초록

This study was designed to examine the effects of vocal loudness on Nasalance scores in Korean vowels. One normal adult without 'hypemasality' produced 3 types of vowels (/i/, /a/, /u/) in 3 levels of loudness (60, 70, 80dB). Nasalance scores (%) and oral & nasal energy intensity (dB) were measured through NasalView system. These data were compared among 3 levels of loudness and among 3 types of vowels. The results were as follow: For all vowels, Nasalance scores significantly reduced when vocal loudness increased. Because the increases of oral energy intensity were larger than that of nasal energy intensity. For all levels of loudness, Nasalance scores significantly differed among vowel types (/i/>/a/>/u/).
