  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 ...

  4. Acoustic foam - Wikipedia

    en.wikipedia.org/wiki/Acoustic_foam

    Acoustic foam tiles are suited to placing on sonically reflective surfaces to act as sound absorbers, thus enhancing or changing the sound properties of a room. [11] This type of sound absorption is different from soundproofing, which is typically used to keep sound from escaping or entering a room rather than changing the properties of sound ...

    Scott Warrick of Bloomington, Ind. has a noise problem outside his house: jackhammers. "I'm enduring three months of daily jackhammering as they tear down a local school." Excessive noise entering ...

  6. Sound transmission class - Wikipedia

    en.wikipedia.org/wiki/Sound_transmission_class

    The table below illustrates sound proofing test results from a wall partition that has a theoretical maximum loss of 40 dB from one room to the next and a partition area of 10 meters squared. Even small open gaps and holes in the partition have a disproportionate reduction in sound proofing.

  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.
