Ulsan City to Address Interfloor Noise... Strengthening Reduction Measures

Raising Floor Standards for Apartment Complexes with Over 500 Units

Introducing Resident-Specialized Spaces Such as Guesthouses

Ulsan City has stepped up to devise measures to reduce noise between floors.

On the 15th, Ulsan City announced that starting this year, for housing construction project approvals involving 500 or more households, it will establish and apply significantly strengthened floor standards compared to the current design criteria to drastically reduce noise between floors in multi-family housing.

According to the newly established standards, the criteria for lightweight and heavyweight impact noise will be strengthened from grade 4 (49dB or below) to grade 1 (37dB or below) and grade 3 (45dB or below), respectively, based on the pilot complex standards of Korea Land and Housing Corporation (LH).

Lightweight impact noise refers to the noise generated when light objects are dropped or chairs and desks are dragged, while heavyweight impact noise refers to the noise generated when children jump.

Ulsan City plans to recommend the strengthened standards during the review of housing construction project applications and include them as approval conditions upon project approval. At the construction stage, detailed floor structure drawings will be reviewed to confirm whether the standards are applied.

During quality inspections of multi-family housing, the city will check the certification of floor impact noise blocking structures, construction detail drawings, and performance test results to proactively address noise issues between floors and provide a comfortable living environment.

Additionally, to improve residential satisfaction, Ulsan City will promote the introduction of customized specialized spaces for residents in housing construction projects with 500 or more households.

Specialized spaces include guest houses, outdoor camping sites, kids’ water parks, and indoor/outdoor multipurpose sports facilities, and their installation will be recommended during the housing construction project review process.

The introduction of customized specialized spaces has already been applied in IS Dongseo’s Deokha District Aileen’s Garden Phase 1 and 2, and Woomi Construction’s Ulsan Down District 2.

Ulsan City plans to monitor resident preferences in these complexes where customized designs have been applied and explore expansion plans accordingly.

An official from Ulsan City stated, “The reduction of noise between floors and the introduction of customized specialized spaces are being promoted to create a pleasant living environment,” adding, “We hope construction companies will also adhere to the strengthened standards to resolve noise issues between floors.”
