Determination of sound power levels of heating equipment by measurement of the acoustic intensity
 Wagnerová, Klára ; Doložílek, Miroslav (referee) ; Jedelský, Jan (advisor)
This thesis concerns method of determining sound power level of heating devices from acoustic intensity as a primary measured value. Thesis describes the characteristics of acoustic parameters and principles of acoustic measuring. Method of measurement at discret points according to ČSN EN ISO 9614-1 is compared with measurement by scanning according to ČSN ISO 9614-2. Methods are evaluated teoreticly as well as practically by companing results of experimental testing. Thesis also includes description of created model which evaluates acoustic measurement acording to the definitionof point method. The model is designed for measuring chain of Engineering Test Institute, Public Enterprise (SZU).
