on how fast a pressure wave can move through a certain medium. Since water is much harder to compress than something like air, there is less “give” to slow down the wave. Because of this, the wave moves more slowly. Just like when two people hold a stretched-out slinky between them, it takes time for a wave to travel down the slinky and reach the other person. When two people hold a broomstick, it is much less likely to bend. This means that when one person pushes, the other person feels it right away. Christopher Reiss is to thank for that link.

So, the speed of sound in air, 768 mph/1,234 kmph, is almost four times slower than the speed of sound in water, which is about four times slower than the speed of sound travelling through a solid like iron under normal conditions. coming back to us and letting us hear If you didn’t have ears, you wouldn’t be able to hear most sound waves, but you could feel the loudest noises on your skin. Ears are a result of evolution. They let us hear and understand sound waves in the air around us. Our hearing is so good that we can hear even the smallest sound waves in such detail that we can often figure out where the sound is coming from and what it means. It also lets us talk to each other. Our brains send information to other brains through complex patterns of air pressure waves. This is the most important way that people talk to each other.
