the equation i used for a is sm=delta(pm)/(vpw)

where p is the density, sm is the displacement amplitude, pm is the pressure amplitude, v is the velocity, and w is the angular frequency.

I could find all of the variables from the equation but the velocity (pm=1.13 x 10^-3, p=1.21, w=2pif=2pi x 1665)

Thanks in advance.
