Sound insulation of lightweight wooden floor structures: ANN model and sensitivity analysis.

INTER-NOISE and NOISE-CON Congress and Conference Proceedings, 2023
The artificial neural networks (ANN) approach is applied to estimate the acoustic performance for airborne and impact sound insulation curves of different lightweight wooden floors.

Sound insulation prediction method for single and spot laminated multilayer panels

Building Acoustics, 2022
Single-leaf panels made from homogeneous and isotropic materials are commonly used in buildings. However, it is often necessary to add various layers of the same or different materials in order to increase the acoustic insulation. This article presents a

Sound insulation of a hollow concrete blocks wall made with construction and demolition waste and wood-based panels as linings

Building Acoustics, 2021
It is a well-discussed topic that Construction and Demolition Waste (CDW) can be recycled and used as aggregate in the construction sector. Generally, Brazilian construction techniques are based on hollow blocks or bricks and mortars as coating systems ...

Advanced lightweight steel floor towards high sound insulation and fire resistance

Journal of constructional steel research, 2020
Industrialized lightweight buildings have great advantages associated with lower indirect costs, minimum construction wastes and faster construction processes. However, their main weaknesses lie in their acoustic performance and fire resistance.

A hybrid test method for measurement of airborne sound transmission loss of building partitions and elements

Journal of the Acoustical Society of America
Single-number ratings, such as sound transmission class (STC), outdoor to indoor transmission class (OITC), and weighted sound reduction index (Rw), have been widely used to indicate the sound transmission properties of the building elements.

A sound insulation prediction tool and LCA: A comparative study considering different wooden assemblies

INTER-NOISE and NOISE-CON Congress and Conference Proceedings
This paper aims to develop an acoustic design methodology for CLT floor assemblies using artificial neural networks approach by integration of life cycle assessment (LCA). 72 Lab-based measurements are used to develop the acoustic prediction tool.

Are single number ratings for sound insulation requirements still up-to-date?

INTER-NOISE and NOISE-CON Congress and Conference Proceedings
In general, soundproofing requirements are given in form of a single number rating. Individual values are therefore singular, i.e. precise, so that no uncertainties are taken into account when checking the quality by measurement or calculation.

Lithuanian experience of application the masonry cavity walls in multistory buildings with sound insulation requirements

Applied Acoustics, 2019
Cavity walls could be used instead of homogeneous walls in order to reduce the load acting on the ceiling structure while ensuring conformity with the acoustic requirements for buildings.

Massive or lightweight? Sound insulation of Austrian multistory apartment buildings since 2000

Journal of the Acoustical Society of America, 2019
During the past centuries, Austria was a country of massive multistory apartment houses. Since the last decade of the last century, technical and legal developments led to experimental multistory buildings with lightweight construction as timber frame or
