This paper presents an active noise control system for infant incubators. Experimental results show that global noise reduction can be achieved for infant incubator ANC systems. An audio-integration algorithm is presented to introduce a healthy audio (intrauterine) sound with the ANC system to mask the residual noise and soothe the infant. Carbon nanotube based transparent thin film speaker is also introduced in this paper as the actuator for the ANC system to generate the destructive secondary sound, which can significantly save the congested incubator space and without blocking the view of doctors and nurses.
本文提出了一种用于婴儿培养箱的有源噪声控制系统。实验结果表明，婴儿培养箱有源噪声控制系统能够实现整体降噪。提出了一种音频集成算法，将健康的音频（子宫内）声音与有源噪声控制系统相结合，以掩盖残余噪声并安抚婴儿。本文还引入了基于碳纳米管的透明薄膜扬声器作为有源噪声控制系统的执行器，用于产生相消二次声，这可以显著节省拥挤的培养箱空间，且不会遮挡医护人员的视线。
