The basics of soundproofing – In order to understand the concept of soundproofing, you must first understand the concept of blocking sound. Specifically, there are only three ways in which sound can be blocked or noise can be reduced. These three ways are as follows: Space – The further away from a source of sound you are, the less likely it is that you will hear the sound.
Space impedes sound travel. Mass – This one is also simple. The more mass between the origin and destination of a sound wave, the less audible the sound wave will be once it reaches its destination point.
Dampening – This one is a bit more complex. Essentially, dampening is a way to absorb sound by forcing sound waves to travel through various layers of material with different densities, thereby obstructing the sound wave’s path of travel, and ultimately absorbing the sound wave before it has a chance to become airborne. Dampening works by limiting a sound wave’s ability to vibrate through different structures. This eventually results in the absorption of the sound wave.
Sound insulations are insulating materials that work to reduce the noise that enters a room from outside the home or from other rooms. These materials can be installed during construction, or later as an improvement project.
Basics of soundproofing:
- Absorption – absorbs sound waves that bounce in the space. Absorption can be achieved by installing absorbing materials into walls and ceilings.
- Damping – stops vibrational energy before it can build up and radiate as sound basically absorb and dissipate unwanted sound. Damping is the process of turning your barriers (drywall, sub floors) into dead panels that do not vibrate, thus preventing sound from passing through them. Damping is achieved by applying a damping compound in between two constrained layers.
- Decoupling – Decoupling is meant to separate the attachment of walls from the studs, thereby breaking the direct path of sound, which can be done using resilient channel, and more importantly – with resilient sound clips. This decoupling technique actually adds another component called “resilience” to the walls.
- Mass – Prevents the transmission of sound. Mass Soundproofing is sound dampening material that can be applied to walls, ceilings, and doors. Mass simply means creating a heavier wall by using more (another layer) and/or thicker material
