Professional Hybrid Active Noise Cancelling (FB & FF) Technology
Active noise cancellation (ANC) is the process of using a microphone to monitor environmental noise and creating anti-noise that’s then mixed in with audio playback to cancel noise entering the user’s ear. Active noise cancellation can be achieved with analog filters or digital filters and is generally differentiated by architecture:
Feed-forward cancellation (FF): Commonly in in-ear earphones. Characterized by a large noise reduction bandwidth but small noise reduction depth, it is suitable for reducing medium frequency noise such as human voice in life.
Feedback cancellation (FB): Commonly in on-ear headphones. Characterized by small noise reduction bandwidth but large depth, it is suitable for eliminating low-frequency noise from aircraft, subway, car engines, etc.
Hybrid cancellation (Hybrid): Hybrid=FF+FB. The quality is good, but the price is high.
