Due to lack ceiling space of my bathroom, I can not install those low noise type of ventilation fan, so I have installed 3 sones ventilation fan on interior wall of bathroom, but the noise is quite loud especially night time.
My questions
1. Is any low noise inner wall mount ventilation I can buy?
2. Can I modify that fan to low noise DC type fan?
Thanks
