We discussed in a previous page of how 2 different music lovers can still manage to remain in peaceful harmony with each other through the science of soundproofing. Which involves little more than investing time to understand the science of noise reduction which can properly soundproof a room. Once a solid understanding has been made you can than proceed in purchasing the right soundproofing materials that you will need for your project.
First rid yourself of the embedded information that surrounds soundproofing which is- insulation and soundboard. This is not to say that insulation does not help out in the sound/music reduction however it has it’s limitations as we shall see.
Soundproofing is not a one shot hit and run project. It takes understanding and a willingness to learn and try something new and different. Lets start with the four main principles in the science of noise reduction. 1) Mass 2) Absorbtion 3) Decoupling 4) damping.
The first basic knowledge to noise is to understand that sound travels as waves and vibration. Meaning the only way for a sound to pass through a wall is by vibrating that wall which in turn vibrates the air on the other side of the wall. Actually even sound traveling through the air like musical notes produced in Sweden are heard by your ear through vibration. The air molecules in the air vibrates from the sound waves which vibrates the drum inside your ear.
With this knowledge you can now understand our first principle which is that adding mass to a wall will add soundproofing benifits to your wall simply because it is heavier and harder to move meaning harder to vibrate. You also understand now why insulation does not help out this situation. Which brings us to the seacond principle in noise reduction “Damping” if we can somehow damp the wall which will reduce the vibrating consistincy of our wall and/or ceiling we can go very far indeed in reaching our goal. The next priciple of absorbtion applies to our good ole’ insulation which works by absorbing certain sound waves. This principle is applied often in music theaters and home theaters when we try to control musical waves from bouncing off walls.
