Sound Data
HVAC noise is one of the most prevalent problems in quiet environments. The FabriDuct™ System reduces HVAC sound levels in two ways:
- Hero FabriDuct™ air dispersion products are made of fabrics which do not conduct noise.
- Results show that lower inlet velocities reduce the ambient sound emitted from the system.
The chart below is based on testing results using different vent sizes, a large variety of flow rates and inlet velocities of 125 to 4000 FPM into a 16” diameter FabriDuct™ System.

FabriDuct™ Reduces Ambient Sound within an Environment
Not only does a FabriDuct™ system deliver air quietly, it helps reduce the ambient sound within an environment. The soft flexible fabric acts as a baffle along the ceiling, reducing sound by breaking up small amounts of reflective noise. The benefits of noise reduction will vary between different environments and noise frequencies.
