I have range hood over gas range. There is wall mounted exterior blower and 8" diameter flex aluminum duct that connects from the blower to the hood. The hood and duct are concealed inside custom built wooden cabinet. The duct is really short, in fact it is no more then 90 degrees elbow. The blower is rather powerful and even if it operates at lowest speed it still causes quite noise in kitchen. I thought about putting some sort of inculation into cabinet that conceals the duct with hope to reduce noise from the blower. What kind of insulation provides maximum sound insulation? Are there any other steps that can reasonable be done to reduce blower noise?
