MNOISE computes the acoustic parameters "mobility" , "surface noise level" and "sound pressure".

As input for MNOISE the results of a frequency response analysis or a MBS simulation (modal coordinates) can be used.

Frequency response analysis with random excitation (short: random response) is also supported. The mobility, surface noise level or sound pressure can be represented as follows:

  • Surface distributions (see image)
  • Mean values for certain areas: for efficient comparison of components
  • For individual selected nodes: for comparing two data points; these points can also be made audible using a WAV file
