Relation between voice sound pressure and subglottal pressure as a diagnostic cue. | Voice sound pressure and esophageal pressure amplitudes are measured for 120 subjects with and without laryngeal status. The esophageal pressure amplitudes are taken as a approximation of the subglottal pressure. The dependency of sound pressure on subglottal pressure is approximated by a nonlinear function. The slope ... | 549,563 | [
