The Bose guy's frankness and clarity are exceptional, as well as the lady who worked at Dolby who speaks with such clear insight and an almost poetic structure in her arguments. These videos live and breath through a good choice of interview subjects and you nailed it here.
Human Intelligence truly knows no bounds. It's amazing, almost surreal that a simple desire, an annoyance, or a simple business thought can spur forth such intriguing technology.
Depends on where you are, here in Brazil I paid 2k (415 dollars) for my Airpods Pro first gen, back in 2020. Curiosity: In Brazil the Iphone 14 1tb costs 3219 dollars (june 2023).
This was really interesting, As someone who wears hearing aids. I find the idea of noise cancellation absolutely amazing, I’m in awe of the technology that we have these days!
I so wish hearing aid manufacturers paid more attention to the extreme need for ambient noise reduction! Not that the top brands don't try...but this feature could be so much better and could make life more enjoyable for many people.
Such a fascinating video. I can’t wait until the successor to the Bose 700 comes out (hopefully sometime this year - surprised there have been no leaks at all)
So THATs that the AirPods pro starting noise is for, and AirPods transparency mode is unbelievable, I still have no idea how two drivers in my ear can recreate direction in a real world. I can pinpoint where I hear sounds from and it pretty much sounds like I don’t have anything on at all.
As a person who makes music I've come the the conclusion that music, noise and sound is magic. I also believe removing these waves is magic.... In summary, sound is magic so appreciate it. Side note, use some type of ear protection. You can only lose the hearing you have, so protect it!
Thought this is really well done and gave a really good explanation of how the technology works in a level that most people can understand what I do take issue with in this video though is that noise canceling technology of this type actually goes back to the 1960s with analog processing as opposed to more recently with both using digital signal processors.
Love the behind the scenes look at the technology. The only error made was that you're saying "AirPods Pro" but showing the AirPods 3rd generation. Woh-wah.
I have the Pro 2 and I rarely used ANC because it feels too clogged in my ears. Like the silence is caving in, it’s suffocating… It’s suitable perhaps on noisy environment but if you work from home and all quiet, I’m more inclined to use the Transparency mode 😅
This technology fascinates me after I have learnt about it in my highschool physics class. Beforehand, I used to wonder how do the pilots listen in such noisy environments
It's a great technology but at the same time you really need to be aware of your environment. I have a crazy beat studio buds it's crazy at canceling noises but i still got an airpod pro because i need to be aware of my environment It's crazy dangerous these days and you need to be sharp and at alert.
I use my Galaxy Buds+ to mow the lawn. I can listen to music, and it deadens the noise of my mower and other equipment. Would be nice if it could completely block the sound, but the fact that sound travels through my body too means that active cancellation would have to account for the stuff that gets to my eardrums via my soft tissues and bones as well as my ear canal. That seems like it would need to be calibrated to each person, in each unique situation.
Because of construction noise I've been using Apple's Max since they came out. After a few hours my inner ears hurt. I imagine it's because ANC cancels sound but produces (increased) pressure. Is that so, or am I also imagining the pain? :-)
@@kurumitokisaki4844 That's the ideal case. In reality, I don't think ANC does perfect destructive interference, like the lady from Dolby mentioned - if the sound is not constant, the ANC can't do too much to those frequencies.
What I can not understand yet about active noise cancellation if also protect the people from louder environments. An example: if I work work near an industrial machine that requires earbuds for preserving my hearing, will the use of noise cancellation only reduce the noise I perceive or also effectively preserving hearloss? I never found articles about this.
for those of you looking to buy an anc headset after watching this video, its best to do your own research and buying what feels best for you. if youre looking for earbuds with only the best anc and nothing else, the best you can get with todays money is the Bose QCII, and the best budget friendly ones are the Soundcore A40s. They are not only objectively the best, but also scientifically, in terms of decibels of sound reduced. However, theres definitely more you should look for in headsets, specifically audio quality, comfort and fit, mic quality, battery life, etc. Those saying the Sony is superior in anc technology are simply wrong. Bose has far more experience and expertise in it. But Sony does make better all rounded earphones :)
I use Jabra wireless EarBuds and Sony Wireless HeadPhones. EarBuds all the time when out to hear notifications and health anouncements as I walk miles... Also on Subway rides and Bus too with one's really loud like at home..
@CannabisCultureTechLife I think he is talking about decibels and my guess would be no apart for the device blocking some off the sound the ANC will not help you with sound that is to loud.
no active noise cancellation is able to cancel out every single outside noise. for that, you need actual earplugs or IEMs (in ear monitors) with really good sealing and correct tips for your ears (fit and sealing are very personal. an IEM that fits and seals perfectly for me might not do the same for you). If you're really serious about this, you might wanna look into custom IEMs: they make a mold of your ears and create an IEM perfect for you (but they can get really expensive).
Probably the same way as Bose, a mix of a dataset and super optimised algorithm, so the earphones can adjust accordingly. The algorithm probably checks for stuff that fall in the category of "loud noise - drill; cars on highway - people in dense city" etc, and adjusts when there is a sharp change (someone calling your name up close, you speaking/singing).
It still seems odd to me why ANC technology has been forced via earbuds rather than neckbands and earphones where there is plenty of room to experiment and achieve more.
I have a specific question. He said that the brain interpretes the sound as 0 but is the sound still there and the ear drum is still vibrating even though the sound is canceled?
I have never wore Active Noise Cancellation earbuds or headphones. Is it really worth it? You really never hear background noise like in a road or in a noisy market?
yes, it is crazy. I remember the first time i used one. It was an airpods pro of my friend, which has one of the best anc in the market. I legitimately felt like isolated from my surroundings. It was like your eyes telling you you are in a crowded place yet your ears tell you youre in your room in the middle of the night.
Gravity travels at the speed of light. So, it’s instantaneous. That is, sound travels at a measurable rate from the headphone speaker to the ear canal. Any inverse function requires a calculation. Because gravity travels at the speed of light, this likely wouldn’t be possible.
Gravity is a wave. This can be proven in many ways: in the atmosphere or through a moving object. The point: gravity produces ripples that have amplitudes and this is used to calculate its speed.
I've always been disappointed by noise "cancelling" headphones (I've had three over the recent time) - that term is hugely misleading. They should rather be called nose reduction headphones, that would be more honest.
I'm no expert and pardon my ignorance but do they have to predict sounds to cancel them. The headphones technically knows what is playing, cant they just try to eliminate every other frequency that is not inside whats playing? Doesn't this solve the prediction problem? I would love to hear from someone who knows this stuff
So is this worse or better for your ears? You can’t HEAR the sounds but you’re exposing your ears now to twice the amount of energy that it would’ve otherwise received, right? That’s the part I never understood and nobody touches on. How can your ear receive twice as much info without experiencing more physical wear?
@@InternetDisplayofPower Where does the energy go? To my understanding, there is energy (sound) coming from outside and also energy (sound) coming from the headphone. So how does 2x energy not get transferred into the ear? I get that they 'cancel' each other out so we cannot hear it, but what happens to that energy?
@@scpdatabase969 think of it like gravity. if you have an object in your hand, it is being pulled down by gravity with a certain force F. Your hand pulls it up with the exact same force F in the exact opposite direction. The resulting force the object statically "receives" is exactly zero (assuming we can ignore torque and whatever not). However, (in some sense of 'system') the total power delivered in this system is definitely not zero.
@@simondonne7865 In this example, isn't the hand exerting force equal to the force of gravity so that the apple is standing still? It still experiences the force from the gravity and the force from the hand. They are simply static. In my mind, the example is more like the apple is on a surface and there are 2 forces pressing on its sides to hold it still. When one side presses harder, so does the other side. This way, the apple is static. However, there is increasing force applied to the apple to keep it static, so eventually, when there is enough force, damage occurs, even though the apple remains in the same position. Replace apples with your ears and that is my question. If the noise is SUPER LOUD, enough to damage your ears, and you have ANC that can stop the noise, would your ears still be damaged from hearing both sounds at the same time?

Yes, it does protect ears from loud noises, but the high-end ones from Bose and Sony are great options for that
no, because the driver is too small to counter heavy loud noise
So could they potentially make a noise cancelling speaker? Have two speakers that also play the inverse of the sounds sounds around you 🤔
I need a set of ear buds that eliminates leaf blowers sounds, which, in Southern California are ubiquitous and continuous. Annoying.
They do struggle with those
I have spent a fortune on different models but none can bring me silence from noisy neighbours 😢

Can you generate an inverted gravity wave and cancel gravity?
