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. Micro perforated plate - Wikipedia

   en.wikipedia.org/wiki/Micro_perforated_plate

   The goal of a sound absorber is to convert acoustical energy into heat. In a traditional absorber, the sound wave propagates into the absorber.

   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 ...
