Blog / Sound blocking materials for floors – New dB4 Underlayment

February 11, 2021

Noise is any loud, unpleasant or undesired sound that compromises the privacy of a room. We all experience some sort of noise in our daily activities, whether it’s a loud garbage truck outside, an active neighbor on the floor above you, or even music or television in your own home. Noise is inevitable in the world we live in today; however, there are ways to reduce both airborne and impact noises around us with a variety sound blocking materials.

Noise barrier basics

Noise barriers are obstacles used to reduce the transmission of sound waves through a stiff barrier. From simple options such as a door, soundproof curtains, or portable dividers, to more intricate building materials such as noise reduction insulation, carpets, acoustic foam and mass loaded POE products for walls, ceilings, and floors.

As a best practice for sound control, individual barriers don’t manage and eliminate sound transmission. The entire assembly, design, and sound dampening components of a room will ultimately help in reducing noise.

NEW dB4 acoustic sound absorbing underlayment

In the design and building stages of residential or commercial buildings, it’s important to take sound reduction materials into consideration. They are a necessity to any home or office building to ensure a calm, quiet, and peaceful space.

Similar to the dB3 line of sound abatement materials for walls, dB4 is a safe and high performing underlay sound barrier that absorbs sounds and vibrations. dB4 is specifically designed to be used as a floor underlayment, and can be installed under most flooring types such as hardwoods, carpets and laminate finished flooring. Similar to the db3 application, install this subfloor product under carpet or hardwood flooring during the building process.
