Whether you're on a plane, subway, or a crowded street, noise-canceling earphones will drown out almost everything around you. Bringing peace and quiet to your ears. But do you know what is ANC and how do the earphones work?
ANC helps you to focus on your work. It's a function that can work without playing music. As we explained above, the earphones create a sound wave to cancel the ambient sound. You can active your earphones' noise cancellation function when you need to focus. For everyday situations, it is important when you want to concentrate on yourself.
To some degree, ANC earphones protect your hearing. Loud music damages your ears, with the ANC function, users do not have to turn the sound too loud to hear.
ANC technology is usually built directly into the earbuds, a microphone picks up the ambient noise and transmits it to the ANC processor. An identical 180-degree inverted waveform will be generated and sent back to the headphone speaker. The ambient noise wave and the newly generated waveform cancel each other out. This wave acts like a noise eraser and it cancels out the surrounding noise without diminishing the audio that you want to hear.
ANC filters are designed to operate mainly at the low frequencies you won't miss the important acoustic signals like an ambulance passing by. With ENACFIRE A9, it is easier to hear the waitress's voice in a crowded coffee shop. ENACFIRE A9
ENACFIRE A9 also has a transparency mode which allows you to hear your surroundings better than you can with noise cancellation off. To activate the ambient mode, tap the left earbud once after noise cancellation has been turned off, and the voice will confirm 'Ambient on'.
To turn off transparency mode and return to active noise cancellation, tap the left earbud again. The voice will confirm 'Noise-canceling on'. We will talk about Transparent mode in the next article.
