Acoustic underlay

Acoustic carpet underlay generally means that the acoustic carpet underlay has some sound reduction, or acoustic properties, the best acoustic carpet underlay will shut out most sounds, but this is also true of many of the top of the range rubber and foam carpet underlays, which are not given the name acoustic. Any carpet underlay will prevent some sound being transmitted. There are a variety of types of acoustic underlay. Different sellers will either have their own brand, or simliar products will be sold under different names. There are two types of sound reduction

Sound impact. This is where the carpet underlay stops the sound hitting the carpet being transmitted too far. For example, the sound of moving furniture. Some underlays only help with sound impact. This is common with, for example, felt underlays.

Sound absorbing, or airborne reduction. This is where the carpet underlay goes some way in absorbing some of the noise in the air. For example, the noise of someone snoring in one room won't be transferred to another. Airborne noise comes from common sound sources such as voices, TVs and radios. The higher the Db number next to the specification of the underlay, the better. For example, number of 46 shows that the underlay reduces the sound by 46dB. However, this is quite a simple way of looking at it, as the true measurements are made at specific frequencies. Best to check the technical stuff with your supplier.

The best acoustic carpet underlay is a combination of both of the above. A popular solution, though a considered purchase, is QuietFloor underlay, which is supplied as slabs that
