摘要
静音箱在噪声控制中有良好的降噪效果。根据噪声源的分布及控制特点,把箱体内噪声控制分为四个控制区。根据不同分区内噪声的特点,在不同控制区分别采用隔声、吸声和消声等噪声控制技术。在箱体尺寸受限制的条件下,利用有限的空间实现了较大的降噪量,取得了良好效果。
It is resulrful to apply the sound attenuated enclosure to controlling undesired .sound. According to the distribution of noise source and characteristics, the enclosure is divided into four control regions. Noise isolation, noise absorption and muffling are individually applied to each region in accordance with their feature. Under the limited size of the enclosure, the higher noise reduction is obtained in limited space, and good effectiveness is gained.
