the loudness of the equipment is most likely never a problem. The frequency however is a different thing and you can't hear it to kno. You have to watch the reaction when you turn a machine on. We had a Cocker Spaniel that would go ballistic if you turned on one vacuum cleaner but had no problem with the other one but to us they sounded the same.
