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. An NRC of 0.0 …

Sep 23, 2020 · What is an NRC rating and what does it stand for? A Noise Reduction Coefficient – commonly known as NRC – is a single number rating which represents the average of sound …

NRC, or Noise Reduction Coefficient, is a standardized acoustic rating that measures how well a material absorbs sound across mid-range frequencies—typically from 250 Hz to 2000 Hz. The higher …

Mar 7, 2025 · NRC stands for “noise reduction coefficient.” An NRC rating is determined by a third-party laboratory that essentially issues a percentage grade that represents a specific panel’s ability to …

A Noise Reduction Coefficient (NRC) is a single-number rating that attempts to summarize a material's sound absorption abilities. It is calculated by averaging a material’s sound absorption coefficients at …

Feb 22, 2024 · NRC stands for Noise Reduction Coefficient and measures how much of the sounds (on certain frequencies) are absorbed or reflected back into the room. The NRC can be measured for …

Apr 1, 2025 · Typically expressed on a scale from 0 to 1, the NRC value represents the proportion of sound energy that a surface absorbs rather than reflects. An NRC of 0 means the material reflects all …

Jul 11, 2025 · Learn what NRC ratings mean, how to select the right acoustic materials, and avoid design mistakes that ruin sound quality in modern interiors.

Jun 6, 2025 · NRC stands for Noise Reduction Coefficient. It is a numeric rating that indicates how much sound an acoustic material can absorb. The rating ranges from 0.0 to 1.0, where: 1.0 means the …

The NRC value of a surface simply denotes its ability to absorb vs reflect sound. The higher the NRC value, the stronger the sound absorption and the lower the sound reflection in the room.
