Super loud! Hard to have a conversion and cook because it’s so loud unless the person is standing right next to you or only like 3 feet away. I bought because of the 900 Cfm it has about 3! Literally my smoke detector goes off all the time!!!its so annoying, I cook a lot, I have 6 children so I am consistently in the kitchen I have never had my fire alarm go off because cooking something on the stove the oven yes! But never the stove and like I said almost every time I cook I say all the time now, I am glad I don’t have close neighbors they would think gosh she is a horrible cook her fire alarm goes off every night at dinner! 
I wouldn’t ever purchase again...hope this helps the next person looking for a hood. One pro it that it looks really good in my kitchen
