The Relationship Between Nasal Sound Pressure Level and Palatopharyngeal Closure A group of 21 subjects with well-fitted speech bulbs was compared for nasal sound pressure level (SPL) with a group of 13 subjects having moderate deficiency of palatopharyngeal closure. The difference in mean measures for the two groups was statistically significant. Correlation coefficients are reported for the relationships between nasal ... Research Article

A group of 21 subjects with well-fitted speech bulbs was compared for nasal sound pressure level (SPL) with a group of 13 subjects having moderate deficiency of palatopharyngeal closure. The difference in mean measures for the two groups was statistically significant. Correlation coefficients are reported for the relationships between nasal SPL and both a cinefluorographic measure of palatopharyngeal closure and several articulation measures.
