Ceramic Floor/Wall Tile Acoustic Properties \u2014 Absorption Coefficients (125Hz\u20134kHz)
Glazed or unglazed ceramic tile on cement substrate. One of the hardest and most reflective surface finishes. Extremely low absorption at all frequencies. Common in bathrooms, kitchens, and commercial spaces where hygiene requirements dominate.
Absorption Coefficients by Octave Band
| Frequency (Hz) | 125 | 250 | 500 | 1000 | 2000 | 4000 |
|---|---|---|---|---|---|---|
| α (absorption) | 0.01 | 0.01 | 0.02 | 0.02 | 0.02 | 0.03 |
RT60 Impact
Ceramic tile is almost perfectly reflective. Rooms with extensive tiling require maximum ceiling absorption to control reverberation
Frequently Asked Questions
What is the NRC of Ceramic Floor/Wall Tile?
Ceramic Floor/Wall Tile has an NRC (Noise Reduction Coefficient) of 0.05, calculated as the arithmetic mean of absorption coefficients at 250, 500, 1000, and 2000 Hz per ASTM C423.
Where is Ceramic Floor/Wall Tile typically used?
Ceramic Floor/Wall Tile is typically used as a floor and wall treatment. Glazed or unglazed ceramic tile on cement substrate.
How much does Ceramic Floor/Wall Tile reduce RT60?
Ceramic tile is almost perfectly reflective. Rooms with extensive tiling require maximum ceiling absorption to control reverberation
