Timber is growing more popular as a construction material nowadays. Indeed, it sustainable, user-friendly and widely available. However, homeowners of timber buildings still complain perceived indoor noise, specifically upon impact. Thus far, very little research has been conducted into this issue. This paper reports the results acoustic measurement campaign, in laboratory, on 14 different floating floors laid 200 mm cross-laminate slab. Results clearly demonstrate that neither literature...
Equipment, sound sources, operators, microphone placement, calculation techniques, and thermal–humidity measurement conditions all have an impact on the of impulse responses when several channels are present. However, variable, which is a significant component these factors impacting assessment acoustic characteristics, commonly overlooked in research. The effects altering temperature, relative humidity, air velocity parameters investigated this paper through experimental activities carried...
Estimation of the impact sound insulation horizontal partitions, evaluated from performance basic components according to EN 12354-2, does not provide satisfactory results when applied floors made Cross-Laminated Timber (CLT) elements. One most interesting reasons for this limited match between predicted and measured noise values is difficulty correlating reduction pressure level floor covering, in a laboratory on concrete slab, with actual behavior bare CLT floor. Reported here are...
Clay hollow brick walls are still popular in building industry, but the prediction of their sound insulation properties is not straightforward due to inhomogeneous and anisotropic characteristics. In this article, a classic approach has been used determine transmission coefficient walls, assuming an orthotropic behaviour deriving mechanical dynamic characteristics from datasheet information. Different types with horizontal vertical mortar joints have analysed. Experimental measurements...
Composite panels are being increasingly used in many applications because they can combine several interesting properties, such as high load-bearing capacity, low weight, and excellent thermal insulation. Different core materials be for composite sandwich panels, like polystyrene, mineral wool, polyurethane, glass or rigid phenolic foam, which is considered the plastic foam with best fire-proof properties. During research development phase, use of simulation tools often required improvement...
In order to ensure acoustic comfort of living spaces, nowadays façade systems having high performance are required. Within such context the glazing play a key role in achieving levels sound insulation. The characteristics insulation can be determined by analytical methods that make use experimental characterizations physical and mechanical parameters these systems. this work combined approach for transmission loss prediction is presented. particular, properties monolithic multilayer glasses...
Cross-Laminated Timber (CLT) is a building technology that becoming increasingly popular due to its sustainable and eco-friendly nature, as well availability. Nevertheless, CLT presents some challenges, especially in terms of impact noise airborne sound insulation. For this reason, many studies focus on the vibro-acoustic behavior elements, understand their performance, advantages limitations. In paper, 200 mm floor has been characterized laboratory, according ISO standards, by three...
High sound insulation façade requirements in contemporary buildings, led to the development of high-performance multilayer glazing systems. In this work a combined experimental and analytical approach has been adopted predict transmission loss systems made glass PVB layers, which are used several engineering areas (building, transportation, etc.). particular, mechanical properties have measured using resonance curve method flexural waves on beams with different boundary conditions. order...
Gypsum board walls are widely used in today’s buildings. A possible way to considerably increase the sound insulation performances of such lightweight is apply double-layer gypsum panels screwed together. Being boards separated by a thin air gap, there no shift critical frequency from single-layer case. Moreover, it obtain an improvement provided additional mass given double layer. The layer is, however, responsible for loss acoustic performance due cavity resonance effect range between 800...
The appropriate acoustic insulation project of building façades is importance for the design highly comfortable living environments. In some countries, national regulations require maximum noise levels inside rooms, or minimum sound limits, to be respected. a façade usually performed according ISO 12354-3 standard, which presents calculation method based on geometry room, shape façade, areas and performances individual elements. prescribed limits must experimentally verified methods derived...
The indoor air quality inside living spaces is a fundamental factor in providing adequate comfort. In order to do this, minimum exchange must be ensured. This can obtained by means of natural or mechanical ventilation using the Controlled Mechanical Ventilation system (CMV). CMV ensures better energy performance, as winter period, warm that comes out building preheats cold enters, and opposite occurs summer period. A possible problem with noise fans due movement electric motor rotation. work...
