ANC (Active Noise Cancellation) is a technology in headphones that:

• Detects external noise using microphones
• Generates opposite sound waves
• Cancels unwanted noise in real-time

👉 Result: You hear less background noise and more of your audio clearly.

🧠 What is ANC in Headphones

🎯 How ANC Actually Works (Simple Explanation)

ANC headphones use tiny microphones to listen to outside noise.

Then:

1. The headphone detects noise (like engine sound)
2. It creates an “opposite” sound wave
3. Both cancel each other out

👉 This process is based on a concept called sound wave inversion

Real-life effect:

• Constant noises → disappear
• Music becomes clearer at lower volumes

🔊 Types of Noise ANC Works Best On

ANC is not magic — it works best for specific types of sounds:
