Dear lord Mr Slav. You scared the crap out of me. 7:45. I was already tired, and then I heard something that sounded like someone knocking on my door, and I nearly fell out of my chair.

[@MrLorje]

Same thing here man, I was watching alone in the dark, and the sound through my headphones sounded if it came from my front door, so it scared the shit outta me haha.

[@Scampi95]

Dude I thought someone was at my door and it's late at night, I jumped from my sofa and started panicking ahaha

Sound frequencies are very interesting. A high school teacher of mine did an experiment with us in class where he played a bunch of different frequencies throughout class on a phone app. Each person has a slightly different range of hearing, and younger people tend to be able to hear higher frequencies, which they lose with age. There were frequencies some could hear while others couldn’t. There’s also a concept in physics called object resonance. Basically, every material has a specific frequency at which it can be broken with the least amount of energy input. Everything has a resonance, including the parts that make up your body, such as your eye lenses. In some cases, people have found some “haunted” places where certain machinery there in fact was just sending out frequencies that were close to the resonance of our eyes. This was causing people to see more hallucinations of moving forms at the edges of their vision.

[@aga3852]

When it’s quiet, every once in a while, I start to hear constant static, like I’m hearing the Earth’s frequency. My ears also ring sometimes ring for a few seconds randomly which is apparently normal.

[@bruh6801]

It doesn't happen to me unless it's silent. Like, no sound at all

[@Vableme]

Basic tinnitus, happens to everyone in the whole world. It just your brain doing some shitty stuff. But could be happening due to hearing trauma or injuries from hearing loud sounds constantly that damages your hearing nerves.

[@MolkoKillStyle]

Unfortunatly i always hear a high pitched constant sound so it's never quiet for me :(

[@letherealcs5448]

[@mrm1987]

I also heard pulsating sounds, sometimes with a higher or faster, sometimes with a lower and slower frequencie. Tried to trap down the sound but never found the exact source. Also thought about having tinitus, but since it's only heard in winter moth, I suspect it to be the steam pipes for the heaters in this old house. Now I'm scared of getting nose bleeding and cancer 0o As always, interessting stuff. Love your vids!

The start of this video is what my tinnitus sounds like, exactly. It's 24/7 and intensely loud and completely debilitating. Had it since early 2017 & it's permanent they say with no cure. No one without constant loud tinnitus can ever imagine the depth of daily struggle.
