Dynamic noise reduction is a technique used in noise control that involves the use of adaptive algorithms to reduce unwanted noise from a signal. By analyzing the noise characteristics in real-time, the algorithm adjusts itself to effectively filter out the noise while preserving the desired signal. This advanced technology is commonly employed in various noise reduction applications, particularly in headphones, earphones, and automotive interiors, providing a quieter and more immersive audio experience.
