For the price of spray foam, the effort you had to put into doing this, and the time it took (plus the time used to drive to home depot, and the money spent on gas to drive there) I will say this video was exactly what I needed to see to now know I should just cough up the extra $80 and buy the solid door over the hollow door at home depot. Thanks for taking the time, and effort to making and uploading this video.

ASMR - in what way?

You have to seal around and under the door as well. That would have gotten you down some more. Also, the ambient noise in your house is probably around 32dB.

Thank you for this tutorial, i was so frustrated with the noise from outside until i figure out how to close the gaps on my door, and then this foam filler hopefully will improve on what I already did

At the decibel levels measured, that is actually a big improvement. The Decibel scale is not linear so a change of 10 dB would make a sound twice as loud so 2-4 dB at that low of a sound level is significant. For your before check, using a louder sound level likely would have shown a more detectable improvement.

Thanks for posting this, I was researching the same idea. You are saving a lot of people from wasting time. Solid core doors are pretty expensive with everything fitted correctly. Informative either way. You showed before and after DB on your video. I was hoping it would improve it much more than 1 DB ish.

You need to do 3 tests. 1. Music playing 2. Ambient noise, such as a white noise machine or a dryer running. 3. Someone talking. Put on a KZread of someone’s speech. The door will react differently to different sound frequencies. Bass tends to travel through most things, but higher frequencies are drastically cut. From the sound of your video after the foam was installed, your camera is picking up more of the low end than the higher frequencies. The music is definitely not as clear as before. If you used acoustic foam, you’d get better results.

If you put wall board over the insulation on the stairway up to the basement door then you will have sound bouncing of the walls all the way up to the door. Putting some sound dampening panels or material on the walls should help prevent this from happening. Start by hanging quilts or comforters before you buy anything special.

Yeah, looks like he just depleted the cans compressed air supply and only got a bit of foam in it.

Really interesting. I have solid doors, but the "super long zip tie" dip stick is a brilliant idea for all sorts of things. Never occurred to me.

"I'm having a lot of noise come through that door...If somebody's in the basement, kids are screaming..." I almost called the police cos I thought this was a horror film XD

Really appreciate you doing this. I have seen a hollow core door that has been severely damaged. There are internal supports that will not allow the spray foam to get everywhere. Yes you will get a lot in there but will never fully fill it. But, any additional sound deadening can’t hurt.

yes it seems to help a bit. worth it for a few cans and some time. I actually did 2 doors and it's a lot faster when not making a video at the same time!

Hey. Thx for sharing. There are a couple of things that didn't help you there. One is that you need a close cell foam and the big gap can is not the ideal one. It expands a lot but is not dense at all. The other issue is that those doors are not completely open between the chambers. They have cardboard spines across the panels which prevent the 2 faces from collapsing. So even if you had the right foam it's almost imposible to completely fill it up with it. I just not worth all the work. Thank you for sharing cause I am general contractor and had a customer with that exact issue. I think I will just replace the door for them. Good luck!

Yes sealing under the door would reduce sound for sure. Not really practical in this place.

Just curious, why not buy a foam core door? With what you spent on foam you might have saved money.

Good video! Always wondered about doing this until I saw the Inside crazy cardboard maze. But you got a lot in there! Maybe I'll just do an insulation sound board and cover it w wallpaper or fabric and of course the bottom gap. Jeeze all that sound insulation and still?! Like water and drafts it's gets through!

Thanks for doing this. I was thinking about it but seems like it more work than I want to do for the small gains.

Decibels is a non-linear scale. It's a logarithmic scale. A decrease in 3dB is the same as halving the sound/ energy. If these measurements are correct it absolutely does work.

Need weather stripping and door sweep to cut it down even more

You have to do the the bottom and do some weatherstripping where the door hits the frame when closed top and sides and it should be perfect good luck

In the past, I have sprayed foam to fill some frame gaps (not within an enclosed area) and I have noticed some part of the foam mix never expands and precipitates to the bottom of the treated area as a yellow liquid that takes more time to dry up (vs the foam). Any experience if the said liquid may soak the door walls from within and stain the paint finish?

I can tell you the expanding foam can discolour paint if you get it on the outside/surface of the paint. But I doubt it will do so through an MDF board.

It looks like you've also got some gaps between the molding and the walls on the basement side. I would seal those up as well, because I'm sure the sound is coming through the walls there too.

You cannot get an accurate decibel reading like that, as there is background noise on the main floor too. Test that by not playing the music in the basement and you’ll probably get a similar reading (from the background noise). You don’t mention how many cans of spray foam you used. I noticed you had various sizes of cans. Did you notice any warping of the door skins from the foam expanding outwards? Did you wait for the foam to dry between sprays? More details please

@gregs_garage

There is always background noise. The point is to reduce basement noise from coming upstairs. This reduced it by 3-4 db. 3-4 cans. No warping. I didn’t wait just filled it. Don’t overthink it.
