After applying Soundproofing Sealant to the corners and top, inside the room, The 3x3 room becomes echoing and ringy and when i close the DIY thick door the sound leakage is much greater then before.
Seems to me that until now the sound had a place where to run in the corners and top to the Roxul Insulation, and be absorbed.
However now the sound can't run so it leaks through the door' WeatherProofing foam seal.

Makes sense?

Probably the fumes, move to an area with fresh air.

Yeah, I got a good chuckle on that one.

Is it solipsistic in here, or is it just me?

SomethIng to consider is that In my expirence the quieter the space the more distinctive the remaining sounds become. A noisey room can be just so much white noise, in a quiet room the air rushing through a duct can be irritating. just like me blowing an answer out my $ss.

If you get the room better sealed, you can pressurize it harder, so yes if it only has one place to leak instead of many, that leak would sound more.

And one can definitely get other acoustic problems pop up on you when improving other things, it shouldn't be a reason to go back, rather to go forwards further by fixing.

Don't confuse soundproofing with acoustic treatment. You ahould put absorbers and diffusers and bass traps to deal with ringing, reverberation, bass moding, etc. First, get the room as quiet as you possibly can with soundproofing.

Thanks.
the Foam is this

7/16 thick.
its all the way around the door.
I think if the seal is enough for soundproofing?
Its definitely not made for sound blocking.

The sound pass through the 7/16 rubber foam???
Here is the Rubber Foam around the opening of the door.

If it's an airtight seal, it should be doing its job. The more expensive Zero international adjustable seals are more elaborate version of the same thing.

Are you sure it's though the seal, not just through the entire door?

That foam is a draft stopping product if you are really serious you will want to get adjustable rubber seals like the zero mentioned, see soundproofingcompany.com Turn out the lights in the booth and shine a bright light around outside perimeter of the door to see if you have any gaps in your current setup. A Two person job.
