  2. Acoustic quieting - Wikipedia

    en.wikipedia.org/wiki/Acoustic_quieting

    Sound isolation: Noise isolation is isolating noise to prevent it from transferring out of one area, using barriers like deadening materials to trap sound and vibrational energy. Example: In home and office construction, many builders place sound-control barriers (such as fiberglass batting ) in walls to deaden the transmission of noise through ...

  3. Pipe insulation - Wikipedia

    en.wikipedia.org/wiki/Pipe_insulation

    Pipe insulation cannot prevent the freezing of standing water in pipework, but it can increase the time required for freezing to occur—thereby reducing the risk of the water in the pipes freezing. For this reason, it is recommended to insulate pipework at risk of freezing, and local water-supply regulations may require pipe insulation be ...

  4. 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 ...

  6. Absorption (acoustics) - Wikipedia

    en.wikipedia.org/wiki/Absorption_(acoustics)

    When sound from a loudspeaker collides with the walls of a room, part of the sound's energy is reflected back into the room, part is transmitted through the walls, and part is absorbed into the walls. Just as the acoustic energy was transmitted through the air as pressure differentials (or deformations), the acoustic energy travels through the ...

  7. 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.

  8. Building insulation material - Wikipedia

    en.wikipedia.org/wiki/Building_insulation_material

    Insulation is a barrier material to resist/reduce substance (water, vapor, etc. ) /energy (sound, heat, electric, etc.) to transfer from one side to another. Heat/ Thermal Insulation is a barrier material to resist / block / reflect the heat energy (either one or more of the Conduction, Convection or Radiation) to transfer from one side to another.

  9. Noise control - Wikipedia

    en.wikipedia.org/wiki/Noise_control

    Common sound absorption materials include decoupled lead-based tiles, open cell foams and fiberglass; Vibration damping: applicable for large vibrating surfaces. The damping mechanism works by extracting the vibration energy from the thin sheet and dissipating it as heat. A common material is sound deadened steel.
