What is a good NRC rating?
NRC Categories: Best – 0.90, Better – 0.80, Good – 0.70, Avoid less than 0.70. If the room has a lot of people or equipment, and noise or reverberation would interfere with what they are doing in the room, high noise absorption is very important. Use the Best NRC category of 0.90.
What does an NRC above 1 mean?
The Scale. NRC ratings range from 0 to 1. An NRC of 0 means that the product absorbs no sound. An NRC of 1 means that the product absorbs all sound. The higher the NRC, the better the product is at soaking up sound.
What does NRC 0.75 mean?
Noise Reduction Coefficient Explained
For example, an NRC rating of . 75 means 75% of the sound energy coming in contact with that specific material is absorbed. Simply put, the sound is not reflected back into the room to create noise. A material with an NRC of 0.75 would also be considered 25% reflective.
What is a good NRC rating for acoustic panels?
In comparison, 1-inch foam acoustic panels may have an NRC of only 0.4 on average, so they are still reflecting back as much as 60 percent of the sound waves.

NRC Comparison of Common Surface Materials.
| Surface Material | NRC Rating |
|---|---|
| Acoustic Design Works 1″ acoustic panel | 0.85 |
| Acoustic Design Works 2″ acoustic panel | 1.0 |
Is higher NRC better?
Noise Reduction Coefficient (NRC)
NRC is measured on a scale that ranges from 0 to 1. An NRC of 0 means that the product absorbs no sound. An NRC of 1 means that the product absorbs all sound. The higher the NRC, the better the product is at soaking up the sound.
What does an NRC of 1.05 mean?
The higher the NRC, the better the absorber. The NRC may be thought of as a percentage of absorption per square foot. Sometimes an NRC number is higher than 1.00 (i.e. NRC 1.05).
What is NRC range?
0.0 to 1.0
The noise reduction coefficient (commonly abbreviated NRC) is a single number value ranging from 0.0 to 1.0 that describes the average sound absorption performance of a material.
