How to Install Active Noise Cancellation in a Car?

[VanJeremiah]

Active noise cancellation refers to the situation where, after the engine starts, there is significant noise whether the audio system is on or not, and this can only be eliminated by visiting a 4S shop. More detailed information is as follows: 1. Active noise cancellation in cars refers to the generation of reverse sound waves equal to external noise by the noise cancellation system, thereby neutralizing the noise and achieving the effect of noise reduction. Active noise cancellation is a noise reduction technology that, in addition to being applied in cars, can also be used in noise-canceling headphones. 2. Of course, active noise cancellation has many limitations. This type of active noise cancellation belongs to active noise control within a closed space. Due to the increase in the noise cancellation space, the computational load required for implementation grows very quickly. In the case of a single processor, it is difficult to achieve the effect of active noise cancellation, so it can only be controlled by multiple processors. However, the challenges of algorithm distribution and data segmentation among processors make the noise cancellation project very difficult to implement.
