Abstract:
Objective This study aimed to develop reading material for nasalance evaluation ,and find out na-salance scores associated with genders .Methods The NasalView ? (Tiger Electronics Inc .,Seattle ,USA) was used to obtain nasalance values in the new and old material .A total of 102 subjects (51 males ,51 females) who have lived in Beijing for 18 years or longer at the time of the experiment received the tests ,the results from two pieces of material and the mean nasalance gender score differences were compared .Results The mean nasalance scores of sen-tences were 56 .58% ± 3 .43% for'Nasal sentence',33 .86% ± 5 .24% for'Oral sentence',and 49 .49% ± 4 .13% for'Oro -nasal sentence'respectively in the new material .The mean nasalance scores of sentences were 54 .31% ± 4 .43% for'Nasal sentence',35 .64% ± 5 .90% for'Oral sentence',and 47 .12% ± 4 .96% for'Oro-nasal sentence're-spectively in the old material .There were significant differences between males and females through materials .The nasalance gender score differences showed that females were bigger than males (P<0 .01) .This study found a cor-relation between the new and old materials :'Nasal sentence'(r=0 .899 ,P< 0 .01) ,'Oral sentence'(r= 0 .850 ,P<0 .01) ,and'Oro -nasal sentence'(r=0 .851 ,P<0 .01) .The standard error difference showed that the new was smaller than the old (P<0 .01) .Conclusion The new material for nasalance evaluation has a better test validity ,and there is a high correlation between the old materials .The usage of the new material for nasalance evaluation will produce more accurate results with higher credibility .Normal female's nasalance scores were higher than males .
