  2. 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.

  3. Soundproofing - Wikipedia

    en.wikipedia.org/wiki/Soundproofing

    A pair of headphones being tested inside an anechoic chamber for soundproofing. Soundproofing is any means of impeding sound propagation.There are several methods employed including increasing the distance between the source and receiver, decoupling, using noise barriers to reflect or absorb the energy of the sound waves, using damping structures such as sound baffles for absorption, or using ...

    en.wikipedia.org/wiki/Anechoic_tile

    A close-up view of an Alberich tile, illustrating patterns of multiple holes with different diameters. The technology of anechoic tiles was developed by the Kriegsmarine during the Second World War, codenamed Alberich after the invisible guardian dwarf of the Rhinegold treasure from Richard Wagner's Der Ring des Nibelungen music dramas.

  5. Absorption (acoustics) - Wikipedia

    en.wikipedia.org/wiki/Absorption_(acoustics)

    An acoustic anechoic chamber is a room designed to absorb as much sound as possible. The walls consist of a number of baffles with highly absorptive material arranged in such a way that the fraction of sound they do reflect is directed towards another baffle instead of back into the room.

  6. Acoustic plaster - Wikipedia

    en.wikipedia.org/wiki/Acoustic_plaster

    Although acoustic panels are common in basements or recreational areas, they are seldom used in living spaces due to aesthetic reasons. Instead, conventional plaster or drywall systems were more frequently used in homes and other environments where interior aesthetics is a more important consideration but these are, however, not ideal in sound ...

  7. Architectural acoustics - Wikipedia

    en.wikipedia.org/wiki/Architectural_acoustics

    Architectural acoustics (also known as building acoustics) is the science and engineering of achieving a good sound within a building and is a branch of acoustical engineering. [1] The first application of modern scientific methods to architectural acoustics was carried out by the American physicist Wallace Sabine in the Fogg Museum lecture room.
