In the structure of these wall coverings, special materials have been used that can absorb sound waves well. however, the body of these wall coverings reflects sound and sound waves do not pass through them, thus keeping the sound in the environment. In this way, acoustic tile can also improve the quality of sound produced in the building. Acoustic tiles can be made in a variety of designs, therefore, they can be used in offices, commercial, medical, educational, conference rooms and halls, universities, cinemas and music halls, and for concerts and conferences and residential units. One of the disadvantages of acoustic wall coverings is that they are difficult to clean and clean.
