Hi,

I like to use a monopole acoustic source but with an amplitude that varies with frequency. Is this possible ? I could imagine to have an acoustic source with an amplitude vector and a frequency vector.

Best regards

Stefan Willems

Stefan,

Use expression or interpolation function to define source amplitude as a function of frequency. Then, multiply source by the defined expression. The last step is to add parametric sweep over the source frequency, as shown in the attached mph file.
