Abstract
At present, the design that utilized human sensitivity is demanded. It is necessary for exploiting human sensitivity to measure it. The paired comparison is one of the sensory evaluation methods, especially Scheffe's paired comparison evaluates the human sensitivity and adds a relative score to the samples that have a little differences. However, the conventional Schffe's paired comparison can separate the main effects, differences among individuals, order effects and combination effects. If there will be the other factors that have an effect on the samples' evaluation, the effects will be neglected. The new sensory evaluation method that is proposed in this paper enables to separate main effects, differences among individuals, combination effects, and another effects. In this paper, we propose this new method and apply it to the loud speakers' psycho-acoustic evaluation.
