AB  - After decades of extensive investigation, the international broadcasting community, represented by technical associations and bodies, has set precise standards aimed to objectively assess loudness levels of programs. Although all standards rely on the same algorithm as described in ITU-R BS1770, there are still two possible ways to implement such metering, including voice detection and gating. These two different implementations might, in some cases, provide measurements that significantly differ from each other. Furthermore, while the gating feature is uniquely defined in the updated version of BS1770-3, voice detection is not currently specified in any standard and its implementation is the independent choice of manufacturers. This paper analyses this scenario by comparing the results and robustness provided by three different loudness meters based on voice detection. In addition, those values are compared with measurements obtained by using BS1770-3 compliant loudness meters, including tables, comments, and conclusions.
