The Noise Reduction Coefficient is an average rating of how much sound an acoustic noise reduction foam product can absorb, in other words, how much quiet an enclosed space can be made by a noise reduction product. Acoustic noise reduction foam products absorb sound like a sponge absorbs water, and the NRC tells us how much sound these products can absorb. The higher the NRC, the better the product is at soaking up sound.

The NRC of ordinary melamine noise reduction foam is 0.95 means that 95% of sound in the space is absorbed by melamine noise reduction foam, while the other 5% is reflected. It also reflects the effect of melamine noise reduction foam on noise reduction and sound absorption is very good.

The internal structure of melamine foam

In addition to producing ordinary melamine noise reduction foam, Enda also produces wedge-shaped melamine noise reduction foam and pyramid-shaped melamine noise reduction foam. These special-shaped melamine noise reduction foam can completely absorb and reflect sound inside, especially pyramid-shaped melamine noise reduction foam, the raised pyramid shape makes the sound nowhere to escape, and its NRC index is almost 1.

ENDA noise reduction melamine foam

That is to say, the NRC index of the melamine noise reduction foam is greater than 0.95 and less than or equal to 1, which depends on the shape of the melamine noise reduction foam.
