Amazon Patents Noise-Canceling Headphones That Could Automatically Turn Off When It Detects Certain Sound Patterns (thenextweb.com) 82

An anonymous reader shares a report via The Next Web: Noise-canceling headphones are great for tuning out the din around you when you just want to focus on listening to music or enjoy some peace and quiet. Unfortunately, they also mute sounds that you might need to hear -- like someone calling your name. Amazon has a pretty cool idea for solving that problem. It was recently granted a patent for headphones that not only cancel out noise, but also listen to specific sounds or phrases (like 'Hey Ben') and respond by automatically turning off the feature so the user can hear sound from their surroundings. That should make it safer for use in noisy environments where you might actually need to pay attention to the occasional alert, such as a construction site or an industrial facility. In addition, the headphones can also listen for phrases to turn noise canceling back on again, so the user can resume their listening experience hands-free.

    If there is so much noise around you that you need noise cancelling headphones, how are they going to accurately detect these sound patterns?

    As an example, my GPS has voice controls. Very handy, except if the radio is playing at even the faintest volume levels the GPS simply can't recognize the activating words 'voice control'. Hell, even with the radio off I sit there like a fool repeating 'Voice control. Voice. Control. Voicecontrol. VOICE CONTROL DAMMIT!' to get it to work.

    This seems more like a gimmick than a truly useful piece of hardware.

      Fast Fourier transform, dominant-frequency analysis, and so forth.

      Imagine detecting sounds approaching, human voice, and other such things, and filtering them in or out. The sound of approaching vehicles gets let through.

        Recognizing sounds and phrases isn't new. Executing a control action based on that input is not new. Noise cancellation is not new. If it were me I'd laugh loudly when rejecting this patent.

        Now, if you could just allow that phrase only to pass through in real time, or even with some delay, that would be quite a technology to patent.

          It it doesn't tell you why it deactivated the noise cancelling feature, then you are left with guessing why.

            I should note that I entirely agree with the 'should not be patentable'.
            This is a very simple concept that is not worthy of protection. Specific novel implementations of it in principle may be.

      This is a patent. The patent probably just includes a small black box labelled "ambient noise analyzer" in what is otherwise just a standard set of headphones. The related text explains that (not how, never how) the "ambient noise analyzer" will monitor noise and listen for command phrases to enable additional functionality.

      Now that this is patented, R&D has 20 years to make it work and sell enough to make profit.

      • How does R&D even enter into this? They can now simply wait until someone else uses this, then send a lawyer to their office to wave that patent in their face.

      Oh, it hears you. It's just passive-aggressively ignoring you. I can imagine its internal computer voice quietly muttering to itself, "You're not the boss of me." or screaming into the electronic abyss, (as Cheryl [wikipedia.org] from Archer [wikipedia.org] "You're not my supervisor!"

    • For decades they sold hearing aids that removed the background noise and focused on the directed noise. The human voice has a set of harmonics that is rather common across people. As well if it is at a particular amplitude you can say this voice is talking to you vs. standard background noise.

      • From someone who has no clue, this seems like a novel idea.
        However, it is entirely clear to anyone in the field that you can put together things that will work much better than simple voice activation.
        For example - picking up 'Hey John' - while looking at you (assuming your name is John) makes it pretty certain someone wants to talk to you, and is not merely talking to their friend next to you.

      It doesn't matter "how". Amazon is not going to produce such headphones or even design them. But when Sennheiser or Bose will, then Amazon will demand their share of profit.

  • I feel like it'd be a better idea to put this in the devices that are actually playing the audio. Rather than put it in a pair of headphones, build it in as part of Android, iOS, Tizen, FireOS, and whatever else the devices are running these days. That way we can have this awesome safety feature with ANY headphones.

    • Unless you carry your phone/device externally, the frequencies it pickups will be slightly different.

      Because sound and noise is very complex and to cancel it they are a lot of tight variables that needs to be considered. A fraction of an inch could amplify the sound vs cancel it.

      The noise cancelling effect needs to be in the headphones as you need very accurate specs for the headphone drivers, the background noise microphones and the exact distances between them.
      Listening to background noise and disabling the noise cancelling could be done by a phone, but then you need a standard protocol for controlling the headphones, and the feature only works when you're using the phone. A lot of people with noise cancelling headphones will make use of them without any audio source attached, as

    IANA.. anything relevant here. I work in construction management (many years prior in IT, security, etc, hence me being here), and often at my desk on the jobsite the grinding, hammering, cutting, you name it gives piercing noise that makes it f'ing near impossible to concentrate. So I've been eager to use noise cancelling.. however there are issues.

    The obvious one, pointed out, is possible cancellation of noise you really need to hear instead of ignore, like something collapsing, someone calling you, etc. (especially when walking the site instead of at the desk) In a construction environment, it'd be very hard to programmatically distinguish the good loud noise versus bad loud noise- scaffolding may be collapsing, or it may just be a steel worker cutting an extra toe angle off of a joist that was manufactured incorrectly and that falling to floor. It's probably kind of like if an active shooter scenario happened at a gun range- which gun shot is bad? You can perhaps tell by direction sound was aimed in that case, but standard folks listening will mostly just hear shots until they notice something amiss. (I pray I never experience that.) I suspect the best answer in industrial application would be "partial cancellation," a bit more noise let through than Bose currently lets through, kill plainly regular noises like compressors but let irregular noises like crashes or hammering through.

    However, my sister is an audiologist and pointed out something else- there really hasn't been a study of noise cancellation in loud environments, and it's benefit to ear health. While the cancellation is creating opposing waves and all, there's no study on the actual sound pressure that gets to the ear drum and possible effects of that, even if it is in an inaudible range. I can say when sitting at my desk and I turn on cancellation with my Bose QC20i's, it does WONDERS for noises like compressors and such- but I can tell there's a pressure in my ear from the cancellation. So there's still a valid health concern to be investigated before they'd be OSHA approved for use- I'd rather not lose my hearing thinking the cancellation was a good noise reducer when it had negligible health effects. As such, right now OSHA doesn't really approve noise cancellation in any construction environment, just standard NRR rated blocking materials.

      I have a set of high-end Bose noise-cancelling headphones that I use occasionally.

      They're made for airplane pilots, so they to cancel loud noises and noise in certain frequency ranges, but don't cancel the ranges of human speech. Talking while driving is pretty clear - the phones cancel out all the engine and road noise. (Which makes them less useful to me, because I wanted them to cancel *all* noise in the environment - to get some sleep at Burning Man.)

      I don't know about construction specifically, but you can still hear all ambient noise through the phones - it's just attenuated.

      Not that you should use these in construction, but the cancellation is not that bad or complete.

      • I bought a pair of of consumer Bose noise cancelling ones in hopes of getting some quiet time from all my colleagues to work. But they are very poor at blocking voices. Computer cooling, AC, airplane noises when traveling works. But sadly I don't have to remove them to hear what people are saying.

        I am guessing that the electronics can't work fast enough to produce a counter noise that aren't some sort of static noise.

      With all due respect to your sister, active noise cancellation generates out of phase acoustic waves of equal amplitude to the incoming wave, and acoustically, the waves cancel out in the air, before they hit your ear drum. There is no energy left to hit your ear drum, and accordingly, no possible hearing damage (provided the phase is correct, which it is, because even with some temporal slop, they reduce most of the energy. Otherwise, they'd be amplifiers, and you'd know it right away).

      Interesting that OSHA does not approve noise canceling headphones but they do approve "reactive ear protection" which is the same thing without any music throughput.
          I use a reactive headset attached to a hard hat. I love the fact that mid range vocal frequencies are passed through with other frequencies cancelled out.

    You'd think it would be a better idea to work in the opposite way like a welder's auto-darkening facemask works. It should let all sound through till it detects high dB levels or a certain level of white-ish noise and then instantly start cancelling and then disabling the cancelling feature when the noise or loud sounds stop.

      You can get a decent pair of them for $30 or so. I have a pair that I wear at the shooting range. They are outstanding. The only downside is that if it's a windy day it can get pretty annoying with the wind noise in your ears. (more expensive pairs probably have solved this, but I'm cheap.)

      Those have been on the market since the 1970s as "reactive hearing protection". The price is down from $300.00 for high end shooter's muffs in the 70s to the $9.95 reactive ear plugs I bought last year.

  • This could change everything, if it simply filled in its own content instead of unmuting. Agreement with my bizarre political opinions would be universal, that cab {buy Crest} driver would be yelling compliments concerning my driving (and parentage), and the homeless people yelling at their imaginary friends would {buy Crest now!} be shouting the current news and {buy Crest immediately!} weather. Hard to see the harm in that ...

  • But I don't see the benefit over a simple button.

  • I've tried expensive noise cancelling headphones and found them pretty useless. They didn't filter out things like conversations at all, just made them tinny-sounding. Still just as distracting. What I find does work is IEMs with triple flange earpieces. They effectively become earplugs with headphones in them. My $50 headphones with those are massively better than the $300+ "noise cancelling" ones I tried.

    • IEM or some good old fashion closed-back headphones seem to block out unwanted sound for me better than most noise cancelling headphones. Getting IEMs that fit well can take a little trial and error to find, especially for people who have a narrower entryway to their ear canal. For people with an average sized ear canal, the PU foam plugs work very well and are more comfortable for me than the triple flange (really just personal preference). I got the PU foam ones as an aftermarket option, and stuck them on

      You are asking the tech to do things it is not designed for. Noise cancelling headphones were never designed to filter out intermittent sounds like a conversation. Try wearing them on an airplane flight to cut out the engine noise. Or, wear them while using a power tool so you can hear your music over the noise of grinding, etc. They work great for cutting out constant droning background noise. BTW, the Sony Fontopia line has better specs and performance at a low middle price range than the expensive

  • Noise cancelling headphones already are pretty terrible at eliminating sound from conversations (they're best at eliminating sounds from nearly-constant sources, such as from an HVAC or an airplane engine).
