What NRC rating can timber acoustic panels achieve?

Timber acoustic panels typically achieve NRC (Noise Reduction Coefficient) ratings of 0.60–0.95 depending on type and configuration. Slatted panels with acoustic backing achieve NRC 0.70–0.90, micro-perforated panels achieve NRC 0.60–0.85, and macro-perforated panels achieve NRC 0.75–0.95.

For comparison, exposed concrete has NRC 0.02, plasterboard ceiling NRC 0.05, and carpet NRC 0.30. The NRC value represents the average absorption across 250 Hz, 500 Hz, 1000 Hz, and 2000 Hz.
