Pomiar cyfrowy wartości rezonansu nosowego w populacji dorosłych Polaków

Introduction: Nasality is the subjective perception of an abnormal nasal resonance value in speech. An objective measure of nasality is nasalance, expressing the ratio of nasal resonance to the combined value of nasal and oral resonance. Aim: The aim of this study was to measure the proportion of nasal resonance during articulation, in a population of healthy adult Poles, on a digital nazometer. Another aim was to test whether articulation tests developed in the past to assess nasal resonance can be used on modern digital devices. Material and methods: The material in this study consisted of 45 subjects with normal speech development, normal hearing and no abnormalities in otolaryngological-phoniatric examination. Patients were examined with language tests developed by Gąsiorek. Tests I, III and VII were used. Results: Mean nasality scores (meanN) during the first test containing vowels (śrNI) in the entire study group was 18.6% (SD 8.8%); the test containing sentences (śrNIII) 14.7% (SD 4.1%); during reading text śrNVII 11.9% (SD 3.8%). Statistical analysis showed no significant differences between gender and the results obtained in each test. The limit value of the normative index of nasal resonance participation was determined. Normal values were obtained – 20% in test III and 17% in test VII. As a result of the research, the share of nasal resonance during articulation was determined in the population of healthy adult Poles on the basis of current methodological standards.

In the opinion of the authors, it is recommended to use differentiated language tests for children and adults.
