My backyard backs in to a strip mall with an auto mechanic shop. We hear a high pitch sound some times of the day and when we step outside to inspect, we only hear a different sound from the shop behind - a typical machine running, but not necessarily unpleasant. Turns out the walls are able to mask the lower pitch sound somehow and let in only the unpleasant higher pitch sound to the inside of the house. I am not sure how to explain it to the shop owner, but we are just going to ignore it for now. I guess I need to look into insulation options :)
- jml7c5 6y agoHave you checked for windows resonating? It would be surprising if walls were acting as a high-pass filter. Could also be electronic noise. I wonder what the machine is.
- heavenlyblue 6y agoDo you think the high-pitch sound reflects from the house opposite to the windows?
- abakker 6y agoAir powered die grinder, drill, or impact gun. Or, if it sounds real choppy, maybe an AC TIG welder. I’d bet die grinder. They’re not used all the time, and they have VERY high rpm sounds which are always terrible.
