One of the standout features of acoustic mineral boards is their high Noise Reduction Coefficient (NRC). NRC is a measure of how well a material can absorb sound across a range of frequencies. Typically, acoustic mineral boards boast NRC ratings of 0.70 to 0.95, making them highly effective in minimizing sound transmission. This characteristic is especially beneficial in multi-purpose buildings, where varied activities may occur simultaneously in adjacent spaces.

One of the benefits of mineral fiber ceiling tiles is that they are heavier and denser than the ones made of fiberglass. Because of this feature they are much better at impeding sound travelling from room to room. This feature allows these panels to excel in higher frequency environments. Mineral fiber ceiling tiles will generally have a higher ceiling attenuation class (CAC) and a lower noise reduction coefficient (NRC).
