2. Laminated glass - Wikipedia

   en.wikipedia.org/wiki/Laminated_glass

   Laminated glass is also used to increase the sound insulation rating of a window, because it significantly improves sound attenuation compared to monolithic glass panes of the same thickness. The interlayer is typically of polyvinyl butyral (PVB), ethylene-vinyl acetate (EVA), ionoplast polymers, cast in place (CIP) liquid resin, or ...

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. 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 ...

5. Polyvinyl butyral - Wikipedia

   en.wikipedia.org/wiki/Polyvinyl_butyral

   Polyvinyl butyral (or PVB) is a resin mostly used for applications that require strong binding, optical clarity, adhesion to many surfaces, toughness and flexibility. It is prepared from polyvinyl alcohol by reaction with butyraldehyde.

6. Vehicle glass - Wikipedia

   en.wikipedia.org/wiki/Vehicle_glass

   It is the piece of glass opposite the windshield. Back glass is made from tempered glass, also known as safety glass, and when broken shatters into small, round pieces. [1] Windshields are made of laminated glass, which consists of two layers of glass, separated by a vinyl sheet. [2] Vehicle glass may contain heating coils or antennae. [3]
