Sounds like you're at the node of some industrial equipment sound pollution Frank, at first reading! Some reports have put quite a distance between source and hearer. One particular one was a large container vessel in port miles and miles away -that was finally tracked down. Autumn dryer fans on farms harvesting are another 'seasonal' - not that this need apply to you- but it happens. No, it doesn't have to be esoteric but its' persistent [and on/off] characteristic gives it dodgy label ere long, for many. [Not to mention official disinterest, so much of the time]
