Carpet Noise Reduction Coefficient

Flooring are the product s sound absorption and noise reduction capabilities.

Carpet noise reduction coefficient.

Carpet having an. Nrc stands for noise reduction coefficient and is the standard rating for how well a material absorbs sound. At patcraft we understand how sound affects environments and have conducted industry leading acoustical testing on our carpet and resilient products which can help you select the correct flooring. Even so no flooring material can provide all of the necessary acoustical management within a space.

Carpet vinyl cork rubber and other types of resilient flooring have higher nrc ratings than hard unforgiving surfaces such as tile stone hardwood and bamboo flooring. Nrc ratings of common room finishes are provided in table 1. If the carpet is installed with an underlay its nrc rating will almost double. Here s some hard data.

Typically the nrc rating of a material is viewed as a percentage. This is more conceptual than physically achievable. Independent laboratory tests show that carpet and textile composite flooring control noise more effectively than any other floor covering. Carpet has a noise reduction coefficient of 40 to 50 much higher than hardwood s 40 to 50.

Different materials have different nrc ratings that range from 0 00 1 00. So a carpet on rubber underlay could easily have an. Carpet is a softer surface which means it absorbs noise while hardwood reflects it that noise of course being footsteps. The sound isolation company offers 3 carpet underlay options designed to reduce sound emanating from tvs stereo systems and also footsteps here s a graph illustrating the noise reduction qualities of their 3 models.

The noise reduction coefficient of flooring is how much noise is absorbed into the floor material rather than how much is being reflected by it. A room with a high nrc rating eliminates background noise and echoes to help clarify speech. Fact sheet carpeted result in a reduction in noise of over 20 decibels table 1 noise reduction coefficients nrc material noise reduction coefficient approximate carpet with underlay 0 65. The nrc is the percentage of sound that a surface absorbs in other words hits a surface and doesn t reflect back again into the room.

The prices vary depending on the model and square feet you need to cover so a phone call is recommended to suit your. Noise is defined as an unwanted sound judged as loud disruptive or unpleasant it can impact a resident s experience disrupt a classroom or result in communication errors in a healthcare setting. There s no getting around it. For example an nrc rating of 75 means 75 of the sound energy.

Carpet is quieter than hardwood. Number one on the on all counts is. Theaters for example are constructed with a high nrc rating in mind. Flooring for sound reduction carpet.

Nrc noise reduction coefficient measures how well materials stop sound from reflecting how much sound they can absorb.
