you can get a premade for roughly $50 that i gotta think will reduce the noise more than 6 db. that said, thanks for making the video. u saaved me the trouble of trying this myself.
Did you get a pre made silencer? I’m working on a home studio and not sure if I should buy the $60 premade ones on Amazon or try to make a big baffle box…
Is your sound meter calibrated? Because the air noise was the same as or less than your voice. Seems like it would be closer to 60-70 dB... But the 5-6 dB drop is probably the more important factor here. Thanks for posting this video.
How about a large coffee fan lined with that polyfill inside a cardboard box. With the can being wrapped with something like a carpet. How does that sound to use guys?
3db is the standard for half power in electronics. Audio ts about 10 depending on frequency. At the register its even less. This was at the duct muffler register was even less .
Price wise. It's a little cheaper to build. Most commercial units reduce air flow to much with the triangular foam. With this you can adjust the poly fill to your liking for specific frequencies.
@stem_saving1644 you know a lot of folks these days are as useless as can be. I would include myself but I actually find videos like yours to help. Like you said in a previous comment it helps because you can control how much material goes vs buying a pre made one that already has what they think is enough.

If you make you own you have control of the sound absorbing material
If we used sound insulation, would this be more effective?
Not sure what sound insulation is or what its characteristics are.
Defo if u have all the tools

Not calibrated. It's more of a relative measurement to show how it can reduce duct noise.
Good work very nice!!
I like the design! But what did the costing on your materials come out to?
Less than 40$.

Makes me wanna spend the money
And how exactly was the noise cut in half by a reduction from 96 to 91 db?
3db is the standard for half power in electronics. Audio ts about 10 depending on frequency. At the register its even less. This was at the duct muffler register was even less .
DB is a log scale.
yes it is, by definition.
It may reduce the noise, but if the source is a bathroom with steam from the shower, that thing will act as a nice condenser ! LOL.
Not sure what bathroom exhaust fan has a 6" duct. If you have that in your house you have bigger problems
Think it's cheaper to just buy it ready made.

Man fuck all that...
Don't like that work?

@lizgaby9761 most of the channels are talking heads and don't show you how to do anything. They just talk. I try to share what I have learned.
@stem_saving1644 yup and thanks! I'll be doing this, this weekend.
