[The application of aerodynamic method for the evaluation of the efficiency of the vocal, articulation and respiratory organs during singing and playing wind instruments].
This paper discusses the application of the aerodynamic method for the estimation of the efficiency of the vocal articulation and respiratory organ during singing and playing wind instruments. An evaluation of the vocal and respiratory organ was carried out on the basis of an analysis and correlation between the following parameters: PV--phonation volume, MPT--maximum phonation/playing time, SP--subglottal/blowing pressure, MFR--mean flow rate, GR--glottal resistance, EP--expiratory power, W--work. Volume and airflow was measured by a pneumotachometr with an electronic spirometer. The application of a plethysmographic booth made it possible to carry out non-invasive, indirect measurements of the subglottal and blowing pressure. Changes of pressure during singing and playing were recorded in the form of an aerodynamogram curve. This curve was used to determine the maximum duration of sound. Other quantities were derived from a mathematical analysis.
