The threshold refers to the minimum intensity level at which a stimulus can be detected. In this case, the sounds presented to Mr. Antall were presented at such low levels of intensity that he could hardly detect them, indicating that they were below his absolute threshold. "Subliminal" refers to stimuli that are presented below the threshold of conscious awareness, "adaptation" refers to a change in perceptual sensitivity over time, and "difference" refers to the smallest detectable difference between two stimuli.
