Illustration of the effect of the expander on the tactile signal amplitude for the sentence “He hit his head”. Panels A and B show the tactile signal for clean speech and for speech-in-noise (at 2.5 dB, the lowest SNR used in the study). Panel C shows the same signal as panel B, but with the expander on. The height of each channel waveform corresponds to the amplitude of the signal.
