Noise-reducing Curtain

Noise pollution is a general concern in urban life. Noise-reducing Curtain is a kind of ultrasonic noise reduction equipment which employs active noise reduction method. First, it detects the intensity of noise outside the window by noise receptor, then the ultrasonic generator matrix generates directional ultrasonic beams with a frequency of 25kHZ and no more than 100 dB, which acts as the curtain covering the noise leakage area and change the amplitude of air vibration. Therefore, the noise’s intensity is reduced, and the indoor noise is lowered to 50 dB below, so people can enjoy a quiet indoor life.
