SOUNDPROOFING PROBLEMS

Soundproofing, also known as Sound Isolation, is a simple concept that requires a combination of solutions.  Sound travels from room to room by different methods; through the air and through the building structure itself.

Airborne sound can be controlled by a barrier that has mass.  A heavy, thick, massive boundary (drywall, concrete wall, ceiling, etc.) is required, and the more mass the better. The next question is what stops sound from vibrating through the building’s structure?  To start, all rigid connections in the building structure from one room to the next allow vibration to transfer, so by separating these rigid connections you can create Isolation.  Between the rooms all penetrations and openings need to be sealed airtight so airborne sound cannot pass through.

Modern construction practices give little thought to sound isolation, but Technature Inc.’s line of innovative solutions will bring you the isolation you need.

When sound is passing through a door, it can be happening in a couple of different ways.  Sound energy can transfer through the gaps around the door, underneath the door, through the door itself, or through a window in the door.  Most doors do not have adequate seals in place, and many have no seals at all.  This is why we offer a our NoiseGuard door seal kit which can be attached to almost any door. It will seal the gap around the door, helping to control the sound that would be coming through that gap.  We also offer an automatic door bottom seal which allows the door to swing freely when opening, but seals to the floor when closed.

For more professional applications we also offer a heavy duty acoustic door.  Our custom Media Doors minimizes the amount of sound transfer through the slab itself, as well as all the gaps surrounding it.

When both high levels of sound isolation and a visible line of sight are required between rooms the walls and windows should have equal STC (Sound Transmission Coefficient) levels.  Otherwise a weak point in the partition is created.  Ensure that your projects sound isolation goals are met by selecting the correct windows.

Technature Inc.’s line of acoustic windows are suitable for many applications such as recording studios, commercial windows, industrial, military, victim interrogation rooms and many more. With four models to choose from and the STC range of 45 – 56 , we can find the right window for your application.

There are two types of noise that transmit through a floor: impact and airborne. Impact noise is the result of people walking on the floor. Footfall causes vibrations in the floor. These vibrations spread through the floor, into joists, and then pass through the ceiling of the room below. It could also be from objects being moved or rolled across the floor, or vibrations such as those from a washer or dryer. Airborne noise is the sound that travels through the air, whether it’s people talking, a loud TV or thumping music.

All flooring projects begin with a sub-floor and can be complimented with other materials. Flooring underlayments are used to soundproof a floor. It’s important to choose the right type of underlayment for the flooring type.

Typically when dealing with interior walls, sound travels through drywall along common studs. The most effective form of isolation is done by “floating” a mounted wall over the studs using steel channels and RSIC clips. The channels are attached to the RSIC clips on one side, and the other side is screwed into the stud. RSIC clips have neoprene isolator pads on them that allow them to absorb vibration. These neoprene pads allow the drywall to float freely, breaking the rigid connection. The drywall is then attached directly to these steel channels.

By using this layering technique, sound isolation works by creating a space between the drywall and the studs. There are no common studs for sound to travel along, stopping the transfer of sound waves. You can increase the isolation of the wall by using multiple layers of drywall and by creating a larger air space.

Another reason why sound isolation is the most effective soundproofing method is that the air space between the wall or ceiling is increased. A vibration isolation material can be installed in this air space to trap the noise sound waves.

Also, sound isolation provides increased flexibility of the structure. Sound has a more difficult time traveling through flexible materials.

Typically when dealing with a sound source that is located outdoors the standard isolation products won’t hold up and often a slightly different approach needs to be taken to controlling the noise.  You need an isolation product with material that will be able to stand up to the rigors of changing weather, but can also be taken down and stored easily when not being used.

This is why Technature Inc. offers a special product for just this application, the EchoBarrier.  The idea behind this product was to create an easy to install and extremely durable noise barrier that can be rolled up like a sleeping bag when not being used.  Originally designed for use on construction sites, EchoBarriers use an optimal weight and density of PVC and are hand stitched to ensure they retain the maximum level of strength.  Part of their patent protected technology encompasses a unique waterproof lining on the back of the barriers.  The unique performance of the acoustic foam will therefore not deteriorate as the barriers age and wear.
