A system measuring immittance variation, based on simultaneous measurement of two parameters of resistance increments in a four-terminal (4T) network, can be an example [9].
A more definitive study would test patients' hearing, including the attainment of extended high frequencies (beyond 8000 Hz), measurement of otoacoustic emissions, immittance testing, and speech testing, before (baseline testing) and after they started using the medication.
