Impact sound insulating performance of access floors

The Journal of the Acoustical Society of America, 2008
Access floor are raised floor systems consisting of modular panels supported by posts at a certain height to create a gap below the floor surface. Electrical wires and pipes can be placed inside the gap in order to avoid exposed installations and to simplify operations involving the inspection, repair, changing, or adding of system elements.

Sound insulation performance in shipboard

The Journal of the Acoustical Society of America, 2001
This work deals with correlation between the field sound transmission loss (FSTL) in cabins and the sound transmission loss (STL) in reverberation chambers. To this end, experimental investigations are carried out on various ships such as a passenger, a plant ship, and a container ship. Comparisons of FSTLs and STLs indicate that a passenger ship shows

Sound Insulation Performance of Composites Developed using Waste Carbonaceous Materials

INTER-NOISE and NOISE-CON Congress and Conference Proceedings, 2023
Mitigating vibration in a system has many advantages, from decreasing noise output to increasing component life. Therefore, it is necessary to eliminate the mechanical vibration and sound through appropriate measures. State-of-the-art techniques seeks the utilization of sustainable carbonaceous resources for the development of sound insulating ...

Sound Absorption Performance of Membrane Covered Insulators

SAE Technical Paper Series, 2001
<div class="htmlview paragraph">Molded fiberglass hood insulators (hoodliners) and engine side dash insulators (dashliners) are widely applied in vehicles for noise control. These absorptive components reduce reverberant “build-up” in the engine compartment and thus cut the noise transmission into the passenger compartment. Due to restrictions of

Sound Insulation Performance of Finite Orthotropic Sandwich Panels

Applied Mechanics and Materials, 2013
A theoretical model for calculating sound transmission loss (STL) of finite honeycomb sandwich panels is developed. The accuracy of the theoretical predictions is checked against experimental data, with good agreement achieved. Numerical analysis shows that increasing face sheet thickness can improve STL effectively, which is much more effective than ...

BIM-based sound insulation performance evaluation of interior walls

The Journal of the Acoustical Society of America, 2023
As a general contractor, acoustical design confirmation of a project at construction stage is rather limited especially if it is large-scale. Among others, many interior walls of the building projects are found to be improperly designed in terms of sound insulation in that chances are hardly given for the most projects to be intervened by an acoustic ...

Performance Equivalent Thickness of a Sound Insulation System

SAE Technical Paper Series, 2013
<div class="section abstract"><div class="htmlview paragraph">Vehicle sound insulation systems, such as front of dash mats or carpet assemblies, etc. play a key role in controlling vehicle interior noise. However, dash and carpet insulators are often designed to have varied thickness in compliance with packaging constraints or to fulfill ...

Low impact renovations with high performance sound insulation

The Journal of the Acoustical Society of America, 2005
Architectural renovations, although often driven by visual objectives, are a good opportunity to pursue acoustical interventions involving both sound intrusions into a space, and sound quality of the acoustic environment within the space. A high priority is to keep the construction impact low as it affects both project cost and schedule.

Study on Sound Insulation Performance of Vehicle Dash Reinforcements

SAE Technical Paper Series, 2014
<div class="section abstract"><div class="htmlview paragraph">Dash panel is the most important path of structure-borne and air-borne interior noise for engine-driven vehicles. Reinforcements, which are added to dash panel, are mainly designed in order to suppress the structure-borne noise contribution from the dash panel.</div><div
