⚡ 2. Quick Answer
ANC (Active Noise Cancellation) in earbuds is a technology that reduces unwanted background noise by using microphones and sound waves to cancel external sounds.
- Detects outside noise
- Generates opposite sound waves
- Cancels noise before it reaches your ears
👉 Result: Quieter, more immersive listening experience
🔬 3. How Does ANC Work in Earbuds?
Let’s break it down in a simple way.
🎯 Step-by-Step Process:
- Microphones pick up external noise
- Earbuds analyze the sound
- They create an “anti-noise” signal
- Both sounds cancel each other
👉 This is called destructive interference
🎧 Example:
- Engine noise in flights ✈️
- AC or fan noise 🌀
- Background chatter 🗣️
ANC works best on these continuous sounds
