Abstract

Background and Aim: Aerodynamic data can be used in diagnosis, evaluation on and treatment of complex problems, including vocal nodules, hypernasality, articulation errors, VOICE, disorders, laryngeal disease, respiratory disease and pulmonary conditions. The purpose of the study was to determine the average PHONATION time, PHONATION volume and airflow rate, as well as, the relationship between each of these parameters during two conditions (normal and deep BREATHs). Materials and Methods: The method used in this research is a cross-sectional, descriptive-analytical and was done by 103 subjects including 67 males and 36 females. A tape recorder with a VUmeter and a microphone was used to record PHONATION and control loudness. A stopwatch was used during the experimental session to measure PHONATION time. A 9 litter respirometer was used to produce a permanent record of the PHONATION and lung volume of each subject Finally, data were analyzed with descriptive and analytical (t-test, Pearson Correlation) statistic. Results: According to the effect of different conditions-normal BREATH and deep BREATH-the results showed that the PHONATION time, PHONATION volume and air flow during deep BREATH are significantly greater than those during normal BREATH(P<0/05). With respect to sex differences, most of findings showed statistically significant differences in PHONATION time, PHONATION volume and mean air flow rate between males and females during normal BREATH as well as deep BREATH(p<0/05).The mean PHONATION times of vowels /u/ and /i/ were statistically significant longer than that of vowel /a/ during normal and deep breathes (P<0/05).The mean PHONATION volume of vowel /a/ was statistically significant greater than those of vowels /u/ and /i/ during normal BREATH. There was a positive relationship between PHONATION time and PHONATION volume and so, there was a high positive relationship between mean PHONATION volume and mean air flow rate. In other hand, there was a negative relationship between mean PHONATION time and mean air flow rate both normal and deep BREATHes. Conclusions: The results showed that the values of air flow rate mean, PHONATION volume and airflow rate during deep BREATH were significantly greater than those during normal BREATH and results indicated that the parameters for males were significantly greater than those for females. The PHONATION time was inversely related to the air flow rate, however, there was a positive relationship between PHONATION time and PHONATION volume, as well as, between PHONATION volume and airflow rate
