The phonation threshold pressure (PIP) has been found to increase during vocal fatigue. In the present study we compare PTP and collision threshold pressure (CTP) before and after vocal loading in singer and non-singer voices. Seven subjects repeated the vowel sequence /a,c,i,o,u/ at an SPL of at least 80 dB @ 0.3 m for 20 min. Before and after this loading the subjects' voices were recorded while they produced a diminuendo repeating the syllable /pa/. Oral pressure during the /p/ occlusion was used as a measure of subglottal pressure. Both CTP and PIP increased significantly after the vocal loading.
