Velocity Displcement Calibration for Sound and Vibration Tool Kit

[sound nt]

Hello Guys,

I have been working on sound and vibration tool kit recently.

I'm taking input from sound port of PC by signal generator and taking single and double Integration for velocity and displacement resp.

I want to check the correctness of the values for different amplitudes,and different frequencies of signal, velocity and displacement. 

The RMS values for signal is calibrated as per signal generator, RMS value for the Velocity is correct for a limited frequency range 

and the RMS value for the displacement is not at all calibrated for any of the frequency. 

I will appreciate replies,

Hey guys,

The following vi is working for the signal generated with in Labview but if the signal is taken from mic port through signal generator.

then the velocity and displacement is not coming.

i'm attaching vi below kindly  reply if someone get something
