To get a sensitive measurement, you should measure a coherent transfer function, not just noise. We expect the thermo-elastic effect to be linear. Try making a swept-sine measurement and fiddle with the integration time to get a measurement. Even it ends up being a very small signal, you can use the measurement parameters and the HP Application Note #243 to set an upper limit on the coupling.
