Hyundai Construction Launches 'H Silent Lab,' a Frontline Base for Interfloor Noise Control

[Asia Economy Reporter Cha Wanyong] Hyundai Engineering & Construction announced on the 2nd that it has established a specialized research facility for inter-floor noise at the Mabuk Technology Research Complex located in Giheung-gu, Yongin-si, Gyeonggi-do, and built the comprehensive 'H Silent Lab' capable of conducting research from technology development to verification.

The H Silent Lab serves as an advanced base for commercializing Hyundai Engineering & Construction's first-grade floor system. It conducts research to secure long-term quality, such as real-time monitoring of internal environment (temperature and humidity) changes and durability evaluation through repetitive load testing. By building a database measuring vibrations and noise under various conditions within units, such as floors and ceiling finishes, it aims to enhance prediction accuracy, advance first-grade technology, and apply it early on-site.

The H Silent Lab, a four-story building with a total of seven units, can verify not only inter-floor noise performance according to floor structures (slab, ondol layer, cushioning system combinations) but also sound insulation performance of lightweight walls. In addition to the 'wall-type structure' applied in most apartments in Korea, it is composed of 'PC Ramenjo,' which allows easy modification of unit size, to study noise transmission characteristics depending on wall conditions while simultaneously developing technology.

Ramenjo is composed of external columns and beams without partition walls, allowing flexible floor plans and high space utilization. It is expected to enhance residential marketability by reflecting various customer needs in the future.

In particular, the Ramenjo installed in the H Silent Lab applied the PC (Precast Concrete) method, where concrete building materials are prefabricated at the factory, transported to the construction site, assembled, and constructed. This reflects Hyundai Engineering & Construction's development will to lead changes in the construction industry through the OSC (Off-Site Construction) method, improving quality and safety to realize the highest residential value.

A Hyundai Engineering & Construction official stated, "Following inter-floor noise reduction technologies centered on materials and construction methods, we are expanding technology development to consider floor plans and structures, aiming to realize inter-floor noise reduction housing that satisfies customers with differentiated residential technology and quality through broad technology development." He added, "We will closely cooperate with public institutions in line with the government's strengthened inter-floor noise verification system policy to enhance future residential competitiveness and take the lead in solving social issues."

Meanwhile, Hyundai Engineering & Construction laid the foundation for technology commercialization by obtaining the first-grade certification for both lightweight and heavyweight impact sound in the floor impact sound performance grade evaluation conducted by the Ministry of Land, Infrastructure and Transport's accredited institution in August last year, becoming the first domestic construction company to do so.
