I can tune external sounds into a white noise. It means I can sleep more or less anywhere, and it freaks my wife out.

A Harrier jump jet once hovered over my head at the British Grand Prix a few years back. It was so loud and violent that it set all the car alarms off in the car park behind us, and it really felt like my ears gave up, waved a white flag and retreated inside my head.

(it was awesome biggrin)

I don’t think people realise how loud they are until you have seen one do a display. First time seeing one at Waddingtion early 2000s and it was so loud it made my chest shake and actually scared me ( was about 6 at the time ).

Regarding blanking noise out I think personally you can to some degree.

Not sure how to word this one. It's it a Health thing... maybe.

Are you able to (without interacting with yourself i.e hands, fingers, external input) stop or restrict noise/ sound entering your ears?

Are humans able?

When there's a loud noise and you do the scrunching thing (vocabulary fail), is that actually restricting soundwaves, or is your mind blanking it out?

Do our ears or minds have a failsafe mode, like a fuse before damage occurs?
Not sure how to explain this (or if everyone can do it) but if I sort of tense, I can hear a 'whooshing' noise that limits external sound. It only happens temporarily. Is this the sort of thing you mean?

I doubt you can stop the physical input, the soundwaves / air pressure or any damage to your eardrum. Your brain can switch off your perception of pain and some people can zone out fairly easily when they need to. The scrunching thing is anticipation of forthcoming pain rather than pain management isn't it?

As an a/c owner at Biggin Hill I was able to get pretty close to the Vulcan taking off at one of the airshows. Never heard a noise like it

Oh bloodyhell, I remember that happening to me. Was at the Superbikes at Brands Hatch one summer and there was a Harrier display during one of the breaks. JEEEEZus that was loud. I was way too close while the thing was hovering !

I remember being at Biggin Hill and seeing the Vulcan take off into a vertical climb (as I remember it - think it was c50 years ago now?). The ground shook and so did everyone and everything in the area. Incredible!

Aye, I was at Farnborough Air Show in (I think) 1985 and witnessed a F15 taking off. I can attest to the chest-shaking thing!

It's not mine, but is this one of the fastest derails on PH?

Have a read up about Mercedes presafe sound - a beep before airbag deployment that causes you ears to tense up in a protective manner.

I attended the British GP in 2004, the start was something to behold, all those howling V10’s , maybe not up to a Harrier, but it impressed me!

My sister fell asleep at a rock concert, so anything is possible!

Some years back I attended a Nationals Championship dragster event in the States, I was lucky enough to be trackside and near the start line.

Those dragsters have more horsepower than the first six rows of a F1 grid, and there’s 2 of them taking off at the same time.

I felt like I had been assaulted and that was with ear defenders, my internal organs were shaken.

I don’t think you can protect your hearing by bracing for it, perhaps you just prepare your senses for the noise.

I've dozed off in a few engine rooms, even with ear defenders on some of them are noisy enough that I sense the noise through bone conduction, then there's the heat and vibration. It blends into the background.

I’ve woken up once on a flight and I was completely deaf for about 5 seconds, it’s almost as if my brain had switched my hearing off during my sleep and it took a few seconds to switch back on after I had woken.
To be honest I was as pissed as a mattress so that might have had something to do with it.

This.

Puckering your earholes!

Regarding Harriers. A truly epic sound. Gods of thunder.
Your ears lave, essentially, a lever between the eardrum and the sensory apparatus. By moving the fulcrum it can attenuate the sound level you get to hear.

This lets you hear things like rubbing your fingers together while also being able to hear a rock concert. It's also why you have tight ears after leaving a gig.

I was lucky enough to be hosted by Budweiser at an Atlanta drag strip, can't remember which one. I was given a pit tour and talk with one of the teams as they finished rebuilding an engine then given ear defenders as they ran it up. Walked to the start line with them and was close enough, like you, to feel the noise and vibration go through my body. Awesome and terrifying at the same time.
And I could then understand why some of the crew wore gas masks.

You are tensing your tensor typani muscle in your ear.

I do this all the time, usually to the drum pattern of the song I'm listening to at the time.

Only a relatively small perecentage of people can do it.

Whatever the mechanism may be, I can confirm that my ears have a limiter. A long time ago I had Bell's Palsy which paralysed one side of my face for weeks. Even now, more than twenty years later, my facial muscles are different left vs right.

Anyway, during this time when I had to close my left eye by hand and use sticky tape to keep it closed at night, I went to a music event - not a rock concert but IIRC, one of the last concerts given by Chris Barber and his Jazz Band. As is the way of these things it was loud despite being largely acoustic but one of the support acts did have some amplification and I found my left ear physically hurting unless I blocked my ear with my finger. The right ear was fine but whatever mechanism there is to protect the ear from excessive noise, was paralysed along with all the other muscles on that side.
