4.2kg Polyester Fiber Sound Acoustic Panel / Soundproof Panels For Walls

1.22*2.44m 4.2kg Polyester Fiber Acoustic Interior Wall Panelings

Description

Main Characteristic

• With fiberglass substrate, multiple colours fabric cover the face;
• Class A fire-resistanton the combustion;
• Acoustical inner core absorbs 50-90% of sound striking the surface, help silence a space;
• Highly effective sound absorption (NRC 0.95) requires fewer absorbers to treat your space;
• 3 to 6 times the sound absorption of fabric-covered fiberglass;
• Enhance acoustics with wall panels available in multiple sizes, shapes, and colors,custom colors available.

Acoustic absorption is usually defined in terms of an absorption coefficient(usually denoted by the Greek letter alpha,,

defined as the ratio of absorbed to incident sound energy from a single interaction between a sound wave and a certain material.

Absorption coefficients range from 0 to 1 and vary with frequency,

means that the material absorbs no sound and reflects all sound energy incident on it.

means that the material absorbs all sound energy incident on it and reflects none.

Absorption coefficients of 0 and 1 are ideal values that do not exist in reality because all materials reflect and absorb some sound.

In general, materials having absorption coefficients less than 0.15 are considered to be reflective and those having absorption coefficients greater than 0.4 are considered to be absorptive.As you can see our Testing report show that our products have a very good performance in a large range of application.

Applications:Stadium ,auditorium, multifunction room ,studio and any other places where seek for high acoustic requirement
