As one who can hear these sounds, I can attest to how maddening it is. It's even worse when (most of) the people around you can't hear it, and they don't believe you. Earplugs only make it worse, because they filter out ambient noise that otherwise helps distract you from the incessant hum. Daytime is not as bad as night because of the natural activity sounds of a city. I have read that waves and underwater currents…

Maybe it was this? https://en.wikipedia.org/wiki/K%C3%A1rm%C3%A1n_vortex_street This has been cited as a possible explanation for strange noises in the mountains at various locations and also as a possible cause of the infamous Dyatlov Pass incident.

Why would a humming noise make people go crazy and leave their tents naked, cause a skull fracture and two chest fractures, remove one's eyes and tongue, etc.?

Could an algorithm, like the one used in shazam, be fed a sample set of noises from many different machines/industrial equipment so that we could hopefully be able to take the noises/sound profiles of the things being posted in the comments here and check to see what the most likely source is.

Three people so far have suggested in the comments here it should be "easy" to triangulate it. Note that according to Zug Island's Wikipedia page, "As of April 2013, a Canadian scientist is using sound-level meters and a portable "pentangular array" of cameras and microphones to try to precisely identify the source of the sound, in order to know whom exactly to ask to fix it" and that "the City Council had already sp…

They can triangulate it unless... (puts on tinfoil hat) ... the hum is coming from under the city.

No tinfoil hat needed. It is very possible for some machine at the steel factory to have foundations in a slab of deeper bedrock that becomes more shallow where the noise is more prevalent. The noise would just come from 'everywhere'

They need to deploy a shot spotter that cities use to quickly locate gunfire and dispatch police. https://www.forbes.com/sites/alexknapp/2013/06/28/shotspotte...

With laughable accuracy: http://fox61.com/2013/05/22/fox-ct-investigation-is-costly-g... Part of the problem is multipath due to reflections caused by buildings, hills, trees, etc. Anytime you listen to thunder or fireworks the rumble persists due to reflections off of such things. It's incredibly difficult to algorithmically remove multipath from terrestrial sources.

Correct. At 30 Hz directionality is a pipe dream.

Infrasound can cause weird psychological effects. Fractured bones can be caused by carelessly scrambling over uneven terrain which the campers may have done in terror. Vortex streets can also supposedly be composed of large vortices which are like tornadoes. Maybe the fractured bones could be explained by this as well. Missing eyes and tongues can be caused by wildlife.

Are there any other records of infrasound making people panic like this while camping in the mountains?

The audio on the video was probably added in post...

Could you elaborate on why that is necessarily a problem? Couldn't they have done it losslessly?

Meaning it's just a rendition of a hum, not an actual recording of "the hum".
