Sound Radiation Modeling

Using the geometry and the vibration data the SPL frequency response is predicted in the far-field at the point r(ro,f, q) on basis of the Rayleigh integral equation. Critical frequencies for the sound radiation can be easily found and analyzed.

For a selected frequency the total SPL at certain points on a hemisphere over the cone can be determined and displayed in a polar directivity plot.

  • Show contribution to sound pressure output

  • Predict directivity pattern

  • Identify critical frequencies
