How is the ventilation performance of the soundproof work pod?

Analysis of Ventilation Performance of soundproof work pod
Silent ventilation system:
High end models (such as Zhuoting Acoustics) adopt a maze style noise reduction design, and the ventilation noise can be controlled below 25dB, far exceeding the 35dB noise reduction requirement.
Some products (such as Anjing Sleep Cabin) achieve low noise operation of 27-48dB through HEPA13 filter and microporous array technology.
Fresh air exchange rate:
The mainstream product has a ventilation rate of 240m ³/h (such as a screen type soundproof room), meeting the demand of 200-450m ³/h.
Some models (such as K5 fresh air fan) support a large air volume of 500m ³/h, but need to balance sound insulation and ventilation efficiency.
Technical support:
The patented ventilation system (such as Zhuoting Acoustics) maintains a ventilation rate of 240m ³/h at a sound insulation level of 45dB, avoiding sacrificing ventilation due to sound insulation.
Some products achieve 20 air changes per hour through negative pressure design (such as CNAS certified cabin), while the noise level is less than 55dB.
Conclusion: High quality soundproof work pods can simultaneously meet the requirements of low noise (≤ 35dB) and high air exchange capacity (≥ 200m ³/h), and brand models with noise reduction and ventilation technology should be prioritized.
