  2. Architectural acoustics - Wikipedia

    en.wikipedia.org/wiki/Architectural_acoustics

    An anechoic chamber, using acoustic absorption to create a dead space. Interior building surfaces can be constructed of many different materials and finishes. Ideal acoustical panels are those without a face or finish material that interferes with the acoustical infill or substrate. Fabric covered panels are one way to heighten acoustical ...

  3. 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.

  4. List of building materials - Wikipedia

    en.wikipedia.org/wiki/List_of_building_materials

    This is a list of building materials. Many types of building materials are used in the construction industry to create buildings and structures . These categories of materials and products are used by architects and construction project managers to specify the materials and methods used for building projects .

  5. Absorption (acoustics) - Wikipedia

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

    In general, soft, pliable, or porous materials (like cloths) serve as good acoustic insulators - absorbing most sound, whereas dense, hard, impenetrable materials (such as metals) reflect most. How well a room absorbs sound is quantified by the effective absorption area of the walls, also named total absorption area.

  6. Acoustic plaster - Wikipedia

    en.wikipedia.org/wiki/Acoustic_plaster

    Some acoustic plasters contain aggregate, but better systems incorporate fiber. [2] Acoustic plasters are generally applied at a thickness between 1/16” and 1.5”. [3] Acoustic plasters consist of a base layer of absorptive substrate panels, which are typically mineral wool, or a non-combustible inorganic blow-glass granulate. [2]

  7. Sound transmission class - Wikipedia

    en.wikipedia.org/wiki/Sound_transmission_class

    When asked to rate their acoustical performance, people often describe these walls as "paper thin." They offer little in the way of privacy. Double stud partition walls are typically constructed with varying gypsum wallboard panel layers attached to both sides of double 2x4 wood studs spaced 16 inches on-center and separated by a 1-inch (25 mm ...
