It is now well understood that listener envelopment (LEV) is an essential component of good concert hall acoustics. An objective measure based on the late-lateral energy has been shown to perform well at predicting LEV. One goal of multichannel surround systems is to improve the re-creation of the concert hall experience in a home listening environment. By varying the amount of late-lateral energy, such systems should allow the perception of LEV to be enhanced and controlled. In this paper the loudspeaker/listening room interactions are shown to limit the range of acoustical conditions that can be re-created. A series of formal subjective tests were conducted to determine if objective measures of late-lateral energy are suitable for predicting LEV in multichannel surround systems.
