亥姆霍兹共振器
[声] helmholtz resonator
- 另一是使用压力脉动消减器，如末端封闭的支管、膨胀室、气室、亥姆霍兹共振器、蓄能器……等。
The other way is to apply a pressure fluctuation absorber, such as a branch pipeline with closed ends, an air chamber, an expansion chamber, a Helmholts resonator, an accumulator. - 而静电纺纤维的多孔结构可以看做许多亥姆霍兹共振器的组合，能通过共振大幅吸收各种频率，特别是常规吸声材料难以吸收的低频波段的能量，同时大大提高了吸声频率的带宽。
Through this ability, which is also based on the resonance effect of nanofibrous layer damped in fibrous nonwoven web, it surpasses to date known materials in sound absorption of low frequency. - 文中提出了可调频式亥姆霍兹共振式消声器的五种结构设计方案，并逐一进行了仿真计算分析，结果表明：共振器颈部横截面积的改变对共振频率的影响较大。
In this paper, five schemes of variably tuned Helmholtz resonator were proposed and simulated detailedly, the results shows that changing the neck area affects the resonant frequency significantly.
