Not sure that I understand everything said here, but interesting audio master class about music, not mumbling. Best heard on earphones or proper loudspeakers.
If your high-frequency hearing range is restricted due to age, then you can’t hear things that other people can. Here’s a real-world problem that I can’t hear. Can you hear it?
Another useful video?
That was an enjoyable watch. I listened but with earbuds and couldn’t hear it. I might try again using my proper headphones and also using my studio monitors. However I think my age plus tinnitus will prevent me from ever hearing the issue. Oh well, c’est la vie.
Incidentally I remember reading a while back how the police were going to use high pitched sound blasting out of some loud speakers to deter youths from hanging around and being antisocial. Seemed a bit unfair on the local dogs to me.
There’s a hearing test online, by the RNID, which I took and was told I have signs of hearing loss, which doesn’t surprise me, at my age. But I thought I had good hearing, and am not aware of hearing difficulties, apart from mumbling films on TV.
Best to take the test in a quiet place with earphones for better accuracy. The voice you hear is VERY quiet!
Many years ago when I helped an elderly rich couple, in their 90s, living in a gated house in town, to catch their cats to have them neutered, I was given the front doors keys when they went with their daughters for a visit back to the UK.
I checked the house to look see if any windows were open after a call from one of the daughters. Everything was OK, and was about to leave when I heard a faint high-pitched noise which seemed to be coming from the house. Went in, and the sound was louder, but not very loud. When I opened the security door to the main body of the house I was well and truly blasted back from where I had come. The noise was debilitating to the point of going crazy! Never heard anything like it! Got out quickly before my ears got damaged!
I listened with earphones of reasonable Bluetooth quality, and with a mini Ipad, and I couldn’t hear the clarinet moving from centre to left to right in the earphones, but was aware that it moved about a bit, but barely!
Interesting test
I used a reasonable quality pair of headphones. for it, sat in a quiet room.
I often have significant difficulty understanding speech, and closing my eyes often helps quite a lot. It’s not the sound, but the processing of it, turning noise into meaning that I struggle with. This has become more difficult as I’ve aged. I also have tinnitus at times (covid made it worse for a while) but not constantly.
I was gratified to get the same result.
However, when I did a frequency test, checking a pair of cheap IEMs, my hearing dropped off markedly over 11kHz.
Whatever: I play bass 
I’m quite aware that the top end of my hearing is gone, but that’s not such a problem. As a guitarist, my amp goes up to 11. 
That test showed I have hearing loss, which I already know - I have a gapin mid-range hearing, which I’ve always had, but of course it gets worse with age. I shall try it later with the hearing aids in 
Get some REAL headphones…!
Slightly above my budget, mine cost€15 at Action
They should try classical music and opera. At normal pitch. Works calming animals so may help with feral youths.
that threw me back to 1990… when Opera (in the guise of The Three Tenors’ concert in Rome) calmed the wild/mad masses of Norfolk youth…
We were visiting family up there a few days later… and the wonderful singing/music made a marked impact… the subject was on everyone’s lips… even the most “unlikely” lads spoke of it… almost in awe …
They introduced it in deprived rural areas in Cumbria several years ago Mainly in places where kids were so desperate for anything to do in the evening that they’d congregate outside the local supermarket and ‘cause a nuisance’, I remember reading about it, but think we emigrated shortly after (although not because of that!).
However, as far as I understand the sound didn’t ‘blast’ because no-one over about fifteen could hear it.
Thinking back to my own teenage schooldays in a picturesque Pennine village, over a comparatively short time we graduated from underage cider drinking to underage beer drinking to Afghani and Moroccan hash to LSD. But to the best of my knowledge, we never upset anyone !!!
Unfortunately today that sort of route would be far more dangerous because everything illicit is so much stronger.
Ha, yes you’re right. Probably not the most apt choice of words.
It was called the Mosquito.

I replied wrongly before, referring to a clarinet moving from centre to left and right in the headphones - that was in another video - this video - where the clarinet is playing. Still can’t tell if it’s moving from side to side in the earphones, even using better earphones than I used before. Age and tinnitus!
I had another go with the RNID test, with my hearing aids in place, and it still said I had hearing loss. How depressing…
I have to use oxygen and an apnoea machine all night, which is tricky with a blocked nose. I spotted Fisherman’s Friends in Lidl, and now I have one (original flavour) at bedtime every night, which I prefer to nasal sprays. The mint ones live in my handbag in case my mouth dries up during the day, and both feature in my meds kit when we travel!
