How much noise does it reduce?

Open Air Cinema tests prove that sound dampening blower boxes can reduce the air blower noise by 20-30%.

Why such a percentage range?

Air blower noise depends on a number of variables:

  • The air blower power.
  • The surface on which an air blower operates (grass, wooden floor, concrete surface).
  • The surrounding objects and their noise resonance.
  • The ability of a muffler to dampen the noise depends on the operational phase: the noise will be louder during the inflation phase and will be less heard during the constant pressure phase.

While 20% of noise reduction may sound insignificant, it actually changes the tone of the air blower noise, pitching it down to lower frequencies and making it more pleasant to your audience's ear.

When your movie night show takes place outdoors and the portable audio system is on, your audience won't notice the air blower noise. The noise becomes more of an issue if the show is taking place indoors.

In such a case, the use of a muffler is highly recommended. Besides noise reduction, Open Air Cinema sound dampening blower box helps protect the air blower from the elements and makes it safer to use.
