Noise cancellation means, it detects and analyzes the sound pattern of the incoming noise and then generates a mirror “anti-noise” signal to cancel it. The end result is that you hear a very low noise level
Do you like to pause while listening to your favorite band Hit Off? People chatter non-stop when you want to focus on the release of that new song. Be it metro or train, every public transport adds to your frustration with all the unnecessary sounds coming in your ears and disrupting your chain of thoughts.
Let us tell you a story today. Allow us to speak to the insect we all carry within ourselves, a curiosity insect. Do you like to pause while listening to your favorite band Hit Off? People chatter non-stop when you want to focus on the release of that new song. Be it metro or train, every public transport adds to your frustration with all the unnecessary sounds coming in your ears and disrupting your chain of thoughts. So, by now we’ve established, none of us like noise. Just like us, one person found unnecessary noise so frustrating that he actually decided to do something about it.
Now, buckle up your seat belts for this 1978 story!
Yes, you heard it right.
Dr. Amar Bose was on a peaceful flight from Zurich to Boston, but the noise of the plane drowned out the music he was listening to on his headphones. That’s when Bose decided that he would make something that would eliminate the noise and not the music. And that, my friends, was an absolute step in the right direction. Active noise control takes years to fully build itself. In the earlier days, until 1986, this used to be a technology only used by pilots and the military. Soon, noise-canceling headphones dropped their price and became available to the masses too!
With the changing times, a lot of audio wear companies have started manufacturing noise-canceling earphones so that we can have nothing but music.
But how do these noise-canceling headphones work? Wait, there’s a lot on that popcorn while we tell you all about it.
Every sound travels as a wave. Each sound wave is different from the others. Valleys and heights are different for different words. Now imagine saying two words and outputting different sound waves for the same. When we mix the sound waves of these two words we get a phenomenon called constructive interference. Yes! Physics is cool too, wait. Creative interference basically amplifies the sound making the overall combination louder. Have you ever entered a restaurant or crowded place when the crowd was less but as the crowd got bigger, the overall sound also increased? yes right? That is constructive intervention. Now, this is the event the innovators had their eyes on. Like every curious mind reading this blog, they wondered what if instead of making a loud noise, the bus… ceased to exist? He becomes so silent as if he does not exist. This is where all the brilliant minds worked together and came up with the concept of destructive interference. As already mentioned, sound waves have their peaks and valleys. Now noise-canceling headphones have built-in microphones. This noise-canceling mic, when it detects any sound wave from the surroundings (that’s the ooh! part) produces a uniform sound wave of the same wave that is the total opposite! Now there is a peak for every valley, and for every peak? That’s right, a valley. It cancels out the surrounding sounds going into your ears and interrupts your moment with your favorite songs! The waves cancel each other and a flat line flows. It’s the same concept that the Modish Ombre works on, giving you the best possible resolution to the noise around you! It lets you enjoy the modern ombre signature sound without any disturbance, just as it should. But let’s look at one more thing, some types of loud noises usually don’t cancel out in general. Let us know why this happens. When there are sudden and loud sounds around us, for example, a loud thunder or someone calling our name at the top of our voice or even a horning car, the sound waves vary greatly. . , Noise canceling devices make it difficult to detect and modulate the waveform. Hence, these noises enter our ears but the effect is minimal.
Noise cancellation works best for places where there is constant noise. Be it a train, an airplane, a restaurant or a crowded place. ANC technology keeps all these sounds away from your blissful experience!
You see, you can only remove so many sounds at once.
That’s all for today. The show is over, for now, you can unbuckle your seatbelts and get some rest. Here, in a nutshell, you’ve got to know everything you need to know about how noise cancellation works! At Modish Ombre we always want the best for you and believe that you should know what you buy. So, with that, now you know the job
