Exhaust hole making too much noise

[bushmang]

Hello everyone

I have a slight problem thats making me a bit paranoid. Now my room is in the basement and i got a 1m2 window that that extractors blow out of. Then there is about 1.5m tunnel up to the back yard. Now there is a built fixture hung on the window, is made air tight with spray foam, and both isobox extractors one is a isobox tx250 1000m3 and the other one is a isobox tx315 1750m3 both are on charcoals and both are blowing out of the basement window which is located in the ground in the back yard. Now the ducting and extractors are iso (insulated). No silencer since i got two of those bad boys and i have no room for the silencer.

Now how do i fix this noise issue? i was thinking about tracking down some of that music studio foam and puting it down there? what u guys think i should do?

Get a dimmer to slow down your fan speed.

is the noise a buzz or a whir, in other words, is it the noise of the fan rotating, or is the fan not properly installed and it's more of a buzzing sound? Answer that for me and i'll be able to answer you

i hear wind, no rattling or anzthing like that the iso box is mounted on the wall with rubber spacers in between the extractor and the wall. so i dont think the install is a prob. The noise is the sound of big wind coming from the hole thanks for your help
