  Hello! I am struggling to obtain good results. Can someone help me?
  I already have a single body composed of air.
  I already have the mesh.
  I have already defined absorption coefficients.
  I have a loudspeaker as a source with a sound level of 70.4 dB. What kind of source should I use? What do I need to do to obtain results that are the most accurate representation of real life? At a specific point, I need to achieve a sound level of 61.8 dB. The measurement without the noise source is 40.6 dB. Do I need to define this? If so, how can I do it? I am unable to locate the manual that could assist me.
  I am using version 18.2
  Please help.
