If i have the driver velocity Ud.
how can i work out the pressure level from that?
I'm guessing its gotta be something like
Ud * Sd * p * c
Ud = Driver Velocity
Sd = Cone Area
p = Density of air
c = Speed of sound
I'm not quite sure though, does anyone have any ideas?
I'm calculating Ud (in an infinite baffle) using:
Ud = Pg / ((1 / jwCas) + jwMas + Rat)
Pg = Acoustic Driving Pressure = (eg Bl) / (ReSd)
Cas = Acoustic Compliance = Vas / (pc^2)
Mas = Acoustic Mass (not too sure how to calculate this?) Maybe (1 / (fs^2 * Cas))
Rad = (Bl^2 / Sd^2) * (Qes / (Re * Qms))
Rat = Total Acoustic Resistance = Rad + (Bl^2 / (Sd^2 (Re + jwLvc)))
