Hello

 

I would like to calculate ERP at 3 points a distance of 1000 mm in X, Y and Z directions from a component. 

 

Please let me know the relevant cards and provide the reference deck if possible.

 

Thanks in advance,

Ravi.

    Hi Prakash,

     

    Thank you very much for your response.

     

    I am trying to calculate the ERP of the same panel at 2 microphone locations (1m radius and 2.5m radius from the centre of the panel). I am getting the same result in both the cases. Also, the ERP result is same with MIC, defined using the RADSND and without MIC, default calculation with ERPPNL. I am interested to calculate the radiated sound at various distances from the source.  Please let me know your suggestion.

     

    Ravi.
