Human hearing can't really localise sounds below 100hz-ish, but it should certainly be possible to triangulate this 35hz hum with microphones.
Probably even easier ways to rule out the cause - turn the furnace off and see if the hum stops? Seems like the cause is known in this case but they just don't want to address it
- snovv_crash 10y agoOften blast furnaces and smelters can't be turned off.
- kwhitefoot 10y agoTrue but they can be turned "up" or "down". Reducing the air flow to the lowest value that can be sustained for, say, 12 hours would give an opportunity to find out if the intensity and type of noise has changed. Do that a few times and see if it is repeatable.
