"Consonance calibration": note that this term doesn't refer just to the fact that we tend to tolerate an out-of-tune bass in the context of higher frequency notes. It's referring to the way it feels when the bass is switched from being out-of-tune to being in-tune -- that is, the way we calibrate to the out-of-tune bass, and when confronted with the in-tune bass, it sounds out of tune until we re-calibrate.

Not totally sure if it has to do with perfect pitch, asd, or just not wearing headphones, but for me it sounded super off until you corrected the key, then it instantly felt better to my ear. I can't say I noticed any necessity to "re-calibrate" in this specific instance, however I think I understand what you're speaking about. I've learned anything/everything backwards and am in no way proficient musically, but I decided to make arrangements anyway because I have perfect pitch for some reason and felt like making music things or whatever. Long story short messing around with all the knobs and settings and things trying to learn what does what I think I've unintentionally reproduced the effect you're referring to fairly often when quickly adjusting pitch while audio is playing, and you kind of have to mentally re-adjust to the tune... Is this what you're getting at? Sorry if this all sounds like nonsense, I can't even read sheet music, but I like making the pretty doot doots... Your series here has helped me to understand things better, especially in regards to why I would ever use Panning rather than just going "all ears get all noise because it good noise." I am not a very normal person, sorry. Thanks.

@@-Nudal hmmm yeah not sure if it's the same thing. I wonder if your perfect pitch means you won't hear this effect, since it makes sense that you wouldn't ever "bend" the notes to where they are "supposed" to be? Those of us without perfect pitch might be better at believing that the notes are in tune when they aren't. Maybe it could be triggered in you if the pitch was just a tiny bit out, instead of a whole half step out?

There are some weird things that happen at lower bass frequencies, it's common to have to hand tune your bass notes in mixing in order for it to be perceived as in tune. Mathematically in tune bass notes sometimes do not sound that way

I guess it's also a similar effect to when you play a song pitch shifted upwards quite a bit into a different key and then listen to it for a while. When you shift it back down to the original key, the song which originally sounded okay now sounds terrible compared to the pitch shifted version. I noticed that this only really works if it's a song you know but you haven't overplayed.

I think this might just be the fact that very high notes don't have any clashing overtones with the very low notes. The higher harmonics of the very low notes are quiet, so they don't clash with the high pitch notes, and likewise there aren't many audible overtones on the high notes because many of them go beyond the human hearing range. So, because there aren't any perceptible clashes between the overtones of the two pitches, they don't sound at all dissonant. I noticed this a long time ago when playing around on the piano, and I noticed that if you take a dissonant interval like the minor ninth, and keep raising the upper note by an octave, the perceived interval gets less and less dissonant

I experience the “consonance calibration effect” consistently with very dull bass tones. Low frequency pure tones sound higher than they are, lacking upper harmonics to help our ears calibrate. I have absolute pitch; a bassline of a familiar song coming through a wall very often sounds like the wrong key (too high), until I hear some upper parts with it and realize it’s this effect again. Audio engineers know that a loud pure tone seems to sound lower in pitch than the same tone played softer. I think this is due to the ‘swing’ of the eardrum. The farther it has to swing, the lower the pitch feels. (Fantastic series! Great work.)

I think you're onto something with that Consonance Calibration Effect. I'm not a professional, but general knowledge has told me this: Our brains like patterns, and we like to know what's coming ahead of time. When we hear the tune the first time, there's definitely a sense of "something ain't right here" (for me at least) but by the time the next loop occurs, our brains have prepared for that off key note, and even accepted it as normal. When you fix the pitch, you disrupt that pattern again, causing the "correct" version to sound incorrect for the first loop. Again, on the second loop, we hear the song correctly as the pattern has repeated. And that tune is really good. If anyone does a full cover of it I'd wanna hear it. Off-pitch and all.

At the beginning of my electronic music production explorations, I didn't really get that in Techno music it happens quite often that the bassline is composed of only one note. The rhythm makes everything. Knowing that now, I can hear way better the actual melody pattern of the bass. Whereas beforehand, I thought and was convinced of those having much more melodic variations. This leads me to think now that repetition of the same note can actually be super good for a track and for the listener. As in we just go unintentionally with the melody variation we are more inclined to. Repetition of the same note can leave more freedom to the listener for completing eventually the melody with the variation of their convenience. Sounds good to me. =D

No Idea if it has any scientfic name. People like both ones, your brain just gets confused while it adjust to either of those.

After listening it for a while and listening it in a proper way (quiet rooom, good headphones) you will listen those parts. After you "memorized them" if you play the music anywhere at any wuality you will "hear" it, even if others don't. i started realizing it more often with a speaker from a car that was missing frequencies on road. I still could listen to some parts and if i asked someone if was there they likely didn't noticed is pretty awesome

The amazing thing to me is how you can turn music down and listen for a while, and it will seem to be at a "normal" level. Then you turn it down some more; it seems quiet, but after a few minutes it again seems "normal". Then you turn it down again, etc. It's amazing how quiet you can get it. And the brain seems to "fill in" a lot of the details, as you suggest.

Great series! Thank you! I suspect that the headphone porch shift might be the door effect. As you move the sound source away from the destination each sound wave cycle takes a little longer to reach your ear giving the illusion of falling pitch. "real world" Doppler seldom begins directly in contact with your ears. We usually hear Doppler approaching, passing and the receding so pitch goes up as sound source approaches and goes down when it recedes. With headphone there is no approach so it sounds unfamiliar. That's my guess anyway!

Late to the party, but that was my guess as well: a type of Doppler Shift as the sound source moves/is moved further away, thus taking more time to reach your ears than what you were just listening to. I didn't try it, but does it work in reverse? Start by listening with the headphones in front of you and then put them on. I suspect the sound will shift up in perceived pitch. Great series BTW.

other thing i am paying attention (is more on the brain education level (neurological) than ear by itself) is that when you listened a music once, you can probably don't like it on a show, but if everytime you listened the opening or ending and it have the same music, you will start to like it. i saw this fenomenon with anime and tv shows, at start you can say "its bad", doesn't fit properly or "the one from last season was better", but once you get used to it and (it is a good show so you enjoy viewing it) you will likely blend the emotion of beeing a good thing with the music and will consider the music as good. It can happened on parties too as you can record a good emotion or good memory and record something with it.(like the flash and beep sound) it is used to train you brain in a dificcult cenario "if you cry, snap your fingers", if you do this every time, one day you snap your fingers and will cry with no reason. your brain got used to one be coorelated to the other and if one is present, it thinks the other will be there soon". It can extend to traumas and other things, but i have to say, is just me saying and observing. It is not a scientific research done by me!

I just HAD to binge watch (listen to) all 5 parts. They are EXTREMELY well done!!! I was getting ready to criticize you for leaving out one; when you finally did the headphone pitch shift effect. This has nothing to do with headphones! Above a certain (loud) volume, our ears perceive louder sounds as moving to a higher pitch as well as getting louder. I have always been more susceptible to this than most other people. This is why I will never be able to properly tune an instrument that is loud. I don't know anything technical about why this happens, but it does. If you take that same tone and play it through speakers and make it uncomfortably loud, like 100db or so, you will perceive the pitch change. The reason it seems to work better through headphones is because it's much easier to achieve a loud enough sound in your ears with headphones than speakers.

That was a fantastic series... the editing and presentation were excellent! I watched through the entire series in one shot, and I learned a few things along the way. The first thing I realized is that I should have disabled the Windows audio enhancements for my A/V editing a long time ago. I almost gave up on the first episode when I heard downmixing of tones in both channels for the binaural beats test... disabling Windows sound enhancements AND the "SBX Pro Studio" settings on my SoundBlaster ZxR did the trick! If you have a running list for a follow-up series, then I have a strange one for you: auditory-visual synesthesia. I have experienced this phenomenon all of my life. Sudden, loud noises cause me to see bright flashes of light or color, usually in patterns such as fractals or pinpoint stars. It's usually more prevalent when I'm very relaxed or nearing sleep, but it can occur anytime there is an unexpected loud sound in my nearby environment (e.g., creaking/popping of household walls or roof rafters at night, a book dropped on a floor, etc). It's definitely a rare condition and would probably be difficult to elicit in listeners, but it's an interesting phenomenon. Cheers! 👍 --QM

I've noticed the drop in pitch when removing headphones for quite a while now. I was wondering if it was something to do with the Doppler Effect? - when the sound source (the headphone) is moved away from the ears, the pitch will drop due to this movement producing the Doppler Effect. Maybe this momentary drop in pitch colours ones perception of the pitch even when the headphones are static. Maybe as this lower version of the sound is the initial sound heard in the "new mode" of listening (listening now in the new acoustic environment of the room) it takes president becoming the new overall perceived pitch of the sound source, relatively lower than before. I wonder if it's the combination of these contrasts - the contrast of the sudden change in acoustics as well as pitch that signals to the brain that something important has happened and latches on to perpetually hearing the sound as relatively lower to draw our attention to it? does that make sense?

Here's my hypothesis (it doesn't rise to the level of theory): I hear low sine waves as sharper than they actually are. In a more complex tone, the harmonics generally keep this effect in check, but a strong fundamental can still put a slight upward pressure on my pitch perception. Taking off the headphones, that fundamental is lost very quickly as they lose the benefit of the proximity effect, which means the perceived-as-sharp fundamental falls away, and the pitch seems to glide down to the pitch it actually is -- I had just been hearing it as 15 or 25 cents sharp all that time I had the headphones on.

Sometimes instead of music, I hear distant sirens that continuously overlap each other. The effect can be so convincing that the only way I know for sure the sounds I'm hearing aren't really sirens is that they never get closer or farther away.

I know someone who’s had a similar thing happened to them. I’ve had a similar phenomenon happened to me especially when I’m about to go to sleep, where it will sound like the white noise of a airplane or car dips down in volume for about 500 ms and then comes back up to normal volume.

And about the headphone removal effect, I experience this a lot. I spend a lot of time on my keyboard to set song arrangements with arpeggios. When the arpeggios are still running and I take my headphones off (semi-opened ones), I always have this impression of pitch falling. It even confused me sometimes and I put them in again to double-check the sound was still ok. Now I'm at least aware this is a psychoacoustic effect. But yes, that's definitely something I experience often.

Loved the series. I am off to see if stereo widening consistently does what it did on my dolby surround loudspeakers. As you widened the music moved to the back speakers. You were talking about 3D sound and this may be the formula more than using surround mode on my DAW. Also thank you for telling me I am not alone in making adjustments on a mute layer for a while before I realize it is just perceived bias.

Nice series! (I *believe* it's a known phenomena that louder sounds sound higher in pitch than quieter ones. I heard about it many years ago in a story about the artist 'Sting' performing a song in the recording studio. Folks in the booth consistently heard Sting singing slightly out of tune, which annoyed him, since he was quite confident he was in key. Eventually, they figured out that Sting was indeed singing in tune, but some aspect of the monitoring system they were using (perhaps just listening to Sting turned way up in relation to the rest of the mix) gave the impression that he was ever so slightly sharp or flat.) I wonder if it's some sort of imaginary Doppler effect. If a tone suddenly gets quieter without otherwise changing, perhaps our brain assumes it's receding from us in space, and "expects" a bit of Doppler shift. I may have that exactly backwards, however.

i just loved this series of audio illusion videos!! and it would be great to ho see a part 6!! btw regarding the consonance tuning effect i believe is due to the harmonics of the bass line, as you go higher, the harmonics get smaller and therefore are more easily consonant with the half sharp melody, you can notice this by doing a Cmaj chord and any other major chord not belonging to the key and play them in the same octave and then start separating them by an octave each time more and more, as they get further apart they feel more consonant with each other. And the headphone pitch-shift effect i think is caused/related to the doppler effect i guess? Anyways thank you so much for these videos and i´ll be waiting eagerly fot the part 6 to come out!!

Thanks Jorge -- glad you liked them. Thanks for the theories -- I don't think that the harmonics are sufficient to explain the C.C. effect -- the same thing happens with pure sine tones (in fact the effect is more intense in one way: it seems to make the lower tones change pitch when the higher tone shifts key!) I wonder if it's more about the fact that in reality our pitch perception doesn't quite match a true log-base-2 scale. Re: the Doppler theory: I'm not sure there is enough speed (relative to the speed of sound) involved here. If I had to guess I'd say that the shift of timbre from the fundamental to the overtones which happens when the headphones are taken off might affect our pitch perception?

I really liked this! I once found an audio illusion myself, which nobody seems to talk about. But, If you take a square wave, and duty cycle modulate it from 0%-100% with a slow sawtooth LFO (square playing C4 with about 1Hz-4Hz LFO frequency), it begins to sound a lot like two sawtooth oscillators detuned and beating against each other, despite it only being a square wave cycling in pulse width. I did some further playing around, and I realized you could create the same 0%-100% duty cycle modulated wave by taking a sawtooth playing a note, and another slightly detuned, and invert the detuned one. That led me to me realize that a lot of music composed for the Commodore 64 that used a duty cycle modulated square wave did so to emulate a detuned sawtooth, because of the limited amount of voices (3) it has to work with. Now, I encourage you to try this yourself, it's pretty interesting.

I think the consonance calibration worked so well because it was using a blues-y scale. For an example of why this works, see what the intervals of each key are when you play the same note but for both keys: Melody: | Bass: nat. 2nd | minor 3rd minor 3rd | major 3rd major 3rd | perf. 4th perf. 4th | tritone tritone | perf. 5th nat. 6th | dom. 7th A lot of common notes in this style have notes one semitone above them that won't sound bad either. of course, a few are strange like union | flat 2nd perf. 5th | flat 6th But, couple those line-ups from before, with the fact that it's pretty normal for a bass to hit the tritone as the melody hits a 5th, or the bass to hit a minor 3rd when the melody is major, ect. and you get a pretty consonant song. Anyways, i found this a really interesting effect to use in making songs - especially if you want a "slightly off" feeling. Edit: mixed up the bass and melody

Also if you need representative stats - I'm a musician as well, with a good ear to learn music on the fly but not with the perfect pitch. Your series was a great adventure and lots of fun - I actually was about to ask what was the $85 mic because sound was great, but I was swallowed by conformation bias anyway :) - Fat sub is on the way of course and I'll looking forward for new content. All the best! Stay safe!

I listened to each and every video, on headphones. I have always paid great attention to what I can hear. My father was a BBC sound engineer. He pointed out that tilting your head down increases the HF audibility of sounds coming from the horizontal direction. We took that to be an effect that would help forest dweller detect things coming when they were looking down. It works very well when listening to music - but only if you are in the front row. Human bodies between you and the instrument lessen the effect.

The consonance calibration effect is something I've noticed as well. I've heard it mentioned before elsewhere but I can't remember what it's called. It can be demonstrated on any instrument with a decent range, like a piano or even a guitar. Play an open low E string on your guitar and a melody above the 12th fret on your high e in really any key and your brain will perceive nothing too strange going on. Extending scales beyond single octaves is another way to demonstrate this. In music, context can be very important with your note choices, and providing context in the form of an extended scale can make sense of what you're hearing, or conversely denying context can more or less allow your brain to create it's own sort've context. Once the key change happens, your brain has to re-assess the context, or in this case, lack of context, and re-fill in those notes that aren't there.

Well done. Blazed right through the series. I noticed something similar to the possibly novel effect #1: I always found it increasingly difficult to properly tune sub bass frequencies and would bump them up an octave or two and then back down after tuning. Now I know why. Thank you

About the second to last effect: I beg to differ the reasoning here. From my experience it's not the higher pitch that our head corrects but rather the lower. When I make music with DAWs and I implement bass or subbass, I sometimes don't realize, that the whole bass is a semitone off. Sometimes it's even only one note and I only realize after taking a break from that project for quite some time. Also: Great video series! I've gotta rewatch some stuff tomorrow on loudspeakers. I just finished the series and I had a great time. I'm in love with such phenomenons and even though people praise my hearing, I now just learned how differentially you have to consider each and every one's hearing (is this proper English btw?). I have tried to explain some things to people that they maybe could never have understood and now I know it's because some people hear things other don't, but at the same time I can't understand everything I'm told, 'cause I have a different hearing on my own.

Most of the illusions actually didn't work for me, but often the ones that required open speakers worked well on me through my headset. Your Consonance Calibration Effect is also pretty strong for me, but I'm notorious for my inability to be pitch perfect despite all my years of violin and piano tutoring from elementary to high school. Taking my headphones off and on provided an almost doppler-effect feeling to me, but holding the new pitch when I stop moving the headset.

Thank you for the serie. I found that very fascinating. I have a trained ear and only part if effects did really worked on me, however I never encountered so many psychi-acoustic demonstrations in one place at the time. I confirm that sometimes percieved pitch of a bass sound is shifted towards being in consonance with surrounding tones. And also, without surroundings it’s much harder to determine a key of a melody played with deep bass sound. This effect can be heard on Billy Eilish’s Bad Guy. I also confirm the percepted lowering of pitch in a removed headphones.

The thing about the bass and high sharp notes can be explained with the curve of tone perception.. we get less accurate with lower notes then high ones. So our brain can fake the harmonization in a way that you can tell they're in pitch. I read a study on Murray Schaeffer book telling that we can't distinguish almost 3 semitones in very low frequencies! Also, very good series thanks for sharing :)
@CaseyConnor

Thanks - i agree with the observation that discrimination in low octaves (and with very wide intervals) is more difficult... The focus of that demonstration isn't the difficulty in telling that the two parts are out of tune, it's the "calibration" effect that happens after listening for a bit, and the weird feeling that happens when they are shifted to be in tune.

Very cool series! I just stumbled upon these this morning, and really enjoyed them. Your last illusion brings up one I experience at work (surrounded by industrial equipment). I don't really know how this works but I notice a similar pitch change effect but in the opposite direction with my ear muffs that you do with your head set. When working near a piece of equipment driven by a toothed belt (like the timing belt in a car), this seems to generate a lot of noise with distinctive peeks across the sound band. As I take my ear muffs off, I hear a distinctive up sweep in overall tone from the machine. And as I put my ear muffs back on, I hear an down sweep in overall tone. I'm wondering this may be because the ear muffs filter the higher frequencies better than the lower frequencies?

from a seasoned musician; the sharp high voice was heard as a harmony (without hearing a melody) which I could still imagine after the high voice was lowered. Then, it sounded stronger, as a main melodic theme should. The high voice was weak, but consonant, in spite of its chromatic dissonance. When reduced the half step, it sounded flat, not as a pitch referrence, but as a qualitative difference in the values of the respective melodies. - Auditory illusions have always been a fascination of mine.
