It's hard to copy-and-paste from this document.

With the amount of fetal animal testing, it makes you wonder just what they did this study to find out...
You can't hear infrasound, so you don't realize MOST speakers can't physically emit it.
However, rap concerts have MASSIVE BASS SUBWOOFERS as a standard.
These can utilize infrasound.
These can cause severe bodily harm and no one would notice until it is too late.
You know when one of those intolerable shitbag asshole bikers or box-car drivers goes by with their muffler-less hellwagons goes by and you can feel your lungs bleeding as the air implodes in your fleshy meat sacks?
Those fuckers are actually causing you physical harm in the same way a concert like this or a JET ENGINE would.
Not entirely true. Reproducing ELF requires massive amounts of power at proper SPL. Frequencies thought to affect humans are in the 1.5 HZ and lower area. No transducer can reproduce at high SPL. I’d bank more on microwave frequency a la OP Crimson Mist.
