Abstract

|
|
The purpose of this study was to determine the correlation between HNR and NNE, EGG HNR and EGG NNE, which are most closely related to noise of voice. Dr. Speech was utilized to obtain acoustic measurements and physiologic measurements, simulta-neously. In addition, no normative data of HNR, NNE, EGG HNR, EGG NNE are available in Korean subjects at present. The Pearson correlation coefficient was used to find the correlation between HNR and NNE, EFF HNR and EGG NNE.
The results of the study were as follows:
First, there was no correlation between HNR and NNE.
Second, there was a negative correlation between EGG HNR and EGG NNE.
Finally, the mean value of HNR of normal Korean adults was 28.8±2.7 ㏈, that of NNE -11.7±3.9 ㏈, that of EGG HNR 32.9±4.6 ㏈, and that of EGG NNE -30.3±4.6 ㏈.
