The Rise of Active Noise Cancellation

Active noise cancellation (ANC) emerged as a game-changer in the world of headphone technology. Unlike passive noise cancellation, ANC employs microphones and advanced signal processing algorithms to actively combat external noise.

How Active Noise Cancellation Works:

ANC headphones continuously monitor the surrounding environment using builtin microphones. These microphones capture incoming sound waves and send them to a digital signal processor (DSP), which analyzes the sound pattern and generates an "anti-noise" signal.

This anti-noise signal is then fed into the headphone speakers, effectively canceling out the external noise by producing an inverse sound wave.

Benefits of Active Noise Cancellation:

Active noise cancellation offers several advantages over its passive counterpart. It excels at reducing low-frequency sounds like engine noise, traffic, or the constant drone of an air conditioner.

By actively countering incoming noise, ANC headphones provide a more immersive and uninterrupted audio experience. They allow users to enjoy their favorite music or engage in important phone calls without distractions, regardless of the noise environment.

Some high-end ANC headphones also feature adjustable noise cancellation levels, giving users control over the amount of ambient sound they want to block.
