Those won't work for our case, there is a huge difference between sound dampening and soundproofing, what we need is the latter, sound dampening is important for recording studios and all, but they are poor in soundproofing because acoustic panels have very low-density/mass and thus they won't help much with soundproofing.

In that case: I guess an underground man cave isn't an option?

could you explain this further? how would noise escape up and not to the sides?

It's the same principle they use then building sound barriers (between roads and houses).

yeah a round tube over the vent would direct the sound up.

this could do 4 vents. cut it to 5 feet long

it would direct the sound up.

I own 3 of the vents and they are good but if you stand on the flat roof they are noisy.

this would make the noise go up not out.

also both the vent and this would last a long time.

this is 60 inch by 20 feet

the first was 48 inch by 20 feet.

BTW if these work these would lower your ac use a bit.

4 vents and 1 pipe would be around 3500 usd here in the states.

Still not enough air out the room with them but you could move 8000 - 10000 cfm with 4 of them.
