Windproof active noise reduction silicon microphone heads are currently widely used with the rise of 5G, smart home, and smart city construction. Before introducing active noise reduction silicon microphone heads, let's first understand active noise reduction technology and what it means. The principle of active noise reduction is to add a circuit for noise analysis in the circuit. Through DSP fast operation and analysis, an algorithm that can offset external noise is generated, and then the phase is adjusted to output in reverse from the device. The method of achieving noise elimination is called active noise reduction technology.
