SoundBarrier™ — Sound Pressure Levels
We tested our SoundBarrier™ with a .750” (19.1
mm) Air Miser™ air wipe (without material) at our factory
to determine general noise reduction results that could be
expected in use. The sound pressure test was conducted at
approximately 6' (1.83 m) at an ambient sound pressure of
68 dB.
