@inventionontt: Original Video Credit: IG/carline_detailing_ An ordinary metal bucket makes it easy to hear how much difference sound-deadening materials can make. Untreated metal produces a sharp, hollow ringing sound when tapped, but after applying vibration-damping sheets and adding acoustic foam, the sound becomes noticeably duller and quieter. The comparison reveals just how much noise comes from the metal vibrating. The two materials work in different ways. Vibration-damping sheets reduce the metal's tendency to ring by converting some of its vibrational energy into heat. Acoustic foam absorbs part of the sound bouncing around inside the bucket, reducing reflections. Together, they help control both the vibrations of the metal and the noise traveling through the enclosed space. Similar materials are commonly installed inside vehicle doors, floors, and body panels to reduce rattles and unwanted noise. Thin metal panels can vibrate in response to road impacts, engine movement, and powerful speakers, sometimes interfering with audio clarity. Controlling those vibrations can make a vehicle quieter and help its sound system perform better without replacing the speakers. #shorts #Science #education #learn #invention

ZzzGeek :

How much $ to cover my room in ts

Zcheldarin :

If I lined the inside of my car with this material, would it make the noise isolate?

Derektok :

Deer blind material.

BrekkenA :

Wonder what the weight of the bucket is before and after

FNGARY :

Thank god I can make all my buckets quiet

masentakeya2 :

My helmet for the apocalypse when dooing some medevel stuff

Hubcaps :

not that it doesnt actually reduce noise sound deadining is amazing but when you put the bucket over the phone you held down the padded version, you should hold both down in fairness even if the outcome is the same

Jonathan Lynn 👑🐓🍭 :

now nobody will hear me shitting in the woods.

Crisco :

How can I do this with my car?

Ari Sisk :

My company invented a paint version of this 30 years ago. Foam and padding can get wet and deteriorate. Water based paint doesn’t ✨

kingoscar :

not how that works

L. :

this is the type of stuff that that well needed to be lined with when the crew in the lord of the rings were in Mines of Moria

Grizzly450 :

Why didn’t you hold the first bucket down like the second one while over the phone.

Goat_milk06 :

Can I just wear it as a hat?

flywheel634 :

nope

M0x-Pox618 :

Would dropping it make noise?

GabaGhoulGirl420 :

I wish I could have these in my apartment because of the neighbors

J :

a bucket

pipedpiperfj5.0 :

adds weight to the car

bassboostedE9x :

Someone link me the green stuff he used

nisemoto :

Not exactly an invention. That sound deadening method was available for cars for a while now

LogainDiablo :

nah

M_Top :

wth, it doesn't even sound like metal anymore

Vane :

Mpg even lower

Burzummmm :
