How Does Noise Canceling Work - Learn Everything in Here

Part 1. What Does Noise Canceling Mean

Noise Cancelation means to reduce, minimize, or eliminate noises in the background by creating a specific sound effect that affects the listener's ears by diluting the external noises. Some loud and high frequencies remain audible but not in their original state, which means you can hear that it has been reduced thru this feature. In a nutshell, the basic principle of it is to reduce the noise of sound waves before it comes to the point it reaches your ears.

Furthermore, it has become a popular feature for most headphones and earphones so that the listener can enjoy the music or audio track without distracting sounds in the surround. Plus, some microphones took a big step and adapted this feature. While recording thru the mic, when this is activated, low and some mid-frequency sounds will not be part of it.

But now, you can even find a headset with a microphone with a built-in background sound cancelation. The idea became popular not only for the audiophile but also for the music enjoyer of this modern era. With the addition of an enhancer, you can even improve audio quality to its finest.

Part 2. What is Active Noise Cancellation

What is Active Noise Cancellation? In the short term, ANC is a chipset inverting the sound waves by neutralizing them back to zero. For example, if the sound outside is -3, it will now match that by making a +3 inside your device. Truly, this function benefits everyone who wants to enjoy recording and listening to music. However, the biggest issue is that it needs to be perfectly lined up with the noise presence to be accurate enough to reduce the signals or even lose it before it reaches your ear. Though you can set it up or wear it properly, it won't cancel all of the mixed signals; it gets perfect, but it can still reduce the noise up to 25-45dB of sounds.

Not everyone might know that three classifications of ANC are built on headsets. If you are wondering what these are, you can read the additional information we have added below, and we will make it simple for you to understand.

Feedforward Active Noise Cancelling:

• Also known as Mic Outside the Ear Cup.
• Feedforward ANC is the straightforward type that is available on a headset.
• It uses a digital signal processor or DSP to detect the noise signal via a built-in mic.
• Reduce high-frequency noises up to 1-3 kHz depending on how quickly it responds.
• The mic is sensitive and can even amplify the noise from another angle.

Feedback Active Noise Cancelling:

• Also known as Mic Inside the Ear Cup
• It is adaptable to different variations, especially to the listener's perspective.
• It has a self-correcting mechanism even if the wearer uses it oddly.
• Perfect choice for canceling low frequencies with longer wavelengths than usual.
• Low-quality Feedback ANC can result in a high-pitched shrill closer to the ear.
• It can even filter the sound from the speaker on your headset, like bass.

Hybrid Active Noise Cancelling:

• It combines two known as Mics Outside and Inside the Ear Cup.
• It has a two-way noise cancellation process for a better background canceling function.
• Suppressing the noise up to the extent of different frequencies and adaptive situations.
• However, the price of it is twice or more than the previous one.
• It can even produce white noises as a counterpart of it.

Part 3. How Does Noise Canceling Work

How does noise canceling work? For starters, how it works may seem undefined, but the real answer is that it doesn't. Generally speaking, before the sound waves reach your ears, there are three ways it works since there are three types. Here we will introduce how it works so you will have a clear vision.

First, Feedforward Active Noise Cancellation will use your headset's or earphones' built-in microphone. Once the wavelength and signal reach that external mic, it matches the background signal by creating an anti-noise signal before it reaches your ears.

Next, the Feedback Active Noise Cancellation may seem similar to the first one, but it doesn't really. After you wear this type of headset or earphones and start using it, it will send everything the built-in microphone catches up inside the headset back to the speaker. You can even hear the noise cancellation effect better than the first one.

Lastly, the Hybrid Active Noise Cancellation. With it, the first noise signal will pass through the external microphone to the speaker. But before it reaches your ear, it will undergo another cancellation process with the built-in microphone inside the speaker. When the noise is already removed, it will now go to the speaker, and you will be able to listen to music with less low-frequency music.
