Cochlear electrode pitch can be probed by acoustic tones or direct biphasic stimulation.

Evidence

The determination of discriminable and indiscriminable electrodes was based on two approaches, acoustic tones presented at the centre frequency of a filter via the System for Testing Auditory Responses (STAR; Saleh et al. 2013 ) and direct stimulation with biphasic pulses delivered using the NIC. — Dijk, Pim van, Physiology, Psychoacoustics and…, 2096

• QUESTION: What is the STAR system, and why might acoustic and direct-stimulation pitch measures diverge?
