the bridge collapse is a red pill that the 'elite' 'architects' were frauds.
and civil engineers weren't doing their jobs either.
same thing with very tall buildings.
the woudl have all blown over in a hurricane wind in a way that was not expected if they did not have counterweights retrofitted . . .
what does this tell you: that the elites gate keeper certain jobs for their own and don't really care if they know what they are doing.
multiple fans running at the same time will create a 'beat'
often that beat is at a bad sub frequency.
so that is why the 'fan' issue is so hard to fix.
if you are an audiophile you understand.
you add a bunch of fans and think that's going to solve things with noise. It might make a beat that you don't like.
So I tend to tune mine so that they don't try to do the same frequency. a beat like that is very bassy .
so I set the processor fan to be a C and the case fane to be a E and make the other on a G . . .
I get a chord instead of a low bass horrific beat.
anyway, it's tricky.
for me there is a beat coming out of the heating vents. why? because there is a great big blower in there. And it makes multiple paths through it.
so what do I do?
I just moved my bed so my head isn't at the peak!
and I don't hear it.
If I'm a few feet over towards the vent I do hear it.
so maybe when you 'hear' the fan you shold perhaps move around and see if there is a better place for you to be while that fan is running?
or if sound is bad in a venue, like at a dead show, you move and it sounds better in a different spot.
