Sound Isolation Systems

Our Products

The isoTRAX® soundproofing system is one of the easiest ways to incorporate highly effective sound deadening materials inside a wall or ceiling. The basic wall system consists of a set of rails and sound deadening pads that offers coverage for up to 64 square feet. Ceiling packages are also available, and multiple units can be paired together to offer a complete acoustic isolation solution for a larger room.

What Is Sound Isolation?

Sound isolation systems block noise by creating separation between two surfaces that the sound attempts to pass through.

Sound waves that hit a surface cause vibrations. When the surface is one solid surface, the vibration affects the entire fixture, and the sound works its way through. Creating a second surface with an air gap between them prevents the sound from transmitting through the entire structure.

Contractors use the isolation process, also known as decoupling, to prevent noise transfer between rooms. It’s possible to decouple walls, floors and ceilings. Decoupling can either occur during a room’s construction or afterward by building a new fixture with a space between it and the original. Builders enhance the decoupling effect by padding the studs or joists with porous materials. Adding sound insulation or a sound barrier will also increase the effects.

Is Sound Isolating the Same as Noise Canceling?

Sound isolation and noise canceling are separate concepts. Sound isolation systems prevent noise from reaching a new area. In the case of room soundproofing, isolation stops noise from leaving one room and entering another. Sound-isolating headphones also prevent outside interference by sealing the listener’s ears from outside noise. Noise cancellation uses offsetting frequencies to drown out noise. Noise-canceling headphones produce ambient sound that cancels out incoming noise.
