Nasalance Scores for Normal Persian-Speaking Girls

Background: Obtaining normative nasalance scores is essential in the process of assessing and treating resonance disorders. The purpose of this study was to obtain nasalance scores in Persian- speaking girls aged 4-6 years and investigate the age-related differences. Materials and Methods: All participants (n=40) were screened to identify any overt problems relating to resonance, hearing, voice quality, or speech and language skills. The mean nasalance scores were obtained from normal-speaking girls during the repetition of the Persian version of the Simplified Nasometric Assessment Procedures (SNAP) test subtests. The Nasometer II (model 6450) was used to obtain the nasalance scores. Results: The mean nasalance score for the SNAP test subtests was obtained. Group mean and standard deviation (SD) nasalance scores of girls for oral and nasal sentences were 12.59 ± 3.74 and 50.52 ± 6.39, respectively. There was no significant difference between age groups (4, 5 and 6 years old) (P 0.05). Conclusion: Our results provided normative nasalance scores based on the SNAP test that can be used for the evaluation and treatment of resonance problems in Persian-speaking girls.
