We have conducted basic experiments for applying acoustic information to engineering problems. We asked the subjects to execute lifting actions while listening to sounds and measured the resultant lifting-force.
We used human onomatopoeic utterances as the sounds that are presented to the subjects aiming to make their lifting-force small.
Especially, we focused on the “emotion” or “nuance” contained in humans’ utterances, which is a unique characteristic evoked by the utterance’ acoustical features. We found that the emotion or nuance can control the lifting-force effectively. We also clarified the acoustical features that are responsible for effective control of lifting-force exerted by human.
