Vocal Loudness Variation With Spectral Slope

Abstract: Objective This investigation addresses the loudness variations in sones achievable with spectral slope variations (higher harmonic energy) in human vocalization and compares it to the sound pressure level (SPL) variations typically reported in the voice range profile (VRP). Method The primary methodology was computational. The ISO standard 226 was used to convert SPL values to sones for a 125- to 1000-Hz range of fundamental frequency and a –3 dB/octave… Show more

“…Computation of loudness in sones from a sound spectrum followed a previous publication. 4 A script published by Tackett was used to convert SPL to loudness level in phons and then to loudness in sones in the range of 10−90 phons. 12 Equations are given in the earlier publication and are reproduced here in the Appendix.…”
