TL;DR
This study investigates how different musical frequency bands influence human brain activity using EEG, revealing frequency-specific neural responses that could inform cognitive music therapy.
Contribution
It introduces a novel neurocognitive approach combining wavelet transform and multifractal analysis to study brain responses to musical frequencies.
Findings
Frequency-specific arousal responses in brain lobes and EEG bands.
Distinct multifractal spectral widths linked to musical frequency bands.
Potential applications in cognitive music therapy.
Abstract
The term gestalt has been widely used in the field of psychology which defined the perception of human mind to group any object not in part but as a unified whole. Music in general is polytonic i.e. a combination of a number of pure tones (frequencies) mixed together in a manner that sounds harmonius. The study of human brain response due to different frequency groups of acoustic signal can give us an excellent insight regarding the neural and functional architecture of brain functions. In this work we have tried to analyze the effect of different frequency bands of music on the various frequency rhythms of human brain obtained from EEG data of 5 participants. Four (4) widely popular Rabindrasangeet clips were subjected to Wavelet Transform method for extracting five resonant frequency bands from the original music signal. These resonant frequency bands were presented to the subjects as…
