We know we need to absorb block and damp the sound waves plus decouple the layers to stop sound transfer through the wall.
Insulation to block sound.
This is a tip i give to people trying to figure out what would help them blocking sound.
The ability of a material to block sound is measured by an sound transmission class stc rating whereas sound absorption is measured by a noise reduction coefficient nrc rating or a sound absorption average saa.
The quickest and cheapest solution is to add a single layer of regular 5 8 drywall over your existing walls.
Still at two inches thick the mineral fiber insulation has an nrc of 1 so it ll block 100 of airborne frequencies.
The room you wanna block is the swimming pool and sound is the water.
At some point the problem becomes impact sound which isn t really the insulation s domain.
Insulation foam should be fitted as neatly as possible without being overly packed it in as this will compress the air pockets inside it making your foam less effective at soundproofing.
In both cases the higher the rating the more effective the product.
To soundproof a partition wall consider the structure and weight of the material you want to use.
To control sound in a house we want to either absorb part or all of a sound wave or block it so noise transmission doesn t occur.
At four inches thick that number increases to 1 05.
The operative word for noise barriers is obviously heavy.
Luckily there are many ways to improve the stc ratings on your walls and help block more sound.
In some buildings they may add a layer of fiberglass batt insulation to help with noise and temperature control.
The properties of different insulation material allow it to absorb sound or reduce its transmission through that material.
Sound insulation foam is designed to be used inside floors ceilings walls and other internal spaces.
Factors to consider.

Reflective insulation such as radiant barrier works by reflecting radiant heat from the sun.
Your swimming pool is full of cracks and if you fill the cracks with foam it won t hold the water once you you start filling up the pool no matter how thik the foam is.
A fence intended to serve as a noise barrier or sound barrier will typically use thick tongue and groove boards in order to form an impervious barrier.
It is installed in the attic right under the roof and reflects energy from the sun which keeps your home a lot more comfortable but doesn t act as a sound barrier at all.
These boards are nailed to heavy rails which in turn are supported by heavy posts.
However not every type of insulation reduces noise.
