Evaluation of Curative Effects of Different Chronic Laryngitis by Voice Acoustic Analysis / 听力学及言语疾病杂志

ABSTRACT

Objective To investigate the application of the voice acoustic analysis in the evaluation of curative effects of different chronic laryngitis.Methods The adult patients with chronic laryngitis (80 cases)were divided into 3 different syndrome types what were as the Yin deficiency group (28 cases),the Qi deficiency group (25 ca-ses),and the TanNing blood stasis group (27 cases).According to the different compositions of golden voice series medicines,the medicines were administered,combined in two to three.A total of 30 normal people were set to the control group.The German ATMOS voice test and analysis system was used to detect continuous vowel signals and the results were compared before and after treatment.Results Before the treatment,the chronic laryngitis group, compared with control group,had higher jitters,shimmers and NHR.The MPT was significarry shorter and DSI smaller compared with the control group(P 0.05)ex-cept for the parameter-jitter.The jitter,shimmer,and NHR decreased significantly after 1 month treatment while the MPT and DSI increased significantly in the Yin deficiency group and the Qi deficiency group compared with be-fore treatment (P <0.05).There was a statistically significant difference on jitter,shimmer,NHR and DSI and no difference on MPT compared with before treatment in TanNing blood stasis group.Conclusion The voice acoustic a-nalysis could be objective and quantitative to analysis the chronic laryngitis patients'voice quality with different syn-drome types and evaluate the curative effects.
