DESCRIPTION:Direct View Displays bring high image quality in the cinema but
  suffer from lack of cohesion with front channel sound which is\, in theor
 y\, supposed to come from the same location as the picture. At this stage\
 , the main speakers are typically placed above the direct view display and
  the sound coming from them doesn’t perfectly match with the picture. Afte
 r all\, the dedicated speakers are still called “screen channels”.\nCinema
  projection systems are much better in that regard because of the speakers
 ’ traditional placement behind the screen. However\, audio quality is comp
 romised because of the perforated screen which could be considered as an o
 bstacle letting only pass a given portion of the sound. Some of the conseq
 uences are well known: Comb filtering effect\, lack of intelligibility\, p
 oor auditorium coverage.\nWith the advent of objet based soundtracks in ci
 nema\, the difference in terms of quality between the sound coming from th
 e screen channels and the surround speakers has become even more obvious t
 hough compromises in sound quality have never been fully quantified since 
 perforated screens had always been needed for cinema audio until very rece
 ntly. Now that high quality cinema audio system are available which are no
 t requiring perforated screens\, it appears necessary to quantify these ef
 fects.\nIn this article\, we are evaluating the auditorium sound coverage 
 by taking frequency measurements at different locations of a movie theater
  (center\, sides and corners) for sound coming from the typical 3 screen c
 hannels through a traditional perforated screen\, then with new technology
  emitting sound in front of the screen. The purpose of those measurements 
 is to demonstrate that even members of the audience not seated inside the 
 usual “sweet spot” area can enjoy the sound mix\, including information co
 ming from speakers located at the opposite side of the room\, in addition 
 to better sound transitions from the screen channels to the surround chann
 els.
