In constructing a residential building located in the city of Milan we designed several new kinds of vertical and horizontal partition walls in the way to achieve the prescribed values of sound insulation for specific residential use according the Italian new Regulations. In order to investigate the...

The study on the noise reduction using double wall enclosure technique has put great emphasis on the characteristics of low frequencies noise reduction which are commonly generated by compressors or diesel engines. Three types of materials were used in the construction of the enclosures : plywood, ac...
Most domestic walls rate somewhere in the middle from about 30–45. You can improve the STC of a partition wall by building it from a more dense material (sound insulation improves by about 5 decibels for every doubling of mass), by adding an air gap, or by adding sound absorbing ...
摘要: Reports that Kutztown University in Pennsylvania applied International Cellulose's K-13 spray-on acoustic and thermal insulation to the ceiling of its field house. Reduction of the reverberation time from 4.2 seconds to 1.92 seconds; Enhancement of the lighting system and increased visibility....

Measures such as noise barriers along highways or railways, earth berms, gabions, and use of acoustic insulation materials and architectural features in buildings can break the chain of noise propagation. Mitigation at source Noise mitigation measures differ in effectiveness. Emission reduction at source...

Our PET slatted wood acoustic panels can be used to create slatted walls and ceilings, which are suitable for a variety of scenes, such as studios, home theater, music halls, schools, offices, KTV and other places where sound insulation and modern decoration styles...
It has been demonstrated that a staggered window achieves better noise reduction performance than a traditional single glazing one at middle to high frequencies while maintaining a degree of natural ventilation. There is, however, little improvement in t
