“…Like in our present findings, no significant difference between genders for the two stimuli were found. The same has been observed by several other authors (16)(17)(18)(19) . This result may be related to the fact that fundamental frequency of girls and boys are similar until puberty (29) .…”

“…The use of nasometry in different countries soon has shown that nasalance varies according to the language spoken (9)(10)(11)(12)(13) . Studies with Brazilian Portuguese speakers, including children, have shown that nasalance can also vary according to age, gender or the type of emission (syllables and/or sentences) (14,15) , confirming observations for other languages (13,(16)(17)(18)(19)(20)(21)(22) .…”

“…It is considered an indirect method because it does not allow visualizing velopharyngeal structures (2) . Yet, it is a valuable tool to assess hypernasality, especially in children, as they can show an uncooperative behavior during the perceptual assessment (18) .…”

RESUMO Objetivo Determinar valores de nasalância de crianças falantes do Português Brasileiro sem alterações na produção da fala, atraso de linguagem e deformidades dentofaciais evidentes, aos 5 anos de idade, e verificar as diferenças entre tipos de emissão e entre gêneros. Método A nasalância foi determinada em 20 crianças, 11 do gênero masculino e idade entre 4 anos e 10 meses e 5 anos e 11 meses, utilizando um nasômetro II 6450 (KayPENTAX), na produção de oito sílabas tipo consoante-vogal e uma sequência de nove vocábulos. A significância das diferenças entre os tipos de emissões foi verificada pelo Teste de Tukey e, entre os gêneros, pelo teste de Mann-Whitney, para um nível de 5%. Resultados Os valores médios de nasalância foram os seguintes: /pa/= 10±4%, /pi/= 22±7%, /sa/= 11±5%, /si/= 24±11%, /ma/= 57±11%, /mi/= 73±13%, /la/= 14±9%, /li/= 25±11%, vocábulos (pipa, bis, burro, tatu, pilha, cuca, gui, fila, luz)= 20±6%. Na maioria das comparações, os valores de nasalância das sílabas nasais foram significantemente maiores do que os das sílabas orais (com vogal alta ou neutra) e os valores das sílabas orais com vogal alta foram significativamente maiores que os das sílabas orais com vogal neutra. Não houve diferença significante entre os gêneros. Conclusão Foram definidos valores normais de nasalância de crianças falantes do Português Brasileiro, de 5 anos de idade, sendo que a metodologia empregada pode servir de padrão para o diagnóstico precoce de desvios de nasalidade, como a hipernasalidade observada na fala de crianças com fissura palatina.

“…In the literature, a controversy exists about the differences in nasalance values, obtained by the Nasometer [4], for age and gender (table 1). Some authors report low correlations between age and nasalance [10,11,16,17,18,19,20], while others mention significantly lower nasalance values in younger children compared with older children for nasal sentences [21,22] and oral texts [22], or lower nasalance scores for certain speech stimuli in children compared with adults [23,24,25,26]. Possible explanations for these differences are the stronger evidence of coarticulation in adult speakers as a result of speaking experience [27], age-related changes in lymphoid and gland tissue at the velopharyngeal port [28], and the growth of the oropharynx [29] and nasal cavity [30].…”

Objective: Since resonance disorders have a multidimensional nature and occur in several craniofacial pathologies, the aim of the present study was to determine the influence of age and gender in normal-speaking children without resonance disorders on an objective multiparametric index of hypernasality. Patients and Methods: A total of 74 Flemish children (37 boys and 37 girls), aged 4-12 years, without resonance disorders were included. A Nasometer was used to obtain nasalance scores (1 phoneme, 2 reading passages). An aerodynamic value was calculated using maximum duration time, and the mirror-fogging test by Glatzel was applied to visualize nasality as measured by condensation. With the obtained results, a ‘Nasality Severity Index' (NSI) was calculated. Results: A significant age effect was found, in which the NSI increased with increasing age (p < 0.001). No significant difference for the NSI was detected concerning gender (p > 0.05). Unfortunately, considerable standard deviations from the mean NSI were found. Conclusion: Although a multiparametric index can form a more powerful approach in the assessment of and treatment planning for individuals with hypernasality, the present study revealed large interindividual differences in the current NSI. Therefore, adaptation of the current NSI is recommended, by which the influences of personal and environmental variables are taken into account.

“…have been conducted to evaluate nasalization norms amount, especially in children using Nasal view software and sometimes Nasometer. These studies, albeit confirming significant differences in nasalization scores in different languages and accents, have to interpret separately [19][20][21][22]. According to the results of studies and statistical analysis, Nasometer is suitable for evaluating resonance disorders.…”

Determining Normative Nasalization Scores Among Persian-speaking Adults

Introduction: Awareness of the nasality norm condition in normal people's speech (children and adults) is very important for assessment and treatment of nasality disorders. The main goal of this study was to determine normative nasalance scores among Persian-speaking adults. Material and Methods:In this descriptive-analytical cross-sectional study, nasalance value of 152 adults (54 males and 98 females) older than 18 years was examined by access method. Nasality test which included vowels (front/back, high/low), syllables (with oral and nasal consonants), words (with oral and nasal consonants), and sentences (with oral and nasal consonants) was done using Nasometer II model 6450. The data were then analyzed using paired t-test and Wilcoxon statistical test. Results:The results indicate that the nasalance mean score for back vowels is significantly higher than front vowels. Also, the amount of nasalance mean score for low vowels is significantly higher than that in high vowels. The results also indicate that the nasalance mean scores for syllables, words, and sentences with nasal consonants is significantly higher than those with oral consonants (P<0.001). Conclusion:The results of the present study have provided the mean scores of nasalance for vowels, syllables, words, and sentences separately with oral and nasal consonants in normal Persian-speaking adults. Also, the data obtained in this study can be used to compare the function of the resonance system in people with suspected resonant disorders.
