Objective Measures of Listener Envelopment in Multichannel Surround Systems
A common goal in multichannel musical recordings is to create a better approximation of the concert hall experience than can be achieved with a traditional stereo reproduction system. Listener envelopment (LEV) is known to be an important part of good concert hall acoustics and is therefore desirable in multichannel reproduction. A series of subjective tests were conducted to determine which acoustic parameters are important to the creation of LEV in multichannel surround systems. New frequency-dependent objective measures of LEV were derived and their ability to predict the subjective results was evaluated.
