Emotional Cues in Knocking Sounds

Background Acoustics features in music and sound and their connection to body gestures have already been investigated in previous scientific studies, such in the case of musician movements while playing an instrument, or footstep sounds. It has also been proved that humans are able to visually identify emotions in gestures only as suggested for example by previous studies on musician and non-musicians movements, as in the case of arm/hand movements in knocking. In particular, after successful studies in identifying acoustical cues in emotional walking and finding their high correlation with acoustical cues used in expressive music performance, we would like to investigate if the same similarities could be found in emotional knocking sounds.
