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 air,  or 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 ossicles,  which amplify the sound. The sound waves then  

enter your inner ear and travel to the cochlea,  which 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 enough,  or 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 like a  leaf blower for over an hour. But anything  

above 100 dB can cause hearing loss since,  due 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 minutes,  and someone shouting directly in your ear, 110 dB,  

would cause hearing loss in less than 2 minutes.  Standing 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 gruesome:  according 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
