    The clouds are between 4 and 8 inches (100 and 200 mm) thick, [15] and in total there are 31 panels: [2] 22 on the ceiling, 5 on the right side wall and 4 on the left side wall. [9] [7] To position the clouds, 3 ⁄ 8 inch (9 + 1 ⁄ 2 mm) metal cables suspend them from the ceiling of the room, giving them the necessary inclination and height ...

    en.wikipedia.org/wiki/Sound_baffle

    An important type of sound baffle is the noise barrier constructed along highways to reduce sound levels in the vicinity of properties. Sound baffles are also applied to walls and ceilings in building interiors to absorb sound energy and thus lessen reverberation. [1]

  4. Acoustic panel - Wikipedia

    en.wikipedia.org/wiki/Acoustic_panel

    An acoustic board is a board made from sound absorbing materials, designed to provide sound insulation. [3] [4] Between two outer walls sound absorbing material is inserted and the wall is porous. Thus, when sound passes through an acoustic board, the intensity of sound is decreased. The loss of sound energy is balanced by producing heat energy.

    The typical sound paths are ceilings, room partitions, acoustic ceiling panels (such as wood dropped ceiling panels), doors, windows, flanking, ducting and other penetrations. Technical solutions depend on the source of the noise and the path of acoustic transmission , for example noise by steps or noise by (air, water) flow vibrations.

  6. Noise control - Wikipedia

    en.wikipedia.org/wiki/Noise_control

    Acoustical wall and ceiling panels are a common commercial and residential solution for noise control in already-constructed buildings. Acoustic panels may be constructed of a variety of materials, though commercial acoustic applications will frequently be composed of fiberglass or mineral wool-based acoustic substrates.

    May 2017) (Learn how and when to remove this message) An example of a material in which absorption can observed: sound absorbing foam, also known as acoustic foam . In acoustics , absorption refers to the process by which a material, structure, or object takes in sound energy when sound waves are encountered, as opposed to reflecting the energy.
