I created my studio in my little bedroom. I was impressed with the sound quality as I came out of my room. The first and probably the most important job that needed to be soundproofing the room. I understood that it is impossible to get a completely dead sound even in the most expensive recording studios, but I found a way to minimize much of the noise in my room and keep my condenser microphone from picking up so much of the room atmosphere.
*** Step # 1 is to decide which sound insulation method you want to use. You can either use egg cartons / cup holders for soundproofing or keep it simple and use two mattresses as soundproof vocal booth. You can even do both, it’s up to you. If you decide to use only the cup holder method, simply stack or drop the cup holders on the wall. Stapling becomes easier and the egg cartons / cup holders become stable. You will need enough egg cartons / cup holders to cover your entire room.

I tried to use cup holders first. I had to take them down because my mom was upset because I had them taped to the walls in my room. The cup holders covered all the walls and I had closed curtains over my windows. When I played my first recording after placing the cup holders on the wall, I noticed that my microphone still got a small part of the room’s atmosphere. I decided to try using my mattresses as a sound kiosk.
*** Step # 2 Take two mattresses and place them around your microphone along the corner of a wall in the room.

The mattresses absorb sound very well. They will also protect the microphone from a lot of noise coming from machines in the room such as the computer. When a vocalist performs the microphone in the mattress, the mattresses will absorb the sound of their voice and prevent it from returning to the microphone. When you record in the open (without any soundproofing), you may notice a cross-like effect of the vocals when you play them back. This effect is caused by sound bouncing off the walls and then entering the microphone. So you have the song that comes from the artist who travels into the microphone and an echo that comes from the walls that produces this effect. We want to prevent this from happening and we do it by using the mattress sponge. (Egg cartons and cup holders do not take as much sound as mattresses do, but if you do not have two mattresses, it may be your only option at that time.)
*** Step # 3 is Place the microphone between the mattresses and the wall. Use the chart to help you. (NOTE: The microphone should face the microphone against the walls. The singer should face the mattresses during recording to get the best possible results.)
Tips and warnings
This article will briefly explain how to soundproof a room for a studio. If you are trying to create a studio at home, this is probably the first task you need to do.
