Sound absorbing plates are designed to absorb sound reflections in specific frequency ranges, which may be too dominant, and provide better acoustics.
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.
Which materials and surfaces affect the acoustics?
• 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.
