The phrase "a simultaneous change in" is correct and usable in written English.
It can be used when discussing events or phenomena that occur at the same time and result in a change in a particular context.
Example: "The study observed a simultaneous change in temperature and pressure during the experiment."
Alternatives: "an concurrent alteration in" or "a simultaneous shift in".
A simultaneous change in time and frequency dissemination of the continuous wavelet transform can be observed.
Spitzer registered a simultaneous change in the amount of heat radiation, indicating that the two hemispheres have wildly different temperatures.

A simultaneous change in two or three of these formulation parameters (compared to a reference formulation) resulted in a synergistic effect on the HRP release profile.
One of the failure mechanisms occurs at potentials >0.5 V Li/Li+, and relates to an increase in the electrode's impedance due to improper passivation and a simultaneous change in the electrode's morphology, probably due to gas formation.
The difference was that the total deposition pressure kept invariable (2.0 Pa) and the nitrogen gas (N2, 99.999%) flow rate varied from 3 to 15% of the total gas flow rate with increments of three, accompanied by a simultaneous change in argon gas (Ar, 99.999%) flow rate.
The present study was triggered by a simultaneous change of instruments in both the core laboratory and on the wards.
"There has to be a simultaneous change at the environmental level, in schools, communities and families".
We did this because a simultaneous change from 1st to 5th quintile in all five indices is not the same as a 1st to 5th quintile change in the overall index.
However, collectively these results suggest that it is possible that such a mechanism of "local spread" could be driven by mechanisms that do not involve any type of spatial interaction between the neighboring farms (e.g., introduction from a common source, simultaneous change in management or prevalence of other component causes, or recall bias).
For white-color workers in an office building this simultaneous change in movement however has no clear meaning.
