The aim of this study was to obtain normative nasalance scores for adult and children subjects speaking Turkish language and obtain a reference for normality when nasality is evaluated.


Mean nasalance scores were obtained from 35 normal-speaking children aged 7 to 13 years, and 125 adults aged 18 to 69 years during the repetition of 3 nasalance passages that were categorized according to the amount of nasal consonants (oral, oronasal, and nasal passages). The Nasometer (model 6400) was used to obtain nasalance scores for the 3 reading passages.


Group mean ± SD nasalance scores of children for oral passage, oronasal passage, and nasal passage were 15.14 ± 4.81, 37.76 ± 4.42, and 49.23 ± 6.95, respectively. Nasalance scores for the adult group were 13.46 ± 6.26, 37.84 ± 6.13, and 50.28 ± 7.77, respectively. There were significant differences in mean nasalance scores for oral versus nasal materials both for children and adult groups.


The present study provides normative nasalance scores for Turkish-speaking children and adults. The results indicated acceptable differentiation between oral and nasal materials.
