if u were able to have access to a vibration sensor, u might have been able to test various surfaces like walls, floors, deckings that might be reproducing that resonance. a trick i picked up from the older mech techs, they used to use the valve spanner, essentially a metal rod, and touch it to the ear, like a stethescope, and feel/listen to the inaudible vibes. u get the vibe pattern and a gauge of intensity. u can try that on an aircondition or a fridge just to get an idea how it is. i used to touch it on my ear muffs that had a hard plastic or the hard hat and sumtimes directly on my temple for bone transfer.
u will kinda hear the higher frequencies, but the subharmonics u will more feel it.
Aye, I now remember, it have 3 pcp nearby.Numb3r4 wrote:Is there an oil well with any kind of submersible pump in ground nearby?
Is there any kind of top side production facility?
Could be tinnitus.
You may have a superpower see if you can get in with the Avengers.

Daylight and night, 24/, it's a constant noise I saw Everytime I plug it in. But only in this area.SR wrote:The dayton mic isnt that accurate
Get a real rta to analyse. Also is the freq spike happening at night only?

Of is its coming in by air, try using subfrequencies bass traps

I knew what an oil well was before a water well.
