Investigations on the Inclusion of the LFE Channel in the ITU-R BS.1770-1 Loudness Algorithm
The current ITU-R BS.1770-1 loudness algorithm does not include the LFE channel for 5.1-channel audio signals. It has been proposed that the LFE channel should be included in the loudness measurement to improve measurement accuracy and to fully reflect all the channels of a 5.1 audio signal. On the other hand the exclusion of the LFE channel in most downmixing systems may be one reason not to include it in the loudness measurement. Along with looking at objective pros and cons of adding the LFE channel to the BS.1770-1 loudness algorithm, results of formal subjective tests are used to show the effect of the LFE channel on perceived loudness of multichannel programme material.
