They arent - its just a cooincidence that they look like soundproofing materials called 'eggcrate'.
If I am trying to build a soundproof room, I would use foam and egg cartons for materials.
There is much controversy about whether using real egg cartons on the walls will soundproof a room. Garage bands with little money insist that this cheap form of soundproofing does Answers.com. There is soundproofing egg carton foam that is made and can be purchased in sheets to insulate walls--this method is definitely more effective than using the actual cardboard egg cartons. It is also more costly. If you need to soundproof a room for little to no money, you might as well try the egg carton method yourself--it can't be worse than bare walls. Once installed, see if the resulting soundproofing is myth or fact.

well this actually works to a point.get as many egg cartons as you can and line your walls with them with the points facing outward
You can buy egg whites at most grocery stores, usually in cartons or containers in the refrigerated section.

The gap under a door is one of the biggest sound leaks in any room, so a good door bottom is one of the cheapest upgrades you can make. It works best when you install it properly and pair it with a few other fixes. Choose the right type of door bottom Door sweeps (surface-mounted): a strip of rubber or silicone screwed to the bottom of the door. It’s cheap and easy to fit, and fine for light noise reduction. Check that it makes firm contact with the floor when the door closes. Automatic (drop-down) door bottoms: these are mortised into the door and drop a seal when you close it, then lift when you open it. They seal much better than a basic sweep and don’t drag on carpet or uneven floors, so they’re the better choice for offices, bedrooms, and studios. Threshold seals: a raised strip on the floor that the door presses against. These help on very uneven gaps, but they can be a trip hazard. Installation tips that matter Measure the actual gap before buying. Gaps vary, and a seal that’s too short leaves a leak. Close the door and check for daylight around the edges. If you can see light, sound is getting through as well. Make sure the seal compresses evenly across the full width of the door, with no rolled edges or lifted corners. Replace worn seals. Rubber stiffens and cracks over time and stops sealing. Don’t stop at the bottom A perfect door bottom still leaves the sides and top open, so add compression seals around the whole frame. A hollow-core door also lets plenty of sound through the door itself. Upgrading to a solid-core door gives a much bigger improvement than any seal alone. Realistic expectation A sweep or automatic bottom with perimeter seals can noticeably cut voices and TV noise. Loud or low-frequency noise (bass, music) needs a heavier solid-core or purpose-built acoustic door to make a real difference. Desound’s acoustic door range lists STC ratings and seal details if you want to compare a full acoustic door against upgrading what you already have.
