Is the Noise Level of Container Houses Loud?

The noise level of container houses depends on their structural design and materials. Well-constructed container houses can control noise within normal limits in typical environments, but the sound-conducting properties of metal may result in inferior sound insulation compared to traditional buildings, requiring additional measures to enhance performance. Detailed analysis is as follows:

1. Structural Design is Directly Related to Sound Insulation Performance
Measured data shows that container houses with fully welded box structures (such as Tongxiang Jiacheng Mobile Panel House products) have an internal noise level of 58 decibels in construction site machinery operation environments, meeting the standard for normal indoor conversation (typically 50-60 decibels is considered suitable). In contrast, bolt-connected box structures (such as Tongrun Integrated Housing products) reach 65 decibels under the same conditions, necessitating earplugs for rest. This indicates that welding processes enhance structural sealing, reducing sound penetration, while bolt connections may generate resonance noise due to gaps.

2. The Sound-Conducting Properties of Metal are a Major Drawback
Container houses primarily use steel frames, and metal's vibration conduction efficiency is significantly higher than that of concrete or brick structures. For example, Beijing Falilai products, lacking optimized sound insulation design, have internal noise levels 7 decibels higher than Jiacheng products, potentially affecting hearing health with prolonged exposure. This characteristic is particularly evident during rainy or windy weather, where raindrops striking metal roofs can produce sustained noise levels of 40-50 decibels.

3. Sound Insulation Performance Can be Improved Through Technical Measures
Some high-end products enhance sound insulation through structural optimization:

• Filling Sound Insulation Materials: Adding sound-absorbing materials like glass wool or rock wool in wall cavities can reduce noise by 10-15 decibels.
• Double-Wall Design: Using an inner and outer steel plate with an air gap in between leverages air damping effects to reduce sound transmission.
• Sealing Treatment: Applying rubber seals to door and window joints, as well as box connections, prevents sound leakage through gaps.
  For example, after filling special sound insulation materials in the side panels, Hunan Yianju Integrated Housing significantly reduced noise in the sensitive frequency range of 250-1000Hz.

4. Usage Scenarios Affect Noise Perception
In noisy environments like construction sites, the noise issues of container houses may be masked by ambient noise; however, in residential scenarios, sound insulation performance must be prioritized. For office or residential use, it is advisable to select products that have passed third-party testing and certification, and request noise test reports from manufacturers.
