Effect of steel fiber reinforced concrete on the heavy-weight floor impact sound performance

Journal of Asian Architecture and Building Engineering
In South Korea, where apartment buildings in which the slabs of each unit are shared by the upper and lower floor units have become common, noises due to the floor impact sound from slabs between upper and lower floor units are coming to the fore as a ...

Impact Sound Reduction Performances of Additional Floor Mats for the Retrofitting of an Existing Apartment Building in Accordance with Test-Bed Conditions

Applied Sciences
Floor mats are commonly used to improve the impact sound performance of existing homes, but actual impact sound reductions do not consistently appear, as they depend on the test-bed conditions used to determine impact sound performance.

Prediction of Vibration-Mode-Induced Noise of Structure–Acoustic Coupled Systems

Applied Sciences, 2022
The exposure of a structure to an acoustic domain induces a sound field owing to the interaction of the air-fluid and structure at the acoustic–structure boundaries.

The Improvement in the Floor Impact Noise with Changes in the Glass Transition Temperature of an SBR Latex Mortar

Applied Sciences
It is most effective to reduce floor impact noise as close to the sound source as possible. In apartments, there are multiple layers in the floor system, from floor finishing to the structural concrete slab. Apart from the floor finishing, mortar lies at
