Set layer opacity to 50% and blending mode to soft light. Now select your background layer and add some noise by going to "filter > Distort > noise".
Now merge both layers together, and goto "filter > render > lighting effects" use the settings below. (sorry about quality of image)
Now select the rounded rectangle tool and make these 3 set of boxes.
Once you have made the boxes set the all the layers opacity to 40% and add these layer styles.
