Hey /sci/, let's talk about bats and sound waves.

I'm really curious and I'd be happy if one of you could solve the mystery I came across. When I was 12 or 13 years old I once hit my head really hard, resulting into a lot of pain and tingling around my head and upperbody. The feeling lasted around 5 or 10 minutes, but ever since then I feel a weird 'zap' sound in my upper spine everytime I'm in range of bats, mostly in woods. First I thought it'd be normal and anybody could 'feel' bats, but when I mentioned it to my friends they gave me weird looks and started doubting me.

(tl;dr) Is it possible for a human being to receive a bats 'signal' (sound waves)

Sorry for my English, I'm a newbie when it comes to foreign languages and science.

everyone can hear their sounds besides old people. you don't hear the full spectrum of course but enough to notice it.

If their chirps have a high enough amplitude you would indeed feel them.

What is the basis for your assumption that your feeling is caused by bats? How did you establish the correlation?

It's fairly easy to explain. Everytime I'm near areas where bats live / pass by, the feeling in my spine tells me the exact direction where the bat is / bats are. The closer they are, they ''louder'' the feelings gets. It's hard to explain, but it's like a radar. It's even easier to tell when I actually see AND feel the bats.

That last sentence is a very strong indicator that it's all in your head. Have you discovered bats with this "sense" of yours without seeing them first or knowing they were there beforehand, with no false alarms? Unless you did, I don't think you have sufficient grounds to assume that you really do sense bats.

Your accident created a resonant cavity. Bats are quite loud but at frquencies outside that of hearing, but your resonant structure turns the sound into a mechanical vibration you feel. Same thing as one tuning fork starting to vibrate when a nearby one is struck.

It may represent some persisting damage too. Go check it out if you live in a socialist country. Ultrasonography might also make it resonate

I always end up sensing them first before I start looking for them ... it's like I pay no attention to my surroundings but suddenly, due to the feeling I get, I start to look around and look for the general direction this sense is pointing to and end up seeing the bats. It's feeling over seeing here.

The term 'vibrate' would describe it well. About the ultrasonography, do you mean a regular machine used in hospitals? I was once in a hospital when I had my first 'migraine attack' and I think they used ultrasonography to check out the veins and arteries around my neck (exterior and interior ones). They had to use ultrasonography several times (around 6 times) and needed 3 doctors to find some interior vein. In the end nothing was found and they just said it'd be migraine. I didn't sense anything when I was in the hospital though.

An image where the pain / tingling from the accident is shown + the current vibration caused by the bats.

It's called "schizophrenia", OP.

Welp, thank you anonymous saviour, I'll visit the nearby psychiatry right away.

Ultrasound is anything above 20kHz. A clinical ultrasonography machine can work at MHz range. A tuneable device, or wiki to find bat echolocation frequency could be of use here...

This. It's testable. And exciting if true.

There's also a strong possibility of confirmation bias.

1. Set up an apparatus to emit various frequencies.
2. Get a friend to select frequencies at random
3. Report any sensations you feel for each frequency
4. Repeat a couple hundred times and see if there's a distinct correlation.
