Active Noise Cancelling (ANC) devices use destructive interference to cancel out unwanted noise. They work by using microphones to pick up external sounds, then generating anti-noise waves that are 180° out of phase with the original noise—effectively neutralizing it. ANC is especially effective at reducing low-frequency, consistent noise like airplane engines, car hums, or office air conditioning.
ANC comes in different forms, including headphones, earbuds, and even car systems. For example, some earbuds use intelligent ANC to track and eliminate background noise, while others combine ANC with ambient sound modes to let in important voices when needed. At Yigu Sourcing, we help you select ANC devices that match your noise environment—whether for personal use, travel, or industrial settings—ensuring you get effective noise control without compromising comfort or audio quality.
FAQ
Q: Why is ANC better at reducing low-frequency noise than high-frequency noise?
A: ANC relies on generating anti-noise that perfectly matches the frequency and phase of incoming sound. Low-frequency sounds have consistent, predictable wave patterns, making them easy to counter. High-frequency sounds, like voices or sudden noises, are irregular and change too quickly for ANC systems to generate matching anti-noise in real time.
