Popcorn ceiling texture. A popcorn ceiling, also known as a stipple ceiling or acoustic ceiling, is a ceiling with one of a variety of spray-on or paint-on treatments. [1] The bumpy surface is created by tiny particles of vermiculite or polystyrene, which gives the ceiling sound-deadening properties. Mixtures are available in fine, medium, and ...
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.
A dropped ceiling is a secondary ceiling, hung below the main (structural) ceiling. It may also be referred to as a drop ceiling, T-bar ceiling, false ceiling, suspended ceiling, grid ceiling, drop in ceiling, drop out ceiling, or ceiling tiles and is a staple of modern construction and architecture in both residential and commercial applications.
In the 1980s, over a period of 3 years DAMPA developed, in collaboration with Freudenberg, a new acoustic felt (Soundtex) to replace mineral wool. The new felt revolutionized the ceiling industry, and DAMPA was awarded the Danish Environmental Prize. [4] In the 1990s, a new design concept with acoustic felt in various colours was developed.

After corkboard, the logical move was to fiberboard, and then to ceiling board. Cork tile and linoleum led to vinyl flooring, then ceramic tile , laminate flooring , and carpeting . In 1917, Armstrong Cork signed with the Batton Company advertising agency, a relationship that continues to this day through their corporate descendants.
Acoustic levitation is a method for suspending matter in air against gravity using acoustic radiation pressure from high intensity sound waves. [1] [2] It works on the same principles as acoustic tweezers by harnessing acoustic radiation forces. However acoustic tweezers are generally small scale devices which operate in a fluid medium and are ...
[6] [10] The artwork comprises 31 clouds, with 22 on the ceiling, five on the right side wall and four on the left side wall. [9] [11] [12] The largest of these has a surface area of 80 m 2 (860 sq ft) and a weight of approximately 2.3 tonnes (2.5 short tons). [9] Ladders exist in the ceiling space, allowing people to climb through the clouds. [7]
