A Preliminary Investigation on Frequency Dependant Cues for Human Emotions

The recent advances in Human-Computer Interaction and Artificial Intelligence have significantly increased the importance of identifying human emotions from different sensory cues. Hence, understanding underlying relationships between cues become a subject study many fields including Acoustics, Psychology, Psychiatry, Neuroscience Biochemistry. This work is preliminary step towards investigating for emotion on fundamental level by aiming to establish tonal frequencies sound emotions. For that, an online perception test conducted, which participants are asked rate perceived corresponding each tone. results show that crossover point four primary lies frequency range 417–440 Hz, thus consolidating hypothesis 432–440 Hz neutral perspective. It also observed dependant pairs Happy—Sad, Anger—Calm approximately mirrored symmetric nature.
