By mounting sound-absorbing plates (acoustic panels / panels), you can reduce reverberation time, thereby reducing the effect of sound reflections in a given frequency range in rooms with poor acoustics, at worst, directly as echoes . The reverberation time is the time it takes for the sound to appear in space, and precisely the reverberation time is a very important factor in how we perceive sound quality where the sound comes from and not least speech understanding and must not be too big.
• Hard and smooth surfaces give a long reverberation time and therefore give echoes and shrill acoustics. Ie materials such as concrete, brick, paved plaster walls and ceilings, wooden floors, etc.
• Soft and porous materials (absorbents) provide low reverberation time, and thus more sound-dead rooms.
