newbie with these mufflers never used one. Just read about them... I just pulled up this one says it will not reduce the airflow. If you need to reduce your noise level these will do it. I have never seen one wit h1 on the input side and 1 on the output side that's what I what I meant..
Connect them to your fan and ducting and reduce your noise output by up to 25dba without reducing airflow. It doesnt say what end to install it on input, output??

Doesn't make sense. Neoprene is a closed cell foam - no such thing as acoustical neoprene. 25 dB reduction with no reduction in airflow? 3 dB is detectable. 6 dB is perceived as 1/2 as loud. 25 dB is fantastic since dB is a logarithmic scale. The only thing it could really be is neoprene fins baffling the air and slowing it down. Slowing air will reduce noise AND increase wear on the motor. A speed control seems like a much better idea. Cheaper too. Not all fan motors will work with all controllers though.Gro1 8" Air Fan Duct Grow Muffler Sound Deadening - these fully assembled high-performance Duct Mufflers are non-toxic, fire-resistant, and use commercial grade acoustical neoprene foam made specifically for sound deadening

Exactly.I like the remote control option. You dont need to run into the room to shut things down....
Quick set of pics on building the muffler... took about two episodes worth of Storage Wars, mainly 'cause cutting through this metal mesh is a huge pain in the ass. I would not recommend using this shit at all. Hard to work with in general.
8" -> 6" reducer, 3' 8" wrap duct, 1 bag insulation, a 6" collar (to wrap the mesh around), stucco mesh, wire clippers, zip ties and tape.

Wrap the mesh around the 6" collar, zip tie in place.

I put some tape up on the inside of the hard duct so the fiberglass would stay more or less in place, then put the 6" of mesh in the middle. Wrapped the duct around and pushed it a bit flat to slot into place.

Once slotted, stick the 8" -> 6" reducer on the end and tape.

Add to the end of your ducting and the noise level drops dramatically.

Now I can keep the garage door to the house cracked without having to deal with the noise.
