How to Reduce Inline Fan Noise-  Actionable Solutions

Okay, here comes the heart of today’s post, the 8 steps on how to make grow room fan quiet. Let’s start one-by-one

 Isolate The Fans with Carboard/Wooden Box

One of the simplest, but working strategy to lower the noise of fans down is to enclose them with a noise-absorbing surface. We’re talking about DIY boxes made of cardboard, wood or any hard and rigid surface that can absorb sound.

But many can do a mistake of keeping the boxes in direct contact of the fan. But that’s not just a smart way to do that. We suggest you to suspend DIY fan silencer box from the ceiling and walls. Although this process will cost you a little extra effort, but the result will be fabulous. You can use some bungee cords to suspend the boxes over and none of the vibrations and noises will come out of the box.

 Get Your Fan A Speed Controller

Speed controllers are great! Especially when you want to get rid of the shattering noises when the fans run at full swing. What it does is, it gives you the liberty of dimming down the fan and have a control on the noise as well.
