Noise cancellation in phones

Noise

Our phone has more than one microphone. In most cases there will be a secondary or tertiary microphone that is placed in strategic points around your handset. One company making strides in noise reduction is Qualcomm. The company's influence in technology is built into a number of its chips. These chips are the same ones that are found within any number of the highest end noise canceling headphones. If you hate the noise that millenials check out the noise cancelling phones available in the market now.

So how does this not cancel the music your listening to? In other words, how does the frequency it produces not affect the music your listening to??

@rdixon5k I knew before how they work, but it is still hard for me to believe that it actually works..

@jmoore5j Interference is irrelevant here because if you try to rely on interference it will work only in one single point is space.

@dcox5s Destructive Interference sounds like a dangerous thing to talk about on an airplane.

The first time I put on noise cancelling phones I was completely staggered by the experience! So cool to know how it works.?

But the real question is: What does that noise-cancelling sound actually sound like??

@jrodriguez6c NO! It's demon magic!?

@jrodriguez6c oh, thanks for the anwser?

@jrodriguez6c it's white noise. you can hear it, but it's not very loud, and generally more pleasant than any outside noise. It's only designed to work a few inches from your ear anyways.?

  • Reply

@jrodriguez6c it layers a higher pitched frequency over other noises to cancel sounds, which is why it works best with low droning noises and not completely for things like the high pitched whines of a toddler.?

There are two kinds of noise-cancellation and this does one, exterior sounds

@cporter6k not active cancellation in most cases. the fancy electronic ones are still passive

  • Reply

@cporter6k Passive noise cancellation would just be muffling, nowhere near as effective.?

  • Reply

@rgonzalez6m I don't get it. I thought waves simply pass through each other and are destructive only at very select points where their frequencies match up just right

@rgonzalez6m Bring them in for their first flight when they are old enough to be excited about it and know how to chew gum.?

@mcarpenter6o I hate it
