    Sone rating for 45 sf bath w/ 8' high ceiling

    I'm having a hard time relating Sone ratings to a known sound. I don't need a super quiet fan nor do I want an annoyingly loud fan, but how audible is a 2 sone fan?

    I've calc'd my CFM to be in the range of 72-96 CFM.

    Thanks

    Answer: 
    Thank you for your question on the model 784 exhaust fan. A sone is a linear sound measurement where two sones are twice as loud as one sone and threes sones are three times as loud as one, and so on. A sone is approximately equivalent to a modern day refrigerator running.

    Answer: 
    Thank you for your question on exhaust fans. To find the proper fan for a room you would take the square footage of the room and multiply by 1.07. That will give you the absolute minimum CFM needed for a room with an eight foot ceiling. If you have a 10 foot ceiling, multiply your answer by 1.25, a 12 foot ceiling multiply by 1.5 and so on. The optimum CFM would be 1-1/2 to 2 times the minimum.

    The Installation instructions say to use speed controls 78V or 78W but I don't see them on the Accessories pages.

    Answers

    Answer: 
    The 78W & 78V are switches that will work with this fan, but they are not timer switches. They are variable speed control switches. Other switches that will work with this fan are:
    57W
    57V
    59W
    59V
    61W
    61V
    64W
    64V
    69W
    69WL
    69VL
    70TW
    71V
    72W
    72V
    T24H

    Of the switches listed above, the ones that are timers are:
    59W
    59V
    61W
    61V
    64W
    64V
    71V
    T24H

    All of them can be viewed on our website, www.broan.com. They are all listed under the Bath Fans, Accessories. There are several pages of accessories so you may have to look or you can type in the model number into the search field and go right to the one you are interested in.
