Insulated ducting helped eliminate some of the wind noise for me. I ran 25ft of 6" insulated ducting for my exhaust and I can't hear sound from the far end. I still hear it where I have regular ducting connected to my filter in the tent, but it seems a little quieter there too.

I have insulated both ends of my inline fan, the fan itself is not noisey. Majority of the noise is like @Kingrow1 said is wind noise.
I used a 25lt buckets packed with rockwool and it worked very effectively, that's when I realised the fan itself is already quiet.

One before and after the fan dropped my output noise to 17db.

i am aiming for as quiet as possible so this plus insulated ducting should hopefully work
