I'd recommend door seals to people who made threads here in the past. This time I did it for myself, here's what you NEETs may expect performance-wise.
>thin light seams seen through door cracks
Needs some kinda fill material between the metal track and jamb, if perm I'd use an adhesive
>didn't get neoprene door gaskets, threshold, an automatic door bottom, and metal door
4-6wk lead time and easily X20 the cost
>didn't measure with old stop up
Only thought to measure as I was already prying the old stop off, it could be put back up for future tests
>Hz plot has all these dips!
yeah not much I can do about the cancellations at those dips

>What a proper wall would do for transmission loss
Kinda annoyed annoyed no ones got measurements for sub 50Hz content, especially when they're trying to sell floor decoupling treatments without measurements.

muh green glue

Wow an anon who actually made measurements, holy shit.
What's the turd thing?

>>1140990 is the difference between having >>1140984 then make >>1140984 with green glue between the gypsum sheets.
>The dip at 2KHz is a weakpoint in the materials used
>Green Glue absorbs the issue
>That dip zone happens to be our sensitive spot too
So if we look at both sides using 75dB of pink noise
>75dB reduction at 2KHz but we're +4dB sensitive to it
>say it's 4dB at 2KHz
>39dB reduction at 100Hz but we're -20.5dB sensitive to it
>15dB of 100Hz is leaking out
>29dB reduction at 40Hz but we're -45.53dB sensitive to it
>0.47dB of 40Hz isn't heard lol
So why would one need more attenuation at 'the problem area' when the 100Hz area can be picked up at a 10dB higher level?
I could be wrong, but that is the way I'm interpreting it

Done.

what the fuck is going on in this thread!

>>1142258
measuring transmission loss from NEET rape dungeons, obviously.
Since I have some equipment and free time, I thought I'd test what we tell people here on /diy/ to do.
