"The spatial attribute envelopment has long been considered an important 
property of excellent concert hall acoustics. In the past, research in this 
area has produced the definition listener envelopment (LEV) and several 
equations designed to predict it.

However with the recent development of multichannel audio systems capable 
of positioning sound sources all around the listener, it is apparent that 
the attribute is not so easily defined and that a more appropriate 
definition may be needed. This poster introduces a definition of 
envelopment more appropriate for multichannel audio and outlines a recent 
pilot experiment conducted by the authors."
