2. Absorption (acoustics) - Wikipedia

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

   How well a room absorbs sound is quantified by the effective absorption area of the walls, also named total absorption area. This is calculated using its dimensions and the absorption coefficients of the walls. [4] The total absorption is expressed in Sabins and is useful in, for instance, determining the reverberation time of auditoria.

3. Acoustic quieting - Wikipedia

   en.wikipedia.org/wiki/Acoustic_quieting

   Sound reflections: by limiting the reflection using many methods, e.g. by using acoustic absorption (deadening) materials, trapping the sound, opening a "window" to let sound out, etc. By analyzing the entire sequence of events, from the source to the observer, an acoustic engineer can provide many ways to quieten the machine.

4. Acoustical engineering - Wikipedia

   en.wikipedia.org/wiki/Acoustical_engineering

   Absorption is the loss of energy that occurs when a sound wave reflects off of a surface, and refers to both the sound energy transmitted through and dissipated by the surface material. [26] Reverberation is the persistence of sound caused by repeated boundary reflections after the source of the sound stops.

   Favoring fuller textile expressions over roller blinds, Loya adds that, in addition to framing a space and absorbing sound, drapery completes a room, making it feel more tailored.

6. 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 ...

7. Noise control - Wikipedia

   en.wikipedia.org/wiki/Noise_control

   Sound absorption: a porous material which acts as a ‘noise sponge’ by converting the sound energy into heat within the material. 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 ...
