Point sound source--Acoustic attenuation anomaly

Please login with a confirmed email address before reporting spam

Hello,everyone. I am a novice user of COMSOL. I tried to use the Pressure Acoustics-Transient Interface to simulate sound propagation. I create a point in the 3D model as a point sound source. In the physical field option, right-click to select Point and select Pressure in its expansion options. In the Pressure (Point Condition) setting interface, import a P-t curve in the pressure option. The peak pressure of P-t curve is 270pa,but in the calculation results, the peak pressure at 0.1M away from the sound source point is only 2Pa, it is clearly wrong. Is this the wrong choice of my sound source or the limitation of COMSOL itself? Thank you for your help!!
