| ABSTRACT |
Background and Objectives:
The purpose of this study is to find features in acoustics and to learn useful features of parameters in order to distinguish laryngeal diseases through many acoustic variables.
Materials and Methods:
The subjects of this study were 125-male patients who had been diagnosed with vocal nodule, vocal polyp, vocal cyst, Reinke's edema, leukoplakia. To research the features of each disease in acoustics, they are measured 34 parameters by using MDVP.
Results:
It is clear that in order to see a meaning result when distinguishing laryngeal diseases, $F_0$, $MF_0$, $T_0$, Fhi, Flo, PER variables are significant (p<.05). It means that variables related to fundamental frequency are important to anticipate which group will be diagnosed with Reinke's edema and leukoplakia. vAm had an effect on getting a significant result in terms of amplitude perturbation parameters, which is useful to distinguish between laryngeal polyp/cyst and other laryngeal disease (p<.05). ATRI made a significant result in related to tremor parameters, which is useful to distinguish between laryngeal polyp and other laryngeal disease (p<.05).
Conclusion:
$F_0$, $MF_0$, $T_0$, Fhi, Flo, PER, vAm, ATRI might be meaningful parameters distinguishing pathologic from benign laryngeal diseases. Especially, the vAm and ATRI are an important factor when forecasting which group would be diagnosed with vocal polyp. |
