Active noise control technology of Air Circulation Fan

Active noise control technology is an innovative approach that aims to actively intervene and reduce the noise generated by the fan system through electronic or mechanical means. Active noise control technology of air circulation fan has the following four main features:
Anti-phase noise technology: One of the core of active noise control is anti-phase noise technology, which introduces sound waves opposite to the main noise spectrum in the fan system to offset and reduce the propagation of noise. This technology requires precise sensors and real-time feedback control systems to ensure the accuracy and effectiveness of the anti-phase signal.

Intelligent control system: Modern fan designs often use intelligent control systems to achieve active noise control. These systems can dynamically adjust noise suppression strategies based on ambient noise levels and fan operating conditions to provide better acoustic performance and user experience.

Sensor technology: Active noise control relies on high-precision sensors to monitor the noise output of the fan system in real time. These sensors can measure the frequency, intensity and direction of sound, providing accurate and useful feedback data for the control system.

Software algorithms and real-time processing: In order to effectively implement active noise control, fan designs usually use advanced software algorithms and real-time signal processing technologies. These technologies can quickly analyze sensor data and generate corresponding anti-phase noise signals to minimize the propagation and impact of noise.
These technologies are not just simple acoustic isolation or the application of sound-absorbing materials, but also the use of advanced control strategies and sensor technologies to monitor and adjust noise levels in real time, thereby improving the product's acoustic performance and user experience.
