Modulating target sounds at tACS frequency lets listeners sample at fixed phase

Evidence

Target sounds were modulated at the tACS frequency (4 Hz) to give listeners the opportunity to sample the target at fixed phase angle on consecutive tACS cycles. — Dijk, Pim van, Physiology, Psychoacoustics and…, 4777
