@arthurriaf8052: My hearing as a 75 year old man tapers off at about 12,500 Hz.
That being the case, I can hear a hiss that isn't there during your talking passages at the same volume. That rules out the ear pads and phone amplified sounds.
I can hear a very high-pitched sound when in the local bank. It comes from the alarm system. There's an ultrasound from the alarms detector I hear. That must be 15,000 Hz or higher.
I find that odd. Is there such a thing as selected frequency hearing loss? Art 🏍

@Pemialmeida: I heard it immediately but that's because I'm 18. I couldn't listen to a song if it had this frequency noise in the background!
@JP-sb6eb: I have not heard the tone in question, BUT at the end of the video, we hear a version without the tone, and then the music is totality different : better definition and better spatialization. So I do not understand how a tone you can't hear, after after its deletion, can change the sound like this...
@AudioMasterclass replies to @JP-sb6eb: I have a hypothesis that high-frequency information you can't hear can still cause intermodulation distortion in the tweeter in the sounds that you can hear. I may make a video on this and see if commenters have anything to offer.
@johnnaighley9252: At the age of about 16, 18, 20 years old when I several times repaired the CRT colour TV set in our home living room, I could clearly hear whether the fly back oscillator output stage worked or not (frequency 15.625 Hz). The fly back transformer was driven by the beefy power tube called PL 519. Even when watching TV sitting in the armchair I always was able to hear this flyback frequency singing. My father couldn't. Today I also cannot anymore.
@LtSheppardXxL: This was a fun video.. But anyone else here in a sort of strange journey trying to understand why their so finicky and complain about audiobooks having too much distortion in their recordings? lol i think i just hear higher level and maybe lower level issues more than most.

@pr0l0w: That ringing in my right ear. Anyways you got me remembering, that as a child, i could hear that the TV was on, altough i was not in the same room and there might not even have been a program playing. I heard that coil whine. Maybe i still do and all that "tintitus" are all those coils around me in our modern world. Who knows?
Edit - now that i got to the end of the video - whats the frequencys at my right headphone speakers that sound so ringing? To clarify i had drumfur ruptures 3 times at my right ear and there should still be a hole - so it might just be that, but i am still pretty sure that ringing is there. The sound is like comming from left to right and get somehow reflected and echoed from the right side?
@Mar-pi5zm: Yeah, I heard right away.
@andywrollo2915: Eih? All i can hear is really high pitch whining.
@AudioMasterclass replies to @andywrollo2915: Yeah I know, but that's my natural speaking voice.
@chrisantoniou4366: Heard it quite easily though not at the same level I used to hear it with CRTs, although it's hard to say because it depends on the CRT and your distance from it. An interesting aside... I have a CD recording which I was listening to while the TV was on with the sound off, and I could hear the beat signal caused by the difference between the two different frequencies used - a CRT monitor was obviously used in the studio where the recording was made and no one noticed the signal! I could also hear some distortion during the louder bits of music in this clip and I'm wondering if that's due to the 16kHz signal or a separate issue.
@SethRomano: I’m in my early 40s and it’s an absolutely wonderful time in my life. I’m young enough where I can hear that high frequency in both ears very noticeably but old enough to have substantial experience with audio engineering and music. I will enjoy it while it lasts!
@kevinmcgrath3591: im 67 and i could hear it plainly, however it was up loud and i suspect it was a lower harmonic i heard, is this a possibility ?

@TheDesperateFoxCreative: Thank you for this video. It helped me explain my experience to another.
@MOSMASTERING: I'm a mastering engineer and I've tried my best to look after my hearing, but at 42 years old, I know that I've lost some top end in my left ear from a few years of loud cars and clubbing in my youth.
I pray for the day when a drug is released that regrows the delicate ear hairs.
Anyway, I could hear the high frequency when I turned my speakers up. I'm not in the studio at the moment, just listening on some fairly mid range monitors so I didn't know if they'd even reproduce frequenciues that high without cutting off.
I'd guess it was around 16-18 k ?
Anyway, if you can't hear it - you could always check on an analyser for high frequency peaks. Or trust a plugin like Soothe bandpassed to the high end ?
(oh, I didn't get that far - you did show it on an analyser)
Some monitors (some Genelec and Focal makes) claim to reproduce up to and beyond 40khz. You'd only have information there if it was recorded at 88.2khz / 96 Khz.. some people claim that those inaudible frequencies still have an effect on anything below them, but you'd need damn good hearing to notice any difference - especially as newborn babies hearing only goes to 20khz then rapidly drops off as you age. And not many toddlers are listening to classical or rock very loud.
I think the point is that if it CAN go way above 20khz, then getting to 20khz is far easier and more precise. Rather than topping out into distortion.. equally on the low end a sub that can be controlled at 20hz, but the crossover only allows down to 30hz but still well in control.
I miss my subs :(
I'm gonna put them back in the studio when I get some more treatment.

@firebladeclements: Strange thing for me was I felt it somehow but couldn't hear it. It also seemed to smear the mid frequency. None of that appeared on the final run.
The only other thing I've noticed that on, is being by a microwave when running. It throws my equilibrium off and I have to move away. Crazy world stuff right there!
@TrainsAndWellbeing: I couldn't hear it audibly on a conscious level but it was extremely uncomfortable; like a stress response I could feel in my head. I am a migraine sufferer and CRT TV's used to be a trigger so I suspect that the stress I was feeling was the tone.

@rhalleballe: As a young guy, i could hear it pretty well. It really annoyed me heavily. Now i am 64 years old, due to the latest tests my ears cannot hear higher frequences than 10.000 Hz. It is as it is. But - from 10.000 to 15.000Hz its not that much as people may think. Its only a so called quint (five tones in a scale). Its way less than an octave. Keep in mind, from 20Hz to 10.000Hz its 9 Octaves , even more than a piano provides. But from 10.000 to 15.000 its only a little more than half of an octave.

@johnanon6938: Decades back when I did electronic repairs I could hear that tone and more, also back then CRTs weren't the only electronics that gave that tone or slightly higher. Now my upper hearing is around 14.8kHz although any higher and it just blends in with tinnitus cheers to ageing.
@captiveimage: I used to be a bit of a hi-fi buff, and definitely had the experience to pick out some issues with playback in the past.
I'm getting old, however, and I know, having tested my hearing with a signal generator, that I can't hear much above 12 kHz any more. Too many rock-concerts where I was all but deaf for hours after the events can’t have helped, but old age does that to you too, I guess.
It's still worth having 'good' kit, I think. I've got a fabulous pair of Gold Planar GL2000 headphones running off a balanced output headphone DAC/AMP, which I know is a great combination.
I couldn't discern the signal overlay you were describing, it's above my max frequency range, but the headphones still offer a fabulous sound-stage and delicious, rich sound experience that I really enjoy.
I completely agree with you that spending more than a given amount on equipment would be, for me at least, a complete waste of time. Arguably, I could buy better equipment, but the cost-benefit I would enjoy would be minimal, if even discernible. Your objective, practical test clearly demonstrated that the range of frequencies I can hear is much reduced, which comes as no surprise. I would imagine that there are other audio issues with my hearing too. Am I as sensitive to distortion, or noise, or even simple signal clipping that I used to be? My guess is that I’m probably not.
I’ve only just discovered your channel, but it’s become a firm favourite. Thank you for sharing your experience and common sense with us. I’m super impressed with your ability to stay open and unbiased in your reviews.

I can still hear up to around 18Khz (ONLY if the sound level is set high enough). At this frequency it's not so much a defined tone, of course, it's more like an acute pressure inside the ear.😅

@BillyHarvey: Interesting to me I thought I could not hear it (As a guy in my mid 60's), but the final version sounded significantly "cleaner", so maybe there's still some iota of that last delicious octave rattling around in those biological sound sensors.

@ThePlagueGameing: 16K is detectable in a PA system. Ironically you really don't HEAR it you PERCEIVE it BECAUSE psychology you know you increased that frequency with your EQ. At least that's my experience. 😊😊
@cdlong1377: Another great video! This point is excellently demonstrated by the end of A Day In The Life on Sgt Pepper. The Beatles and George Martin put a high frequency tone right before the playout loop. I used to be able to hear it perfectly and now at 48, I cannot. My German Sheppard can hear it, however. And she gets up and runs from the room every time! In this video, I was able to hear some high frequency distortion, but I suppose it must be at a lower frequency, as someone else suggested. Incidentally, I learned over the last 6 years that I have a congenital hearing issue which is now a 50bB loss at 1kHZ. High and low frequencies are normal for someone at my age. I look at it as a sort of built-in eq!
@ralphmckenzie8802: At 68 I have tinnitus in my left ear which creates a "hole" in my hearing at those frequencies. Interestingly it made my tinnitus substantially worse when the music was playing, suggesting that although I can't directly hear the frequency spike some part of my aural system can still detect this, perhaps through the jaw or skull bones?
@Nemura12: I'm 43 years old. New to tur hobby, and since I child, I'm hyper sensitive for everything specifically sound. My sound equipment is The IEM project red by crinacle and a Dac.

@TheBRBvideos: At 72 years old there's no way I'm going to hear the 15Kh tone directly despite having spent many years within the hi-fi and recording industries. What is perhaps interesting though is that I wasn't initially impressed by the choice of music, it seemed a bit heavy on the reverb each time it was played in the main body of the video. At the end though, when it was played without the signal, it sounded a lot cleaner with more natural reverb. Makes me wonder if the 'inaudible' tone wasn't still messing with my perception?
@AudioMasterclass replies to @TheBRBvideos: It's the same track both times, just a doodle exactly as it came out of the keyboard. So yes indeed, the tone might be messing with you.
@TheBRBvideos replies to @TheBRBvideos: Thinking about it, the presence of the artificial 15kHz tone and any harmonics at a relatively high amplitude compared to the music signal could also have caused distortion in my amp and the tweeters in my speakers. I'd have heard the effects even if I couldn't hear the cause, like a carrier wave set too low. Very interesting, thanks for an excellent demo.

@TheEulerID: The moment I saw the CRT, then I realised this was going to be about 15,625 Hz as I recall being able to hear it in my youth. No longer of course.
As far as music is concerned, then the highest note in a normal orchestra is C8 on a piano (about the highest not on a piccolo as well). That corresponds to 4,186 Hz. That's over two octaves down from the accepted range of human hearing. Of course, that's the fundamental, and there are higher harmonics, but for the most part very high frequencies don't play a huge part in most music.

@sambolino44: Definitely not a fan of the creepy droid women. Before I got to the part with the graphic analyzer, I tried it with my own analyzer app on my phone, and sure enough - there it was. Ever since I learned that my hearing stops at around 12k -14k I have been curious about this issue. At first I wondered if maybe it was just my speakers, but the analyzer disproves that notion. I guess if I want to get back into music production I'll have to run everything by my nephew. That spike was easy enough to see on an analyzer, but other problems may not be.
EDIT: Just checked my hearing again with a YouTube video of an audio sweep and I guess it's actually closer to 10k where my hearing stops.

@djlafg58: I'm an 81 yo male who noticed about 10 years back that I was not hearing instruments such as a piccolo, or the high notes of violin or guitars, so I went and got hearing aides specifically for listening to music. What a difference they made to my enjoyment. Despite putting my aides in for the second run through of the tone I could not hear it, so my aides clearly don't get my hearing up to 15Khz. never mind, as you say there are still many octaves of sound to enjoy. On with the music!
@artysanmobile: The modulator was never really audible from the television speaker so much as from the power supply and flyback xformer physically. It was loudest when no sound was present and, like all tones, terribly location sensitive, disappearing with a minute movement of the head.
My hearing is especially acute not as a test instrument, but rather as a musical instrument. I’m unconcerned about technical anomalies I know exist but are inaudible to me. What is really special about my hearing, special enough to warrant high pay in my work, is my knowledge of, and ability to represent, musical balance, the overtone sets that identify instruments. None of those functions require my hearing to be flat to some arbitrary frequency. I don’t know why any music lover would have trouble understanding this.
