Seoul, South Korea – The Korea Land and Housing Corporation (LH) has announced a significant breakthrough in its efforts to combat the persistent issue of noise between floors in apartment buildings. The state-run housing developer has successfully developed a new technology that reduces floor noise to levels comparable to a quiet library.

The innovative technology, which will be implemented in all new public housing projects starting next year, has been rigorously tested at LH's new state-of-the-art noise testing facility, the Decibel 35 Lab.

A Significant Improvement

Unlike traditional construction methods that often result in noticeable noise transmission between floors, LH's new technology significantly reduces noise levels. During a demonstration at the Decibel 35 Lab, researchers simulated various noise-generating activities, such as walking, running, and dropping objects, and measured the resulting noise levels.

The results were impressive. Even when a person ran on a treadmill or dropped a heavy rubber ball, the noise levels were barely perceptible. LH achieved this by increasing the thickness of the floor slabs and incorporating advanced soundproofing materials.

A Comprehensive Approach

In addition to reducing noise transmission, LH has also developed a "Noise Guard" system that alerts residents when noise levels exceed a certain threshold. This system can be retrofitted into existing buildings.

"Our goal is to create a living environment where residents can enjoy peace and quiet," said one official at LH. "By implementing this new technology, we can significantly reduce noise complaints and improve the overall quality of life for our residents."

Addressing the Cost Challenge

While the new technology is promising, it does come with an increased cost. LH estimates that upgrading to the new noise reduction standard will add approximately 4 million won to the construction cost of a 59 square-meter apartment.

To address this issue, LH plans to share its technology with smaller construction companies to help reduce costs and promote wider adoption. The Decibel 35 Lab will also be made available to the public and private sectors for testing and research.
