Polar Far-Field Measurement (POL)

MMT
  • Measurement under free field condition
  • Directivity in polar coordinates
  • Automatic control of turn-tables
  • 2D and 3D Display modes (polar, balloon)
  • Open Export Interface (ASCII)

The POL module offers a fully automated measurement of the sound pressure on a spherical surface under free-field conditions in polar coordinates φ, θ and r. The measurement distance (r) should be larger than the largest dimension (d) of the device (r>>d) and the longest wavelength (r>>λ) to measure directivity in the far field.
