LAB TEST RESULTS

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)

Summarized WEAL Lab Test Results

  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.

Acoustic Curtains work best when hanging in loose folds. Allow for stacking space if you want the curtains to clear a window or door.

By sizing the Acoustic Curtains to completely cover side, top and bottom of the windows, you are minimizing the amount of sound that can get through to the other side. Traverse rods allow the fabric to overlap in the center and wrap around the sides to provide as much coverage as possible. When giving us measurements, provide width and length for each curtain. Add additional stacking space if you need the curtain to clear the window on either side.
