Enhancing speech recall and reducing cognitive load through rhythmic amplitude modulated vibrotactile stimulation in noise (opens in new tab)

This study introduces and evaluates Rhythmic Amplitude Modulated Vibrational (RAM-Vib) stimulation for improving speech recall and reducing cognitive load in noisy environments. Building on multisensory integration and neural entrainment theories, three experiments tested and refined RAM-Vib for Japanese speech in noise. Initial experiments focused on speech perception and attention using either amplitude-envelope (Exp 1) or speech-rhythm alone (Exp 2). While these approaches reduced cognitiv...
