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 ...

Evaluating Laboratory Measurements for Sound Insulation of Cross-Laminated Timber (CLT) Floors: Configurations in Lightweight Buildings

Applied Sciences, 2022
Cross-laminated timber (CLT) floors with supplementary layers or floating floors comprise a common solution in new multistory timber structures. However, bare CLT components provide poor sound insulation, especially in low frequencies during structure ...

Measurement of Impact Sound Transmission Through Floors [PDF]

The Journal of the Acoustical Society of America, 1940
Existing methods of measuring the transmission of impact noise through floors and of stating the results are inadequate in two respects: (1) Published data give the difference in intensity of impact noise measured above and below a given floor construction, but do not permit an accurate comparison of the noise transmitted by different constructions. (2)

Innovative solutions to improved sound insulation of CLT floors

Developments in the Built Environment, 2023
Building with cross laminated timber (CLT) has gain increased interest over the last years, but in common to other wood-based building systems, inadequate low-frequency sound insulation is seen as a problem.

Experimental investigation of the low-frequency impact sound transfer function of lightweight wooden floors via heel drops

Acta Acustica, 2020
The lightweight floor is a popular construction choice in buildings despite its poor low-frequency impact sound performance. This is exacerbated by common human activities, such as walking and jumping, that have high input force levels at low frequencies.

Subjective evaluation of floor impact noise using the tapping machine and a non-standardized source

Acta Scientiarum: Technology, 2022
Assessing the acoustical performance of building floor systems relies on the impact source to be utilized and on the type of floor cover used. Besides that, a reliable assessment should consider the listeners´ judgments of the sounds transmitted through
