Suspended Acoustic Baffle Acoustic Properties \u2014 Absorption Coefficients (125Hz\u20134kHz)
Vertically hung panels of mineral wool, polyester, or metal (perforated) suspended from the soffit. Absorb sound on both faces for high effective absorption. Used when the soffit is exposed or when services prevent a full suspended ceiling.
Absorption Coefficients by Octave Band
| Frequency (Hz) | 125 | 250 | 500 | 1000 | 2000 | 4000 |
|---|---|---|---|---|---|---|
| α (absorption) | 0.30 | 0.70 | 0.95 | 1.00 | 1.00 | 0.95 |
RT60 Impact
Installing 15m² of baffles (both faces exposed) in a 100m³ room reduces RT60 by approximately 0.55s at 500Hz

Frequently Asked Questions
What is the NRC of Suspended Acoustic Baffle?
Suspended Acoustic Baffle has an NRC (Noise Reduction Coefficient) of 0.90, calculated as the arithmetic mean of absorption coefficients at 250, 500, 1000, and 2000 Hz per ASTM C423.
Where is Suspended Acoustic Baffle typically used?
Suspended Acoustic Baffle is typically used as a ceiling (suspended) treatment. Vertically hung panels of mineral wool, polyester, or metal (perforated) suspended from the soffit.
How much does Suspended Acoustic Baffle reduce RT60?
Installing 15m² of baffles (both faces exposed) in a 100m³ room reduces RT60 by approximately 0.55s at 500Hz
