Carpet Noise Reduction Coefficient

Here s some hard data.

Carpet noise reduction coefficient. Nrc stands for noise reduction coefficient and is the standard rating for how well a material absorbs sound. Flooring for sound reduction carpet. The prices vary depending on the model and square feet you need to cover so a phone call is recommended to suit your. If the carpet is installed with an underlay its nrc rating will almost double.

A room with a high nrc rating eliminates background noise and echoes to help clarify speech. Carpet having an. So a carpet on rubber underlay could easily have an. 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.

Number one on the on all counts is. Independent laboratory tests show that carpet and textile composite flooring control noise more effectively than any other floor covering. Typically the nrc rating of a material is viewed as a percentage. There s no getting around it.

Nrc noise reduction coefficient measures how well materials stop sound from reflecting how much sound they can absorb. For example an nrc rating of 75 means 75 of the sound energy. Even very thick concrete walls will attenuate sound and may. 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.

Different materials have different nrc ratings that range from 0 00 1 00. Nrc ratings of common room finishes are provided in table 1. Even so no flooring material can provide all of the necessary acoustical management within a space. Carpet is quieter than hardwood.

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. 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. 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. Carpet is a softer surface which means it absorbs noise while hardwood reflects it that noise of course being footsteps.

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. This is more conceptual than physically achievable. Theaters for example are constructed with a high nrc rating in mind. The noise reduction coefficient commonly abbreviated nrc is a single number value ranging from 0 0 1 0 that describes the average sound absorption performance of a material an nrc of 0 0 indicates the object does not attenuate mid frequency sounds but rather reflects sound energy.

Carpet has a noise reduction coefficient of 40 to 50 much higher than hardwood s 40 to 50.
