Description:
Sound insulation fabric panels has excellent effect on sound
absorbing with a wide spectrum of acoustic absorption coefficient
among low, medium and high frequency. It can achieve the greatest
possibility of customer's requirement.
It usually used for the public area.Such as the
cinema,studio,meeting room,KTV,karaoke and other place.If you have
a cinema project,the Fabric panel for walls is the best choice.
Feature:
1.It has good decoration, easy to install and no dust proof etc.
various advantages.
2.We have 2 types for your choose,the fabric or Pu leather.
3.Environmental protection, fire retardant, wide range sound
frequency absorption etc.
Acoustic details:
Acoustic absorption is usually defined in terms of an absorption
coefficient(usually denoted by the
Greek letter alpha, α), 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,
α=0 means that the material absorbs no sound and reflects all sound
energy incident on it.
α=1 means that the material absorbs all sound energy incident on it
and reflects none.
Absorption coefficients of 0 and 1are 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
