Observational analysis establishes equivalence between acoustic and electrical thresholds, suggesting pathways for non-invasive hearing methods.
Objective Transmitting auditory information through non-invasive electrical conduction warrants greater investigation for medical, entertainment, and military purposes. The objective of the current study is to establish threshold equivalence between acoustic stimulation, measured in sound pressure level decibels (dB SPL), with electrical stimulation amplitude, measured in milliamperes (mA).
