Voila je cherche a maitriser ce logiciel pour comprendre un peu plus les simulations.  
Ce logiciel me parait tres complet mais il y a une fonction que je ne comprends pas:  
 
Include > On-Axis Piston Band Response  
 
Includes the on-axis piston band response—if the diaphragm diameter (Dia) or diaphragm area (Sd) of the driver has been entered. The graphs affected by this option are: the Normalized Amplitude Response and Custom Amplitude Response. The “piston band” is the frequency band where the driver maintains a constant load versus frequency. This begins at the frequency whose wavelength is equal to the circumference of the piston and it extends upward in frequency. In the piston band, the on-axis response of most drivers will begin to increase with frequency at a rate of 6 dB/octave because the beamwidth or coverage angle of the driver will gradually narrow as the frequency increases

Est ce que quelqu un pourrait m en dire un peu plus sur cette fonction , a quoi elle sert ,importante ou pas etc etc ....  
 
enfin bref je suis preneur de toutes infos  
 
merci par avance
