Sound insulation design for structural glazed façade is an important task in environmental noise control, as increased continuously repeated a significant factor impacting on people’s well-being and associated with negative impact their health. For façades, addition to sound insulation, requirements safe use high energy efficiency are also usually raised, which partly determine the composition ...

In the past few decades, the issue of environmental quality in the urban environment is a recurring theme. Green walls and roofs have demonstrated great efficiency in the attenuation of adverse effects such as heat islands. The thermal characterization of these systems are well studied, however few studies have been carried out on their acoustic potential. The characterization of the acoustic p...

Looking at the increasing request concerning sound insulation in building, TechnoFirst@ and Saint Gobain Vitrage propose an active double-glazing window. In this partnership, TechnoFirst@ brings its experience in active control system. The product will be characterized by a global insulation never obtained. It deals with an acoustic treatment of the air volume. Modelisations have been done and ...

Enhancing the sound insulation of glass interlayer film by introducing piezoelectric fibers.

Rigid polyurethane (PUR) foam is one of the most important insulating materials used today in the construction industry and is the main insulation material used in the global appliances industry. This study developed rice straw fiber-filled PUF (RPUF) and wheat straw fiber-filled PUF (WPUF) and explored the morphology, sound absorption properties, heat transfer, and compressive strength of the ...

When the studies about the effects of noise on the human health were investigated, it was determined that the noise has physiological, pathological, psychological and psycho-social results and affects sense organs, circulatory, respiration, digestion, excretory and nervous systems in terms of physiology. In this research, a sound insulation study was carried out in order to minimize the negativ...

The traffic spectra influence on indoor noise through windows is evaluated with laboratory and field measurements. Different traffic noise spectra were registered and reproduced, simulating the outdoor traffic conditions through different windows. Spectrum adaptation terms for the recorded spectra were different from the ones obtained from the Standards, showing that Normative gives a safe eval...
