Abstract
Representations of a subject's minimum vocal intensities (SPLmin)at selected levels of pitch range are called, Fo-SPLmin Profiles. Such displays potentially are an indirect means of documenting a person's change in laryngeal function and status. The potentiality is limited by insufficient evidence that subjects' performances are replicable on repeated testing. As a pilot study, four normal adults produced their SPLmin at 1/3 octave increments of pitch range on three occasions over a 2-week period. It appears that Fo-SPLmin Profiles are replicable. The magnitudes of SPLmin seem to correlate with increments of pitch range at which subjects phonated and increase at a rate of 8 to 12 dB/octave starting around 65 dB (3.8 cm from the lips).This publication has 1 reference indexed in Scilit:
