Active noise control is an audio technology designed to reduce noise and interference in the surrounding environment. This technology uses different methods and algorithms to detect and filter out non human vocal noise, providing a clearer, more detailed, and more perfect listening experience. Active noise control can be applied to various devices, such as headphones, speakers, mobile phones, etc.
The principle of Active noise control is to use a microphone and built-in electronic components to monitor the sound in the surrounding environment, and use specific algorithms to generate reverse sound waves. The calculation of this type of sound wave is based on as much noise information as possible in the environment. Reverse sound waves are sent to headphones or speakers to counteract noise in the surrounding environment.
Active noise control technology has become the standard configuration of many high-end headphones and speakers, because it can provide a higher quality audio experience, especially in noisy environments or on the road. In addition, it can also be used in some applications, such as video conferencing, speech recognition, aviation, and consumer devices. However, some people believe that they may cause hearing loss, so attention should be paid to the details of their use.
