What Is Active Noise Cancellation?

We all love uninterrupted listening experience. To cancel out the unwanted disruptions, Noise cancellation is the best process.

Active noise cancellation (ANC) is a more advanced noise reduction technique that actively suppresses external noise using specialized hardware and algorithms. ANC technology uses microphones to detect incoming environmental sounds and produces sound waves with the opposite phase to cancel them out. ANC is commonly found in headphones, earbuds, and even some high-end audio systems to provide a more immersive sound game by reducing background noise. Take the scroll down to know ANC technology in detail!

How ANC Works?

ANC uses microphones in the headphones to detect external sounds (ambient noise). The system analyses the soundwaves and generates an anti-noise signal (soundwave of the same amplitude but inverted phase). The noise is eliminated when the incoming sound and the anti-noise signal are mixed together. Real-time processing ensures continuous noise suppression while maintaining the quality of the audio you are listening to. Following such steps, that’s how ANC works.

Advantages of ANC Technology:

There are a number of benefits of ANC. Some of them are as follows:

• Noise isolation: By lowering background noise in loud settings like buses, flights, and crowd, active noise cancellation (ANC) enhances audio clarity and focus.
• Enhanced listening experience: With ANC, you can listen to music at lower volumes, preventing hearing strain and allowing you to enjoy clear audio without needing to crank up the sound.
• Reduced fatigue: ANC helps reduce the cognitive load of filtering out constant background noises, particularly useful for travellers or commuters.
• Improved voice call quality: ANC-enabled headphones can provide clearer voice calls by cancelling out background noise on both sides of the conversation.
  

Other than the above-mentioned pros, the importance of Active Noise Cancellation lies in modern audio devices due to increasing demands for privacy, sound quality, and focus in various environments. 

Best ANC Headphones: Hammer Lifestyle

Hammer offers a collection of high-quality Active noise cancelling headphones. Bash Pro is a top-notch headphone from Hammer that comes with 32 db hybrid ANC and quad mics. These advanced bluetooth offers powerful sound drivers and quick-charge capacity. One can seamlessly enjoy their favourite music, podcasts and videos using these headphones.

ANC vs Passive Noise Cancellation

By producing inverse soundwaves, active noise cancellation uses electronic components to cancel out background noise. It is ideal for reducing low-frequency noises like engine sounds or chatter. Conversely, passive noise cancellation (PNC) depends on the actual physical construction of the headphones to filter out noise. This can include padded earcups that form a seal around the ear, but it is less effective at reducing lower-frequency sounds compared to ANC.

Noise Reduction Techniques

There are two main categories of noise reduction:

• Feedforward ANC: Microphones placed outside the earcup detect noise and generate an anti-noise signal before it enters the ear.
• Feedback ANC: A microphone inside the earcup picks up residual noise that passes through and adjusts the anti-noise signal accordingly.
