As the world is getting noisier from living near the neighbours, top quality speakers, televisions, phones ringing, hence sound insulation has become more vital than ever.

Living in a house without proper isolation creates extra stress and may cause health problems from lack of quality sleep. Moreover, with the growing number of home businesses and staffs working from home, it is vital that a well isolated space is there. Here is an outline of the fundamental concepts of sound insulation.

Sound isolation involves six fundamental principles: conduction, resonance, absorption, mass, damping, and decoupling. Taking each of these principles into consideration will enhance the performance of the sound insulation project.

Conduction

This sound principle is often addressed as flanking. Vibrations from sound transmit through conducive materials to other conducive materials. This sound transmission is not direct, hence the loss from the transmission is hard to predict, but can be substantial. You can break the sound transmission through conduction by either damping or decoupling the materials. Bothe these ...

Resonance

Problems with resonance are most frequently created while trying to decouple or while using the same type of material in different layers. Resolving resonance problems while decoupling is easy. Just avoid creating more than a single air space in any assembly and insulate that single air space with the right amount of insulation. If you create extra air spaces by installing strong clips over the current drywall or building sound absorbing blankets in front of a current wall, then you can lessen resonance problems by insulating this newly designed air space. No matter whatever the situation may be, we suggest only a single air space per wall or ceiling gravity in any sound isolation assembly.

In respect to utilizing the same type of sound control products, this may be avoided by utilizing different densities of plywood or drywall in an assembly. Every building material will have a particular resonance point. This point will change depending on the type of product and the mass of that product. The resonance point is the weakest frequency point for that material in respect to the loss of sound transmission. Having two materials of the same type in the assembly will worsen the weak performance of that material at that frequency point. If you are adding more than a single layer of drywall or wood to a single side of the assembly then utilize various densities for every layer. Including a wetting compound such as Green Glue compound in the layering will lessen these resonance problems enough that multiple layers of the same material density are not an issue.

Absorption

Insulation is the chosen material for meeting the absorption necessities of a floor, ceiling or wall. Just the size of the sound control doors is vital and not the type of insulation.
