"Thank you, Dennis. I can benefit from your experience. I was considering the plywood to evenly distribute, glad to hear experienced others have had the same impulse. "

Chris Stratton replied to Robert Bean's discussion Low velocity consequences in Kitchen Ventilation
"Seems like high velocity and low noise are at odds with each other. And one of the biggest impediments to people using range hoods in their homes is noise. Wouldn't requiring higher velocity exacerbate this problem? Sorry forgive my ignorance but…"
