Description
The global active noise cancellation IC market is growing at a CAGR of 14% from 2022 to 2028. The increasing awareness of hearing disorders, the transition to audible in the connected environment, the growing number of smartphone people and tech-savvy consumers, and the latest audio technology are major factors expected to drive the active noise cancellation (ANC) headphones market.
What is Active Noise Cancellation IC?
Active Noise Cancellation (ANC) utilizes a noise-canceling system to decrease undesirable background noise. The system is based on microphones that “hear” the sounds outside and inside the earphone, an ANC chipset reversing the sound waves and a speaker inside the earphone canceling the external sound by neutralizing sound waves. A while like taking +2 outside and adding -2 inside to create zero. Active noise cancellation can be processed via the ANC chipset operating either: – a feed-forward ANC system has a microphone which is positioned on the outside of the earphone – a feed-back ANC system has a microphone which is positioned on the inside of the earphone – a hybrid ANC system is a mixture of a feed-forward and a feed-back ANC system.
