Quiet exhaust fan recommendations

Anyone have any type of brand for exact model of a quiet 4-6" exhaust fans?
My roomate's bed is on other side of wall of my grow room. So I'm trying to keep the noise down as much as possible when I start flowering.
My grow tent is 4x4x7 .

No specific recommendations on brand. When you do your searching you are most interested in somes (the way sound is measured in the venting industry).

sones with an "n"

And sones don't directly convert to decibels.

Also quiet is a relative term.
