    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.

      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.

    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 :)

      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).

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?
      I might just be misunderstanding physics here. When I tried asking ChatGPT, it stated that your ears receive twice the amount of energy, but due to the cancellation effect, the overall volume used is lower so making ANC useful.

    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.

    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
