The study of vibroacoustic properties of small wind turbines with a vertical axis laboratory test conditions used in the form of an anechoic chamber in the Acoustics Laboratory, Institute of Energy, Department of Heat in. Anechoic chamber design allowed the installation of a duct through which the airflow is adjusted by means of a centrifugal fan mounted at the inlet of the waveguide. The paper presents the identification of the acoustic parameters of acoustic small wind turbines with a vertical axis comprising: a) determination of sound power levels for different classes of frequency characteristics and test wind turbines work b) identification of the components of the spectrum frequency - amplitude associated mainly with turbine speeds and frequencies of their own, such as duct The result of research was to obtain input data to define a more dedicated to the identification of measurement noise and vibration characteristics of wind turbines such as the efficiency of vibroacoustic, cepstrum analysis or dimensional analysis.
