Psychological Effects of Acoustics

Multiple experiments have been conducted to test the correlation between acoustics and human cognition. These experiments focused on how acoustics are, "perceived or experienced and/or understood by a person or people" (Blake), enabling researchers to develop an understanding of psychological effects of acoustics on a larger scale. In "Effects of Complex Aural Stimuli on Mental Performance", music is described as, "'[...] an effective tool to influence the mind", and that a single note has the ability to, "possibly change a person's mood, preferences, and taste, and even put him to sleep", expressing the multitude of persuasion acoustics possess over the brain. "Acoustic Analysis and Mood Classification of Pain-Relieving Music" takes a deeper biological look into the phenomenon stating, "[..] basic acoustical characteristics of music cause corresponding activation of the central nervous system." It has been concluded that the psychological effects of acoustics is also intensely related to the individual as viewed in "Music-induced emotions can be predicted from a combination of brain activity and acoustic features" which reads, "Thus, we suggest that a combination of both physiological measures of the listener and acoustic properties of the music may be used to effectively predict emotional responses to a piece of music", and "[...] both the relationships between the music features and the listener’s current neurophysiological state needs to be understood before the emotional response of a listener to a particular piece of music can be predicted" (Daly).
