  2. 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 ...

  3. Cellulose insulation - Wikipedia

    en.wikipedia.org/wiki/Cellulose_insulation

    Insulation reduces sound travelling through walls and between floor levels. Cellulose provides mass and damping. This reduces noise in two ways: it reduces the lateral vibration of sheetrock and attenuates the passage of sound along cavities. Cellulose is approximately three times denser than fiberglass, providing a slight improvement in sound ...

  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.

  5. Sound transmission class - Wikipedia

    en.wikipedia.org/wiki/Sound_transmission_class

    The STC or sound transmission class is a single number method of rating how well wall partitions reduce sound transmission. [3] The STC provides a standardized way to compare products such as doors and windows made by competing manufacturers. A higher number indicates more effective sound insulation than a lower number.

  7. Underlay - Wikipedia

    en.wikipedia.org/wiki/Underlay

    Underlay for timber floors is typically 3mm closed cell plastic foam. This primarily provides sound insulation and a vapour barrier. A watertight vapour barrier should only be used though, when neither condensation from humid air coming from beneath nor water spillage coming from above are to be expected. Especially if there is spillage it will ...
