title: [Relationship between voice spectrum analysis and psychoacoustic evaluation in patients with vocal cords polyps].
abstract: The purpose of this paper is to investigate the significance of selected acoustic parameters, to determine their usfulness in monitoring effects of treatments, to correlate them to other clinical voice tests (such as aerodynamic measurements, stroboscopic examination, psychoacoustic evaluation), and to determin if there were correlations among the acoustic parameters. The results showed that pitch perturbation quotient (PPQ), amplitude perturbation quotient (APQ), normalized noise energy a and b (NNEa and NNEb) were positively related to the regularity (REG) in the vocal cord polyp. In the present study, psychoacoustic rough (R), breathy (B) were correlated to the regularity (REG), glottic closure (GLO) and the mean airflow rate. The integrated voice analysis was a simple and effective method for acoustic evaluation of pathologic voice.
