Introduction
In today's fast-paced digital world, clear and uninterrupted communication is more important than ever. Whether you are working remotely, attending virtual meetings, gaming, or simply catching up with loved ones over the phone, background noise can be a major challenge. This is why noise cancellation technology plays a crucial role in ensuring smooth and effective conversations.
Two popular noise cancellation technologies are Active Noise Cancellation (ANC) and Environmental Noise Cancellation (ENC). Both of these technologies work to reduce background noise, but they do so in different ways and serve different purposes. If you are looking for the best noise cancellation option for calling, you might be wondering: Which is better, ANC or ENC?
This comprehensive guide will explain the working principles, differences, advantages, and disadvantages of ANC and ENC. Additionally, we will discuss the best headsets and earbuds equipped with these technologies and guide you on how to choose the right one for your needs. By the end of this article, you will be able to make an informed decision about which technology suits you best for calling purposes.
What is Active Noise Cancellation (ANC)?
How Does ANC Work?
Active Noise Cancellation (ANC) is an advanced technology that reduces unwanted ambient noise by using built-in microphones and anti-noise sound waves. This process works as follows:
- Microphone Detection: The device has built-in microphones that capture surrounding noise.
- Sound Wave Analysis: The noise is analyzed by the device’s processing unit.
- Anti-Noise Generation: The system generates an opposite (anti-phase) sound wave to cancel out the external noise.
- Noise Reduction: When the original noise and anti-noise interact, they neutralize each other, effectively reducing unwanted sounds.
Types of ANC
There are three main types of Active Noise Cancellation:
- Feedforward ANC: Uses an external microphone to detect and cancel noise before the user hears it.
- Feedback ANC: Uses an internal microphone placed inside the ear cup to cancel noise after it enters the ear.
- Hybrid ANC: A combination of both feedforward and feedback ANC for the most effective noise cancellation.
Best Use Cases for ANC
ANC is most effective in environments where constant, low-frequency noises are present. This includes:
- Airplanes (engine noise)
- Offices (air conditioning, chatter, office equipment sounds)
- Public Transport (bus and train noise)
- Busy Streets (background traffic sounds)
Since ANC primarily eliminates low-frequency background noise, it works best when listening to music, podcasts, or audiobooks, allowing the user to focus without distraction.
What is Environmental Noise Cancellation (ENC)?
How Does ENC Work?
Environmental Noise Cancellation (ENC) is designed to improve the voice clarity of the user during calls by filtering out external noise. Unlike ANC, which is intended for the listener’s experience, ENC ensures that the outgoing audio (your voice) is clear and free from distractions.
ENC functions through the following process:
- Microphone Array: ENC-enabled devices use multiple microphones to pick up both the user’s voice and ambient noise.
- AI Noise Filtering: The system uses AI algorithms to differentiate human speech from background noise.
- Voice Enhancement: The microphone prioritizes the user’s voice, ensuring it is louder and clearer than background sounds.
- Noise Suppression: The device automatically reduces or eliminates unwanted noises like wind, keyboard typing, and other disturbances.
Best Use Cases for ENC
ENC is specifically beneficial in scenarios where voice clarity is critical. Some common situations include:
- Online Meetings & Conference Calls (Zoom, Microsoft Teams, Google Meet)
- Customer Service Calls & BPO Work
- Gaming & Streaming (Discord, Twitch, Xbox Live)
- Hands-Free Calling in Noisy Environments (Cafes, Streets, Public Transport)
ENC is especially popular among professionals, gamers, and frequent callers, as it ensures their voice remains crisp and clear without any background noise disturbances.
Key Differences Between ANC and ENC
| Feature | ANC (Active Noise Cancellation) | ENC (Environmental Noise Cancellation) |
|---|---|---|
| Primary Function | Cancels background noise for the listener | Enhances voice clarity for the caller |
| Technology Used | Anti-noise sound waves | AI noise filtering |
| Best For | Music, travel, focus work | Calls, gaming, online meetings |
| Noise Type | Continuous, low-frequency noise (e.g., engines, AC) | Sudden & background noises (e.g., people talking, keyboard typing) |
| Microphones Used | 1-2 external microphones | 2-6 microphones for better voice clarity |
| Effectiveness | Works best in low-frequency noise conditions | Works in varying noise levels |
Which is Better for Calling: ANC or ENC?
When it comes to calling and voice communication, ENC is the superior choice because it focuses on improving your voice clarity while minimizing background disturbances. ANC, on the other hand, is more suited for blocking external noise while listening to audio.
If your primary need is attending virtual meetings, gaming, or making business calls, then ENC-equipped headsets or earbuds are the best option. These devices will ensure that your voice is transmitted clearly without any distractions from background noise.
However, if you work in a noisy environment and need to focus without distractions, ANC headphones will be more effective for personal use. Keep in mind that ANC does not enhance the voice quality on calls—it simply reduces the background noise you hear.
How to Choose the Right Noise Cancellation Technology
If you are looking for the best noise cancellation based on your needs, consider the following:
- For Work Calls & Meetings: Choose an ENC-enabled headset to ensure clear voice transmission.
- For Music & Travel: Select ANC headphones to block out distractions.
- For Hybrid Use (Both Calls & Listening): Opt for a headset with both ANC & ENC capabilities.

Conclusion
Both ANC and ENC play important roles in noise cancellation, but they serve different purposes. If your main concern is voice clarity for calling, then ENC is the best choice. It ensures that your voice is transmitted clearly while filtering out unwanted background noise. On the other hand, if you want to enjoy music or work without distractions, ANC is the better option.
For the best of both worlds, consider investing in a device that supports both ANC & ENC, ensuring a superior communication and listening experience in any environment.
