sound chamber

Expansion Chamber Type Sound-insulating Structure at Shaft Through Hole

轴孔扩张管隔声结构

The larger the air chamber of Ocarina is, the basic sound has lower pitch.

陶笛的共鸣气腔越大, 其基本音就越低.

Evaluation of the sound source power in high intensity sound reverberation chamber

高声强混响室声源声功率的估计

Combustion instability not only affects the stability of the aero-engine work, but also caused the combustion chamber flame tube thin-walled structure sound-vibration coupled fatigue.

燃烧不稳定不仅影响航空发动机的工作稳定性，而且还是造成燃烧室火焰筒薄壁结构声振耦合疲劳破坏的重要原因。

The paper establishes reverberation-anechoic chamber sound insulation test method via lot of test research and demonstration.

本文通过大量的试验研究与论证,建立了混响室—消声室法隔声测量方法,填补了国内在该领域研究的空白.
