I think that window frame ventilators are louder than a controlled residential ventilation system, because they are basically holes in the window through which outdoor noises can enter the house, like with an open window. A controlled residential ventilation system does not cause drafts and does not make any noise at normal performance. If you run it at higher power once, you only hear it at the device. Did this architect explain the hygiene problem?
