You could thicken the walls and attach on the walls and ceiling a sponge-like thing that absorbs sound and reflects it, which has bumps a bit like vili (ask what are vili in search box above if not sure).
Usually very dense. sound cancelling material in the walls or coating the inside of the wall of the "soundproof" room. Also see Acoustic Foam.
There are very few ways to completely soundproof a room. One is to put sound-dampeneing materials on all surfaces, and to make those surfaces in certain shapes that absorb and minimise the reflection of sound; the design, shape and size of the room of the room itself also matters. It can cost a lot - multpile thousands - depending on the quality of the dampening and whether any changes are needed to the structure.
those that are photo sentitive
yes. there could be other openings in a room
I could feel the tension in the room.
bECAUSE IT IS SAD
There are many places where one can buy materials in an attempt to soundproof a room. These places include, but are not limited to, Lowe's, Ebay, and Amazon.
If I am trying to build a soundproof room, I would use foam and egg cartons for materials.
There are many possibilites on getting advice on how to soundprood a room. One could ask in a home improvement store or, alternatively, one could search on websites like wisegeek or community.homedepot.
Maybe just the celing and floor?
It stays in the room and does not leak out into the surrounding areas. If you wanted to diffuse that sound you would use acoustical panels or acoustical baffles in order to absorb the sound from bouncing around the room. A soundproof room means it contains the sound in the room. Acoustical treatment is meant to diffuse and absorb the sound which is in the room.
Of course soundproof foam will reduce the noise escaping from the room. If you cover the walls and ceiling there will be very little noise escape through the floor.
You can buy soundproofing foam online, or use carpeting or foam mattress material.
I am about to reveal one of my most innermost secrets to you. You will find that the innermost room is soundproof.
It depends on what material you want to use. $1 to $5 per square foot of wall space and $300 to $950 each soundproof windows. This link should help you. See related links
Studio foam and fiberglass panels are meant to minimize the reflected sound in the room to improve the quality of the mix or performance. It is not designed to soundproof the room. The only way to truly soundproof a room is by using special building materials during construction, such as acoustic sheetrock, and isolating the vibration of the walls from external contact. Usually this involves creating a room within the room with an air barrier and isolating joist supports.
