Název v původním jazyce

Description of Secondary Sound Field Around a Spherical Obstacle

Popis výsledku v původním jazyce

Scattering and diffraction are phenomena still frequently discussed in acoustics. We are preparing a method for creating mathematical models of a secondary sound field for different shaped bodies. For preparation of this method, a spherical body was chosen because the comparison between experimental and analytical results is feasible. A concave spherical body made of glass was used for our experiments. Measurements were performed in an anechoic room, which is the model of a free field. The obtained numerical description of secondary sound field was compared to description calculated on the basis of analytical formula. A mathematical model of the secondary sound field measured is being prepared, and measurements with differently shaped bodies and theirmathematical models with respect to our experiences obtained up to now will be prepared.
