Sound can be categorized into two different types: Airborne sound & Impact Sound. Both act quite differently in respect of how they travel around.

Airborne sound is basically sound traveling around a room for airborne sound. It can be rebound off the floor or walls and cause vibration in these surfaces which can then be re-radiate these sound waves to other areas within the 'receiver space'. Impact sound on the other hand, is the noise caused when one object comes into contact with another. For instance the sound of footsteps on floorboards. The sound impacts created as a result can then pass between floors and walls from one room to another.

You can hear different sound around you. But, there are certain places like offices and homes, which tries to evade any form of unwanted noises. At these places unwanted sounds can disrupt concentration in the workplace and peace and quiet at home. At times, big rooms are subject to echoes because the walls are unable to absorb sound, therefore bouncing it back across the space in the room. Soundproofing is one of the effective ways to lower the amount of sound. However, before you soundproof a building there are few things that you need to be aware of, such as the quality and methods of construction of the building.

Here are the two basic ways to reduce and control noise:

Increasing Mass – It is important to note that the more density a floor or wall has the less sound will make it. So, to reduce the sound try doubling the mass. It will give a 5 decibel reduction in the sound transmitted.

Additional Layers – Another effective way to reduce sound is to add several layers to the construction of a wall or floor. Make sure that every layer is made of soundproofing materials to reduce airborne and impact noise transfer.
