A large group of students were tested for their ability to distinguish among different tones. Although tone A and tone Bwere slightly different, more than half of the group thought that they sounded exactly the same. The difference between tone A and tone B can be said to be less than the:

The fact that more than half of the group could not distinguish between tone A and tone B suggests that the difference between the two tones is less than the difference threshold, also known as the just noticeable difference (JND). The JND is the smallest detectable difference between two stimuli, and it varies depending on the type of stimulus and individual differences. Therefore, option A is the best choice. The absolute threshold (B) refers to the minimum amount of stimulus energy required to detect a stimulus, while the subliminal threshold (C) refers to stimuli that are below the threshold of conscious awareness. Weber's threshold (D) refers to the proportional difference between stimuli required for detection.
