   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. 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 ...

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.

7. 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 ...
