消声器是安装在空气动力设备气流通道上或进、排气系统中的降低噪声的装置。消声器能够阻挡声波传播 ,允许气流通过 ,是控制噪声的有效工具。将消声器用于化学实验室系统 ,能够有效地解决排气噪声问题。下面介绍一种抗性消声器。抗性消声器的特点是设有敷设吸声材料 ,不像阻性? Silencers are noise-reducing devices installed in the air flow path of aerodynamic equipment or in the exhaust system. Mufflers block the propagation of sound waves and allow airflow to pass through, making them an effective tool for noise control. Using mufflers in chemical laboratory systems can effectively solve the problem of exhaust noise. Here’s a resistant muffler. Resistant muffler is characterized by laying a sound-absorbing material, unlike the resistance?
