While the LUFS standard was originally developed for broadcast applications, it offers a convenient means of calibrating program material stimuli to an equal loudness level, while remaining in a multichannel format. However, this calibration is based on an absolute sound pressure level of 60 dBA, the preferred listening level when watching television. Levels used in analytical listening and perceptual experiments tend to be significantly higher. This disparity may affect the accuracy of the Leq(RLB) weighting filter employed in LUFS meters. To address this issue, the development of the LUFS standard is examined to assess its suitability for the task. The findings suggest that a compromise between analytical listening and loudness matching in perceptual experiments requires careful consideration of experimental variables.
