Hi!
Ah... the noise struggle :)
To try to make it less damaging for my hears, my setup for extraction is a DC fan (a powerfull one, for rack servers) that make a lot of noise at full speed, similar to regular extractors, but the speed is controlled with PWM, so i can adjust it either for the temperature optimal or for the noise optimal condition.
I also put a DIY silencer on the extraction side and between the fan itself and the carbon filter.
The fan managment can be done with an Arduino controller or, if you want to make it easy, a chinese pwm fan controller and a DC power supply. The power supply also serve my other fans for air movement inside the room (no more uneven rh/temp in the room).
I cannot say i am sleeping like a king, but compared to plain AC extractor is another world!
