Calculating Displacement & Intensity of 1665 Hz Wave

[QUOTE="JasonV, post: 1525916, member: 98203"] A sound wave has a frequency of 1665 Hz and a pressure amplitude of 1.13 x 10^-3 Pa. What were (a) the displacement amplitude and (b) the intensity of the wave emitted by the ear? 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. [/QUOTE]
