Conceptually speaking, the noise canceling earphone refers to a kind of earphone that uses some method to reduce noise. The current mainstream is the active noise canceling earphone.

The reverse sound wave, which neutralizes the noise, to achieve the noise reduction effect of the headphones. Nowadays, more and more consumers are buying noise-reducing headphones or wanting to buy them. But how do noise-reducing headphones work in our lives? What are the limitations?

So what are the application scenarios for noise canceling headphones in life? Come, let us give you a few examples. The first is the development of transportation during the journey, which brings more choices to people's travel modes. Aircraft, trains and cars are chosen. However, this kind of transportation is accompanied by noise. The long-distance travel of ancient countries, the noise of vehicles is indeed a very disturbing factor.
The noise generated by these vehicles is very large, and it is always around the ear during the journey. At this time, it is time for the noise-reducing earphones to show their talents. The frequency of the noise emitted by the vehicle is low. It is just the noise-reducing earphone that is best at reducing the noise. The noise-reducing earphones can show the noise reduction effect and put on the headphones. After turning on the noise reduction, it is obvious that it is quiet.

The high-frequency sounds such as voices and ring tones are not completely isolated. It's obviously a lot smaller, and it doesn't make you hear that your boss is calling you.

First of all, the noise canceling headphones can not isolate all the noise, and the noise isolation is somewhat important. The isolation of low frequency noise is more effective, but the high frequency noise is relatively less obvious.
