1. Why do you need a Screen- Excellence Acoustically Transparent screen? A code of best practice for Home Theater Installation

2. The first part of the question really is why an A.T. screen? All commercial theaters use it All sound to film studios use it for mixing When you see an actor speaking, you expect the sound to come from his or her mouth and from nowhere else The acoustic environment of a loudspeaker located very near to the floor or to the ceiling is disastrous The coherence between the sound and the image is essential at any time. When it travels across the screen, it becomes crucial: See next image

3. The image travels across the screen following a straight path, whereas you perceive the sound travelling down and then up. This reveals the incoherence

4. Here with an Acoustically Transparent screen the image and the sound remain in perfect coherence. This is the real cinematic experience This is clearly the best practice

6. Examples of best practice

7. Now the question remains: What kind of A.T. screen? Microperforated? The sound can only go through the holes punched in the screen material, representing about 6% of its surface. This means 94% of the sound is reflected backwards

8. Here is the result: The red trace is the response of the speaker alone. The black trace is through a microperforated screen

9. Woven ? The sound diffracts around the woven threads to make its way through the screen surface. This generates a bit of loss by absorbing some energy, but no sound is reflected backwards.

10. And here is the result: This is the obvious choice if you are seeking the best result

11. Now, what screen material will you pick? Best competition Enlightor 4K Enlightor Neo WEnlightor Neo S

12. Knowing what is at stake… Moiré does not necessarily occur with microperforated screens or with other woven screens in HD. Simply, it can… Enlightor 4K is 100% immune to moiré effect

13. If you want to follow the path of best practice, you are left with no alternative
