Build a Quieter Structure with these Sound Reduction Techniques

Noise can be a distraction in any type of building, and owners usually welcome any method that can cut it down. In homes it leads to a less peaceful environment, and affects the comfort level. In a business setting, too much noise can be disruptive to the daily routine. Metal transmits sound easily, but your steel building can be engineered for a quieter design.

How Sound is Transmitted

Sound moves in waves, traveling through air, solids and liquids. Solid materials like wood and metal will have different results in terms of sound transmission but the sound travels in the same ways. Noises can be airborne, that is, being transmitted through the air and then passing through the solid material where it is heard on the other side. Impact sounds are transmitted by some type of contact or movement. The sounds made by people walking around can travel around a metal building, but these sounds are also common in wood and concrete buildings as well.

Since sound radiates from the point of origin in waves, it not only travels through walls separating sections, but also through floors, ceilings and the small spaces where surfaces meet. The goal must be to keep the transmission of these sounds to a minimum.

Noise Reduction

The basic principle of noise reduction in buildings is by adding enough mass between walls and floors for proper sound insulation. Adequate mass in the area of the joists will also lead to a big reduction in noise transmission. Consider using two layers of plywood subfloor instead of one to cut back on sound. For the ceiling, two layers of gypsum board can have a positive effect on sound as well.

Heavy finish flooring can add the kind of mass that cuts back on noise. However, carpeting, which is lighter can also be beneficial in this regard. In steel buildings, floor interlayers, or floor mats can be the ideal solution for a quieter interior environment.

It is important to pay attention to the way sound travel through the spaces where the floor and the base of the wall meet. One solution is to use continuous subflooring across these areas. Minimizing vibration in the joists and subfloor will cut back on sound transmission considerably. Deeper joists generally provide better sound insulation, but joist thickness does not have much of an impact.
