    Noise cancellation is something that I didn't think I'd love, but I do. Sometimes just to keep out ambient noise and isolate myself when working and sometimes when in a bus or on a train... well... it's ab-solutely a game changer.

    I love my Bose QC35s for both the active noise cancellation when I'm flying, and also using them wired (and passive) when I track and sequence in the studio. I've been using them for so long that I've gotten used to the freq response of both modes. Great video!

    This is great knowledge. Thank you Kyle.
    I use ATH50x for producing, DT880 pro for mixing and 1000XM4 for casual listening music.

    hello, I have a question to you: For conservation of energy law, the acoustic energy of the original sound wave must to be converted (maybe disspated) by some mechanism during the addition with the second out-of-phase wave. In mathematics we already know that the sumation of 2 waves (one inverted by 180 degrees) leads to cancelation., Nevertheless, in real nature, the energy is converted by some physics mecanism. Then the question is, which is that mecanism or where is the original energy afther all procedure?

      This is a great question, Dynamic Audio! I’m actually not sure how to properly answer. There is a discussion here that you may find helpful: physics.stackexchange.com/questions/23930/what-happens-to-the-energy-when-waves-perfectly-cancel-each-other
      Hope this helps!

      Very interesting question. My guess is heat (within the electronic circuit that has to put energy into the cancelation process), as is often the case.

    • @riimaamusaa1211
      @riimaamusaa1211 2 ปีที่แล้ว

      Could it be a combination of energy releasing as sounds, heat and some how kinetically?

    • @rebluecrow
      @rebluecrow 2 ปีที่แล้ว +3

      Sound is a wave of air pressure. When you produce a new sound that is the exactly oposite wave you’re physically pushing when it was pulled and viceversa. It’s kind of the tug of war, you have to put a force (energy) to impede movement.

      The noise canceling in these Sony headphones is phenomenal! If you want noise cancellation, I’d go with those. If not, that’s a much bigger conversation that needs its own video!

    I've had good experiences with Koss headphones.
    Idéale and specially SilverCrest have proven to be the best on my opinion. If You want headphones, where price meets the quality. Bang for the buck. Hope they're available in the Us.

    Interesting! Can you do a frequency sweep and generate a reponse graph for the active noise canceling headphones? From what I can tell, Sony, B&W, and Bose are all releasing updated models, so a comparative graph would be great.

    Good video. Yes, I have the Sennhieser HD 4.50 BTNC’s and have replaced the plastic ear pads with valour and added cushions to the headband, so they are quite comfortable now. Like you, I prefer a closed back headphone for Tracking. I use Sennheiser HD 280 Pros 64 Ω and Beyerdynamic DT770 Studios 80 Ω (same as Pro models).

    I have a pair of EX-29s... My go-to headphone unless I have to use bluetooth. I initially got them because I have VERY large ears... not quite big enough to fly (sadly). The Direct Sound headphones have the largest earcups I've found. In fact, that leads me to a question... can you confirm that the ear dummy has a large enough flat surface to get a full seal? That noise comparison did not seem to be as effective as my personal (uninstrumented) experience.

    Does active noise cancellation protect your ears against loud noises?

    • @AudioUniversity
      @AudioUniversity  2 ปีที่แล้ว

      In theory, yes. But for very loud sounds, it’s far better to use earplugs.

    I do not use noise-cancelling headphones at all, but can always use some recommendations of good headphones to use for music production. I always wondered how those NC headphones worked so that was interesting.

    What is the difference between passive and active cancellation (from a physics/engineering perspective, not just what was explained here)?

    • @AudioUniversity
      @AudioUniversity  2 ปีที่แล้ว +1

      Passive isolation utilizes absorption and acoustic separation instead of electronics.

    step aside dummies...lets get actual with this...lets break it down,...Noise/Cancelling/Headfones...ok so u wouldnt put a speaker in headfones to cancel noise...bcaz spkrs make noise... this is advertised as the 8K screen that ur watching on ur 4k screen so how do u no what 8k looks like??? but u rush out n buy 1 bcaz at the shop u wont see the 8k next to the 4k to compare both...its called marketing...the idea of noise cancelling headfones is total BS....the spkr fitted is the closest source of sound to your ear..so everything else is minor as a comparison...the more u turn up the volume, the less u can hear everything else...pretty straight forward really..
