Upplevd kvalitet kopllat till dynamik och hörstyrka i inspelad musik

Sammanfattning

Prior research has shown that music that are more limited in the dynamic range are perceived to have lowerquality than music that are less limited. In this study quality perception connected to the use of limitation andaudio level in recorded music is examined. This was done by limiting one track by different amounts tomatch the PLR of the track with a mean PLR of music from before the loudness war started and the meanPLR of music from 2022. After that the limited tracks was loudness normalized and then new tracks werecreated from the two most limited tracks. These were gained up by 1 and 2 dB. Totally 7 different trackswere created. 20 Audio engineering students were asked to listen to 9 different comparisons between thetracks and evaluate the perceived quality of the tracks. As a result, there were no significant qualitydifference found between the tracks that haven’t been gained up. However, the stimulus that had a louderlevel were perceived to have significantly higher quality than the quieter stimulus.
