Whether you’re planning to create a relaxing spa, a recording studio, or just want to create a space for solitude, you’ll need an excellent soundproofing strategy. Building a soundproof room refers to the process of sound isolation where you block the noise coming from outdoors into the room. To build a 98% soundproof room means creating a space where you can block almost all traces of outside noise. But blocking 98% of incoming decibels is something that needs a bit of planning.
How to Make a Room Soundproof
To make a room truly soundproof, first and foremost, you need a decent budget and access to specialist materials, products, and applications. One way to attenuate the noise from exterior noise transmission is by creating a thick and heavy wall. This will ensure sound waves are weakened as they travel through the surface. But building walls like that is impractical and highly inefficient, so a more common approach is to construct two separate walls side-by-side (also known as a double wall) that will disconnect the exterior and the interior and ensure lesser sound transmission. This creates a void of dead air between internal and external walls and prevents vibrations from transferring between walls.
How to Soundproof a Room from Outside Noise
Creating a totally soundproof room cannot be achieved through decoupled walls alone. You need to combine it with suspended ceilings and floating floors. Building a metal or wood frame and then installing walls, ceilings and floor will help you achieve excellent soundproofing. Moreover, using soundproofing products such as mass loaded vinyl, fiberglass, etc reduce the amount of airborne sound transmitting through enclosures, firewalls, housings, cabs, heavy equipment, etc, and help in creating an efficient space.
Drywall is one of the best ways to help create a soundproof room. The best part about it is that drywall is cost-effective, easy to source and work with. And if you can source acoustic grade drywall, then you will get even better results. Drywall should be complemented with options like acoustic foam and sound dampening materials that will block and absorb sound waves.
