A STC rating describes the average number of decibels blocked by a material.
Our STC Sound Blocking curtains work due their inner linings. These linings are specialized, proprietary vinyl's made exclusively for Quiet Curtains. The face fabrics used to construct the curtains have little impact on sound blocking. See the Table below for recommended face fabrics.

Under normal conditions, the following will serve adequately well as a general guide on the impact of variances in sound pressure levels:
- 1 dB change is imperceptible
- 3 dB change is just perceptible
- 5 dB change is clearly perceptible
- 10 dB change is substantial (halves or doubles noise heard)
| Sound Absorption Results NRC's | ||
| Acoustic Quiet Curtains | Low | High |
| Crescent Velour | .85 NRC | 1.0 NRC |
| Vara Velvet | .75 NRC | .90 NRC |
| Overture | .65 NRC | .80 NRC |
| Visa Velvet | .55 NRC | .70 NRC |
| Nova Suede | .50 NRC | .65 NRC |
| Solitaire | .40 NRC | .65 NRC |
The NRC range is a function of curtain construction. The highest NRC's are Ripplefold 220% construction. The lowest NRC's are Ripplefold 160% construction. Pleated curtains fall in the mid-range depending on fullness. Double sided soft-fold curtains perform similarly to Ripplefolds.
