How Active Noise-Cancelling Works

Active noise cancellation minimizes external sounds by using advanced technology. Here's how it works:

Microphones and Sound Waves

Active noise cancelling technology relies on tiny microphones placed on the outer housing of the headphones. These microphones constantly listen to the environmental noise around you. Once detected, the headphones quickly generate an artificial sonic mirror image of that external sound. This process involves creating sound waves that are the exact opposite of the unwanted noise, a technique known as antiphase. When these opposing sound waves meet, they cancel each other out, resulting in a significant reduction of ambient noise. This clever use of sound waves ensures that you experience a quieter environment, allowing you to focus on your calls or music.

Phase Inversion

Phase inversion is a critical component of active noise cancelling. By producing sound waves that are 180 degrees out of phase with the ambient noise, the headphones effectively neutralize the unwanted sounds. This process is instantaneous, ensuring that you enjoy continuous noise reduction without any noticeable delay. The result is a more immersive audio experience, free from the distractions of external noise.

How Passive Noise-Cancelling Works

Passive noise cancelling headphones take a different approach to noise reduction. They rely on physical design and materials to block out sound.

Physical Barriers

The primary mechanism of passive noise cancelling involves creating physical barriers that prevent sound waves from reaching your ears. Over-ear headphones with thick, padded ear cups form a tight seal around your ears. This seal acts as a barrier, blocking out a significant amount of external noise. Similarly, in-ear headphones fit snugly in your ear canal, providing another layer of protection against unwanted sounds. This method doesn't require any electronic components, making it a straightforward and often more affordable option.

Material Design
