  • This one question that was sent to me  a month ago has been stuck on my mind  

  • ever since. It's something I really never  thought of until this person asked, "Hey,  

  • Bloc, how much loud can kill you?" I'm  putting grammatical errors aside here,  

  • people. I get what they're trying  to ask. We're going to explore this  

  • question soundly for this episode. Eardrum  roll, please. Thank you, Triangle Bob.

  • Hey there, welcome to Life Noggin! The world  is full of sound, like "Grey's Anatomy";  

  • it's always happening. But could a sound be  so loud that it actually sends you to the  

  • great beyond? First things first, let's break  down how we hear things. Sounds are made when  

  • objects vibrate and they travel through the airor any medium, as a wave. The visible portion of  

  • your outer ear, called the pinna, collects these  sound waves and sends them down the ear canal,  

  • where they come into contact with the eardrum. The  waves vibrate the eardrum, moving the teeny tiny  

  • bones in your middle ear, known as the ossicleswhich amplify the sound. The sound waves then  

  • enter your inner ear and travel to the cochleawhich contains a fluid that moves in response  

  • to the vibrations, and 25,000 nerve endings that  translate the vibrations into electrical impulses.  

  • These impulses then travel along the auditory  nerve to the brain. Isn't that fascinating?

  • This is how you hear everything from  the soft rustling of leaves in the wind,  

  • the incredible musical stylings of Chapel Rone, to  the roar of a very loud jet engine. Though these  

  • sounds certainly have different effects on your  hearing, loud sounds can damage certain components  

  • in your ear, especially the hair cells in the  cochlea. These cells ride the waves created by  

  • the vibrations and bend when they come into  contact with the top of the structure. This  

  • is what creates the electrical signals that are  sent to your brain. But louder sounds cause more  

  • movement and bending, which can damage and even  kill the cells, resulting in hearing loss. This  

  • can happen quickly if the sound is loud enoughor over time with repeated or prolonged exposure.

  • Sounds are rated by their intensity, which is  measured in decibels on a logarithmic scale.  

  • That means that the intensity grows really fast  as you go up the scale. Things like breathing,  

  • 10 dB, and talking, 60 dB, don't harm  you at all. Damage isn't caused until  

  • you're listening to an 80 dB sound likeleaf blower for over an hour. But anything  

  • above 100 dB can cause hearing loss sincedue to the logarithmic scale, 100 decibels is  

  • 1 billion times more powerful compared to 10  dB. So, a car horn blaring 5 m away, 100 dB,  

  • could result in hearing loss after 15 minutesand someone shouting directly in your ear, 110 dB,  

  • would cause hearing loss in less than 2 minutesStanding next to sirens, 120 dB, a jet engine,  

  • 140 dB, or firecrackers, 150 dB, would immediately  cause hearing loss, not to mention pain.

  • But here's where it gets pretty gruesomeaccording to researchers, at about 175 dB,  

  • your eardrums would burst, and anything over  210 decibels would cause your lungs to rupture,  

  • and you to, um, well, die. But to reach that  level, you need to be next to an insanely  

  • loud sound, and even the world's loudest  rocket engine only reaches 204 dB. But  

  • even sounds that you can't hear can affect  you, depending on the intensity, frequency,  

  • and exposure time. Infrasound has been found  to affect the central nervous, cardiovascular,  

  • and respiratory systems, resulting in things  like loss of concentration and alertness,  

  • depression, and vibration of internal  organs. Woo, um, well, that is alarming.

  • I think I'll go search for a soundless place  now, someplace quiet to meditate. Actually,  

  • that would mean I'm alone with my own  thoughts, so never mind. Actually,  

  • let's try something more fun. Let's hear  some nice sounds! Name an album or song  

  • you can't stop listening to. I want some good  music recommendations, people. Let me know in  

  • the comments. Do all the things that help this  channel grow. We really appreciate it. Click
