tACS perceptual benefits so far are modest and often statistically marginal
Evidence
Due to the limited spatial specificity of transcranial stimulation, individual tonotopic locations cannot be selectively targeted. Nevertheless, the possibility to transmit sound envelope information non-invasively and bypass (possible deficits in) the auditory pathway up to the cortex might make transcranial stimulation a valuable tool. — Dijk, Pim van, Physiology, Psychoacoustics and…, 4768 (
