Acoustic-tone and direct-stimulation pitch tests yield highly correlated results
Evidence
The responses from the STAR and the NIC test were highly correlated (rho = 0.82, N = 13, p = 0.001) so the results from both tests were combined to create a composite score for each electrode by adding up the passes and fails across both tests thus increasing the calculation power. — Dijk, Pim van, Physiology, Psychoacoustics and…, 2099
