I've moved to a new build on a very windy site.
The extractor fans in the bathrooms are always on and boost when humidity gets high or the lights are turned on
There are further fans in the utility and kitchen that are either off or (very) on. The utility one I'm unlikely to ever use.
There are external louvred/flapped grilles on the exterior that are exceptionally noisy and rattle and flap in the wind.
If I remove the louvre completely then the pressure the fan in trickle mode does not overcome the gusts of window going the other way into the house so it seems I can't avoid some form of draught flap.
So....getting to the point....what's the quietest method or am I on a hiding to nothing as the continuous trickle will always hold open any draught flap such that it will be caught by the wind?
Maybe something like this?
and then something like this on the outside
