Acoustic ceilings are the ceiling systems that absorb sound waves to the surface and accordingly prevent negative echoes. Working principle of the ceilings with such features is based on the rule concerning the change of the energy form transmitted by sound waves hitting the surface. Sound energy to the ceiling turns into heat energy because the surface is rough and soft, and the echo power of severity-reducing sound waves decreases. Ceilings with these features are called porous or perforated acoustic ceilings. Another way to provide acoustic properties on the ceiling is to take advantage of flexible surfaces. Part of the sound energy to the elastic surface turns into motion energy by flickering the surface, and the ability to make undesired echoes is reduced. Ceilings with these features are also called vibrating acoustic ceilings. The spaces between the elements should be indented as well as the surfaces should be arranged at different positions and angles. As a ceiling covering element, perforated plaster plates, space-positioned profile wood elements, mineral fibre plates, perforated chipboard and similar equipment are used. The plates can also be coated with fabrics and similar materials. The total area of the holes on acoustic plates with high levels of sound waves that can also absorb the high levels of sound waves should not be less than 15% of the plate surface. One way to increase acoustic properties is to place plates made of rockwool, isogamy and similar materials under the covering element.
- It is at 12.5 mm size mounted on the framework of metal ceilings and is furnished with plaster so as to add robustness to the ceiling.
- It is easy to assemble and can be completed in a short time.
- Acoustic suspended ceiling is quite stylish and has an aesthetic appearance.
- It prevents sound echoes thanks to its acoustic structure
*These are long-lasting structures that are fire and water resistant.
