- The vast loudness span of broadcast sound can be reduced by the use of loudness meters. In an ideal case, the measured and the perceived loudness would be equal. A loudness meter fulfilling the EBU R-128 recommendation was investigated for its correspondence with perceived loudness. Several sound stimuli with large loudness differences representing five different types of broadcast program material were normalized to have equal meter measured loudness level. Subjects listened to pairwise presentations of the normalized stimuli, which they subsequently set to have equal perceived loudness. The settings were recorded and analyzed. The results show that the normalization yields both equal as well as different perceived loudness between program types. The maximum difference was ±2.8 dB.
