Acoustic transparency projection screen film has the ability of the screen to allow sound to pass through with little interference, this material bring the performance of high-end theater performance into the private home cinemas. The value of an “acoustic projector screen” is in its ability present a reference quality projected image over in-wall speakers., such as cinemas, home theaters and auditoriums. Duletai accomplish this by perforating the fabric with small holes in matrix that are barely noticeable at a distance. DuraScreen DLT-2023 is made of a very strong pvc material with thousands of very small perforated holes in it. (Perforated means to pierce and make a hole or holes in). Essentially there’s a ridiculous amount of holes poked in the material which allows sound to pass through the screen. The material is typically made of a very strong PVC with holes that are usually less than 3mm in diameter.
Perforation or microperforation is typically used to help alleviate acoustic pressure through a projection screen, particularly middle to high range frequencies. Standard perforation is 57,000 holes/m² (37 holes/in²) with an open area of approximately 7%; microperforation is 300,000 holes/m² (195 holes/in²) with an open area of approximately 6%.
