摘要

根据实际工作中的降噪工程案例，首先分析了有限空间内的噪声频谱特性，再根据噪声频谱特性进行了吸声设计，最后确定了穿孔板厚度，孔径，穿孔率等设计参数，取得了良好的降噪效果。 According to the case of noise reduction in practical work, the noise spectrum characteristics in finite space are analyzed, and then the sound absorption design is carried out according to the noise spectrum characteristics. Finally, the design parameters such as thickness, aperture and perforation of perforated plate are determined, achieving good noise reduction effect.

中央空调机房的噪声分析与共振吸声体设计 Noise Analysis and Resonant Absorber Design of Central Air Conditioning Room

根据实际工作中的降噪工程案例，首先分析了有限空间内的噪声频谱特性，再根据噪声频谱特性进行了吸声设计，最后确定了穿孔板厚度，孔径，穿孔率等设计参数，取得了良好的降噪效果。 According to the case of noise reduction in practical work, the noise spectrum characteristics in finite space are analyzed, and then the sound absorption design is carried out according to the noise spectrum characteristics. Finally, the design parameters such as thickness, aperture and perforation of perforated plate are determined, achieving good noise reduction effect.
