Abstract/OtherAbstract:
Objective : This study compared measures of nasalance obtained using the Nasometer 6200 versus the Nasometer II 6400 in typically speaking young adult males and females for the nonnasal Zoo Passage, the phonetically balanced Rainbow Passage, and the Nasal Sentences. Design : Participants read passages at a comfortable pitch and loudness twice while wearing Nasometer 6200 or Nasometer II 6400 headgear. The order of Nasometer system was counterbalanced across participants, and the order of the reading passage was randomized. Participants : Participants consisted of 25 males (mean age = 21.22 years) and 25 females (mean age = 23.83 years). Main Outcome Measures : The main outcomes measures were nasalance scores (%) obtained for each system × passage per participant. Results : Results showed that the Nasometer 6200 and the Nasometer II 6400 differed significantly on mean nasalance for the Zoo Passage (mean difference = 7.15%) and the Rainbow Passage (mean difference = 3.05%) but not for the Nasal Sentences (mean difference = 0.77%). Intersystem correlations and measures of predictive accuracy indicated that the ability to predict Nasometer 6200 nasalance scores from Nasometer II 6400 scores was relatively weak. Conclusions : In addition to such factors as age, gender, and regional dialect, normative nasalance expectations and normal versus disordered nasalance cutoff scores must be considered with full knowledge of the specific system that was used to acquire the nasalance data. Intrasubject changes in nasalance can only be validly assessed when test versus retest measurements have been acquired using the same nasalance system.
