ANC vs ENC Earbuds - All you need to know

While using my earbuds on a busy street, I realized how well they blocked out the noise around me. Curious, I looked into the technology behind it and found out about noise cancellation. So, you know it hasn’t been long since I have known about it. 

Today I am going to share with you what I learned about earbuds. Let's explore how these features work, their benefits, and which one might be right for you.

 What is Noise Cancellation?

It is quite clear from the word itself, noise cancellation- a feature that cancels the noise. In more technical terms, it is a technology designed to reduce unwanted ambient sounds, providing a more immersive and distraction-free audio experience. It works on the principle of sound wave interference, where opposing sound waves can cancel each other out.

There are two main types of noise cancellation: passive and active. Passive noise cancellation relies on physical barriers like ear cushions or in-ear seals to block out external sounds. Active noise cancellation (ANC) uses advanced electronics to counteract ambient noise.

The effectiveness of noise cancellation varies depending on the type and frequency of the noise. It works best with constant, low-frequency sounds like aeroplane engines, air conditioners, or traffic noise. Higher frequency sounds and irregular noises are more challenging to cancel.

Noise Cancellation in Earbuds

Noise cancellation is a crucial feature in modern earbuds, significantly enhancing the audio experience by reducing unwelcome atmosphere sounds.

So, you see it was this particular feature in my earbuds that was blocking all the noise. This technology, which includes both Active Noise Cancellation (ANC) and Environmental Noise Cancellation (ENC), caters to different needs, making it essential for various users. In this blog, we will discuss the types of noise-cancellation features in earbuds.

 ANC (Active Noise Cancellation) Earbuds:

So, what exactly are Active Noise Cancellation (ANC) earbuds? They’re a huge leap forward in personal audio technology. Here’s how they work:

• External microphones: Tiny mics on the earbuds constantly listen to the surrounding noise.
• Digital signal processor (DSP): The captured noise is sent to the DSP, which analyzes the sound waves in real-time.
• Anti-noise signal: The DSP then creates a mirror image of the noise, known as an "anti-noise" signal, which is the exact opposite of the original sound.
• Noise cancellation: This anti-noise signal is played through the earbuds' speakers along with your music, cancelling out the ambient noise before it reaches your ears.

From my experience, ANC earbuds are a game-changer, especially in noisy environments. It is a very useful feature if your colleagues are loud like mine, hahaha kidding! They effectively block out low-frequency sounds like aeroplane engines and air conditioning units, making them perfect for travel.

However, they are less effective for sudden, high-frequency noises like people talking. Many modern ANC earbuds offer adjustable noise cancellation settings, allowing you to customize the level based on your surroundings. Some even include a transparency mode that lets in external sounds, which is great for safety when walking around busy streets. Overall, ANC earbuds have transformed my listening experience, making it much more immersive and enjoyable.

 ENC (Environmental Noise Cancellation) Earbuds:

Like ANC, there's another type of noise-cancelling technology called Environmental Noise Cancellation (ENC). While ANC focuses on reducing ambient noise for a better listening experience, ENC is designed to improve the clarity of outgoing audio during voice calls or recordings. ENC earbuds use multiple microphones to capture both the user's voice and surrounding noise. Advanced audio processing algorithms then analyze these signals in real-time to distinguish the user's voice from background noise.

Here's how it works:

• Microphone array: ENC earbuds have strategically placed microphones to capture environmental noise and the user's voice.
• Audio processing: Sophisticated algorithms analyze the incoming audio, isolating the user's voice from the background noise through techniques like frequency analysis and directional audio capture.
• Dynamic noise reduction: The system minimizes background sounds by suppressing certain frequencies and amplifying those most associated with human speech.

I mostly prefer ENC inside the office environment where I must attend virtual meetings, or while making a call or hearing a voice message.

The best part about these earbuds is that some high-end ENC earbuds even use artificial intelligence to improve their noise cancellation based on usage patterns.

While ENC primarily focuses on outgoing audio, many ENC earbuds also enhance incoming audio during calls, ensuring a clear two-way communication experience. However, ENC is not typically designed to improve the overall listening experience for music or other audio content in the way that ANC does. But that doesn’t make it less good, or it might as well. You know what I mean!

Who Needs These? ANC and ENC

There are two main types of noise cancellation: passive and active. Passive noise cancellation relies on physical barriers like ear cushions or in-ear seals to block out external sounds. Active noise cancellation (ANC) uses advanced electronics to counteract ambient noise. So, let’s see who needs this:

Who Needs ANC?

• Travellers: Ideal for frequent flyers and commuters who want to block out engine noise and chatter for a peaceful journey.
• Office Workers: Perfect for creating a quiet workspace in noisy environments, helping to improve focus and productivity.
• Music Lovers: Best for those who desire an immersive audio experience without the interference of external sounds.
• Students: Useful for studying in noisy environments like libraries or coffee shops.

Who Needs ENC?

• Remote Workers: Essential for those who often make calls or attend virtual meetings in noisy environments, ensuring clear communication.
• Business Professionals: Great for improving call quality during important business conversations.
• Voice Assistants Users: Beneficial for those who frequently use voice commands and want accurate recognition.
• Casual Users: Ideal for anyone who makes calls in busy settings and wants to ensure their voice is heard clearly.

ENC vs. ANC: Differences and Features

Active Noise Cancellation (ANC) and Environmental Noise Cancellation (ENC) are two distinct technologies used in modern earbuds and headphones, each serving different purposes and employing unique methods to enhance the user's audio experience. While both aim to reduce unwanted noise, they operate in fundamentally different ways and cater to distinct aspects of audio interaction.

To better understand the key differences between ANC and ENC, let's compare them in the following table:
