Nrc tells you how much sound a ceiling panel will absorb thereby lessening the noise within a room.
Nrc ceiling tile.
Cac ceiling attenuation class is a standard measurement of a ceiling system s ability to block sound between two closed spaces cac values of 35 or greater are recommended to achieve speech privacy.
Nrc noise reduction coefficient is a standard measurement for a material s acoustical absorption ranging from 0 00 no absorption to 1 00 total absorption.
Noise reduction coefficient nrc and ceiling attenuation class cac.
For example the nrc rating of ceiling tiles will vary by the the type of material used.
Nrc and cac ratings.
The symphony m mineral fiber ceiling panels available in a high nrc up to 0 80 option combine a superior finish and exceptional durability.

Note that the nrc ratings of these may vary.
A standard acoustical ceiling nrc 0 55 will normally have an ac of 150.
Cac indicates the ceiling s ability to prevent airborne sound from traveling between adjacent rooms when the dividing wall does not connect with the structural ceiling which ranges from 0 up to 40 45 for ceiling.
Standard nrc ceiling tiles are designed for spaces where controlling sound levels is an important but not a design driving requirement.
Nrc noise reduction coefficient is a standard measurement for a material s acoustical absorption ranging from 0 00 no absorption to 1 00 total absorption.
Fine textured and mold resistant they offer superior sag resistance and high light reflectance values.
Mars high nrc acoustical ceiling panels are designed to offer the highest standard in noise reduction nrc or noise isolation 40 cac.
This chart is simply an estimate for each material and may greater or less depending on how it is made and the type of material used.
High nrc ceiling tiles are highly sound absorbing and offer superb acoustical performance for a variety of applications such as large open office spaces computer rooms auditoriums or any space where a short reverberation time and same room speech intelligibility are essential.
Cac ceiling attenuation class is a standard measurement of a ceiling system s ability to block sound between two closed spaces cac values of 35 or greater are recommended to achieve speech privacy.
When evaluating performance in acoustic drop ceiling tiles you ll want to reference two general ratings.
Defined by astm 1111 the attenuation of sound that travels over a divider and reflects off of the ceiling is measured at human speech frequencies.
Their durability performance and attractiveness make them an ideal choice for an array of spaces.
These acoustic ceilings deliver good sound absorption ceiling tiles with standard sound absorption are offered in a wide range of design options from classic white to inspiring eye catching designs that make.
Ceilings best suited for use in the open office have ac values of 170 or greater.
