Active noise reduction is an advanced audio technology that can help users achieve a better auditory experience in various environments. Specifically, active noise reduction is the process of detecting and eliminating noise by utilizing the built-in microphone, diaphragm, and intelligent algorithms of electronic devices.
When using active noise reduction devices, the microphone will receive all the sound in the environment, and the algorithm will compare it with the required audio signal and calculate the corresponding noise reduction parameters. Then, these parameters are passed to the digital signal processor (DSP), which uses them to cancel out noise and make the desired sound clearer. Ultimately, users will hear audio that is closer to the original sound.
The application field of active noise reduction technology is very wide, which can be used to eliminate noise interference in various scenarios, including public places such as airplanes, subways, buses, cafes, restaurants, etc. In addition, active noise reduction devices are also widely used in quiet working environments, such as computer rooms, offices, and other places. It is gradually extended to consumer electronics such as music players, mobile phones, televisions, etc., to provide users with a better auditory experience.
In short, active noise reduction is a revolutionary technology that can help us work and live more comfortably in noisy environments.
