Does any one know or how to find the decibel level of an exhaust fan in a small restaurant . The fan is loud enough that you can barely hear a conversation. I know these fans are loud ,but I don't know what they are supposed to be. I have searched other places on the "net" but haven't found any answers

You should be able to get the CFM and dB level from the manufacturer. But that's for a new fan that doesn't have worn bearings and isn't covered with grease. You should use a dB or Sound Level Meter to get an actual reading OR there are apps for that.
