Abstract:
Objective To investigate the relationship between pleural resonance features and the chest volume and vital capacity in young male adults .Methods A total of 60 healthy young male adults were included in this study .Energy distribution of pleural resonance was measured with the multi-channel voice analysis system when they pronounced /a:/.The frequency spectrums were 0~999 Hz (FR1 ) ,1 000~1 999 Hz (FR2 ) ,2 000~2 999 Hz (FR3 ) ,3 000~4 000 Hz (FR4 ) .Fast 3D reconstruction of chest was detected by multi slice spiral CT to calcu‐late the chest volume .The vital capacity was evaluated by aerodynamics system .SPSS 18 .0 software was used to analyze the data .Results The vital capacity in healthy young male adults was 4 .31 ± 0 .63 L ,the chest volume was 5 .69 ± 0 .52 L .The frequency spectrum of FR1 was 53 .38% ± 2 .14% ,FR2 was 30 .72% ± 1 .59% ,FR3 was 10 . 53% ± 2 .75% ,FR4 was 5 .35% ± 2 .32% ,respectively .There was a highly positive correlation between the chest volume and FR1 (r=0 .854) ,moderately positive correlation between the volume and FR2 (r=0 .740) ,moderately negative correlation between the volume and FR3 (r= -0 .587) ,moderately negative correlation between the volume and FR4 (r= -0 .565);There was a highly positive correlation between the vital capacity and FR1 (r=0 .744) ,mod‐erately positive correlation between the volume and FR2 (r=0 .699) ,moderately negative correlation between thevolume and FR3 (r= -0 .632) ,weakly negative correlation between the volume and FR4 (r= -0 .429) .Conclusion There was a high correlation between the chest volume and pleural resonance ,high correlation between vital capacity and pleural resonance in young male adults ,which may be a influencing factor of pronunciation effect .
