Have you ever been on an important call and had to say, "Sorry, can you repeat that?" because of background noise? Whether it's a barking dog, chatty coworkers, or just street noise, background sounds can really mess with your ability to communicate clearly. That’s where ENC comes in — Environmental Noise Cancellation.
In this blog, I’ll walk you through the real meaning of ENC, how it works, how it compares to ANC, and why we at Nuroum believe it’s essential in modern work and meeting environments. Whether you’re working from home, in the office, or in a coffee shop, understanding ENC could change how you choose your next headset or camera. Let’s dive in.
What is the Meaning of ENC?
Breaking Down ENC: Environmental Noise Cancellation
ENC stands for Environmental Noise Cancellation, and it’s exactly what it sounds like — technology that reduces external environmental sounds during a call or recording. Unlike noise isolation or passive noise control, ENC actively detects and suppresses the background sounds around you, making sure your voice remains front and center.
It’s especially useful in professional communication settings where clarity is everything. When you’re presenting, leading a virtual meeting, or just chatting with your team, ENC ensures that your voice is clean, sharp, and easy to understand, no matter what’s going on around you.
How ENC Differs From ANC (Active Noise Cancellation)
This is one of the most common questions we get: what’s the difference between ENC and ANC?
- ENC (Environmental Noise Cancellation) focuses on filtering out the background noise on your side of the call. It makes your voice sound clearer to the person you're talking to.
- ANC (Active Noise Cancellation) is designed for your listening experience. It reduces the noise that you hear, like engine noise on a plane or chatter in a cafe.
In short, ENC is for talking, ANC is for listening. And when it comes to meetings, interviews, or podcasts — ENC is the real MVP.
How Does ENC Technology Work? (ENC noise cancelling, environmental noise cancellation)
Built-in Microphones and Real-Time Audio Processing
ENC works using multiple microphones strategically placed around the device. These mics capture ambient sound in real-time. Then, with the help of digital signal processing (DSP), the device filters out those noises and ensures that only your voice is transmitted.
It’s kind of like having a smart audio assistant constantly listening and removing the stuff that doesn’t matter. So, when you’re talking on a call and someone starts vacuuming in the next room, ENC keeps your voice sharp and cuts out the chaos.
Filtering Background Noise vs. Voice Focus
The magic of ENC isn’t just about noise reduction — it’s about voice prioritization. The technology doesn’t just block sound; it actively distinguishes between your voice and everything else. Then it enhances your voice and reduces everything else.
This is especially valuable in group settings or open-plan offices where there’s constant background noise. Your device becomes a smart gatekeeper for your audio.
ENC in Headphones vs. ENC in Conferencing Devices
While ENC is most commonly found in headphones and earbuds, it's increasingly popular in video conferencing devices too.
- In headphones like our HP31D ENC Bluetooth Headset, ENC ensures your voice is clear even during gaming or team calls.
- In all-in-one conferencing systems like the Camera 360 Pro, ENC helps reduce noise in the meeting room, ensuring your entire team sounds sharp on the other side.
