HDC Hyundai Development has introduced a quality control system that uses artificial intelligence to measure inter-floor noise in every apartment unit it builds. The aim is to improve construction quality by checking floor impact noise insulation across all units, going beyond legal requirements that call for testing only a sample.
The builder said on the 12th that it conducted on-site floor impact noise measurements at every unit in Gangbyeon Station Central IPARK. Using AI-based measurement and analysis technology, it reviewed insulation performance for each unit as well as variations across buildings and floors. The technology applied in the testing was developed through the Ministry of Land, Infrastructure and Transport's AX-SPRINT program, which supports the rapid commercialization of AI-applied products.
Gangbyeon Station Central IPARK had earlier recorded levels about 10 decibels below the legal standard of 49 decibels for both light-weight and heavy-weight impact noise in performance tests conducted by the Korea Authority of Land & Infrastructure Safety. For floor impact noise, a lower reading means better insulation.
The company has also strengthened inspections at each stage of the process, including design, material selection and construction. Because inter-floor noise performance is difficult to improve once floor structures are built, the approach is to identify factors that could degrade performance as each stage is completed.
"Inter-floor noise is hard to fix after residents move in, so thorough management is needed from the construction stage," an official at HDC Hyundai Development said. "Through measurements in every unit and AI analysis, we are verifying the performance of the spaces where residents actually live."
Starting with Gangbyeon Station Central IPARK, HDC Hyundai Development plans to expand the all-unit inter-floor noise measurement system to IPARK project sites nationwide, including in Cheonan, Gonjiam and Iksan.
