1) NOISE BARRIER BLANKETS 

Noise blankets or noise barrier blankets are hung from walls like a curtain or fixed to floor mounted steel frames to shield or enclose noise generating equipment from receivers.Frequently also referred to as acoustic blankets or sound blankets they are manufactured from synthetic mesh fabric therefore water resistant, It is light weight and factory tested for noise reduction of between 20 to 40 dBA. It is Ultraviolet (UV) resistant.

There are two types of noise blankets whereas a noise barrier blanket is a noise blocker with higher transmission loss the other type is a noise absorber with higher noise absorption ability. Both these noise blankets are manufactured from different fabric with similar acoustic insulation. The use of either one of these noise blankets depend on the situation and both are made from different types of fabric. These acoustic sound blanket contain a noise mineral glass wool absorbent encapsulated in the synthetic mesh fabric.  


2) TEMPORARY NOISE BARRIER WALL FOR CONSTRUCTION SITES 

FRONT VIEW BACK VIEW CLAMPSCLOSE UP VIEW

Construction site noise are generated by equipment such as piling, hacking, drilling punching and excavation machine. In city or towns such development may cause discomfort to residents of neighboring property. Contractors may propose installation of temporary metal noise barriers to mitigate such noise pollution. The front face with louvers will faces the construction site for noise absorption. These noise panels for construction sites are 3 meters in length and 500 mm in width. It is easily installed vertically on hoarding structures. It can be a temporary noise barrier wall at site of heights from 3 meters. These noise barrier panels can be installed and dismantled easily. Each panel is light weight (<18kg) and slide into a track attached to tubular frames such as scaffolding or other independent steel frames. Installation diagrams or additional info dial 6012-208 8228

3) HIGHWAY NOISE BARRIER WALLS

Noise Barriers are common features along Malaysian highways and expressways. These noise barriers walls are either Metal Absorption type or Masonry Acoustic type and ... Metal type noise barrier being lightweight and higher in sound absorption are preferred for elevated highways, bridges, MRT of LRT structures.

5) TYPES OF MATERIAL SUITABLE FOR THE CONSTRUCTION OF A NOISE BARRIER WALL - Metal, Masonry, Concrete, Timber, Earth etc

6) WHAT IS NOISE?  Noise is unwanted sound....Continuous exposure to loud noise will lead to noise related deafness.  

7) ARE THESE NOISE BARRIERS WALLS EFFECTIVE IN NOISE REDUCTION? Besides selecting the MOST SUITABLE MATERIAL the height and the length of a noise barrier wall are IMPORTANT PARAMETERS to consider.
