2. 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.

3. Soundproofing - Wikipedia

   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. Impact insulation class - Wikipedia

   en.wikipedia.org/wiki/Impact_insulation_class

   Impact insulation class (or IIC) is an integer-number rating of how well a building floor attenuates impact sounds, such as footsteps. A larger number means more attenuation. The scale, like the decibel scale for sound, is logarithmic. The IIC is derived from ASTM method E989, which in turn uses a tapping machine specified in ASTM method E492. [1]

5. 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 ...

6. 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.
