The evaluation and analysis of the uncertainty of laboratory measurement of airborne sound insulation have been carried out by Research Group for Acoustics and Vibration – National Standardization Agency of Indonesia (BSN). The aims of this work are to ev... see more

The use of double-sheet enclosures with an intermediate air chamber in façades guarantees a higher quality of acoustic insulation against external airborne noise. The effective advantages of the intermediate air chamber depend mainly on its airtightness a... see more

Outdoor noise barrier is roadside noise reducing device, the primary task of which is the protection of a predetermined sound protection area against road traffic noise. The examinations of acoustic properties of the elements used for construction of nois... see more

This paper presents a research activity focused on the development of a range of membranes based on distilled bitumen and polymers, specifically designed for high levels of noise insulation from airborne noise. These membranes can be used in multiple laye... see more

Radar exploration supports glaciological studies playing several roles in ice exploration such as determining ice thickness and volume, describing ice and snow internal layering and characterizing crevassed areas. The method, widely used with full success... see more

Laminated glass is one type of glass that is commonly used for sound insulation (walls or doors). Tests related to the ability of insulating glass in Indonesia are still sporadic. One of the places to do this test is the SNSU BSN Lab. This Lab has a funct... see more

The use of sound absorbers on many ships made from glass wool. Glass wool has a negative impact on health, which can irritate the skin and disrupt the respiratory system. Therefore, it is necessary to have an alternative sound insulation material that is ... see more

A sound reduction index (RIc) is a laboratory measurement of the sound insulating properties of a material or building element, commonly conducted using a reverberation chamber and an anechoic chamber (SIC), which requires high expenses. This study aimed ... see more

Original single-layer and multilayer structures of sound-insulating panels are considered, as well as their advantages compared to traditional analogs.The shortcomings of the method of optimization calculation of a group of sound-insulating panels designe... see more
