Guwahati: A new scientific study has examined the distinctive wordless humming style that has long been associated with singer Zubeen Garg, finding that it contains measurable acoustic properties that may explain its strong emotional impact on listeners.
Published in the Journal of Voice, the official journal of The Voice Foundation and the International Association of Phonosurgery in the United States, the paper represents the first systematic acoustic analysis of Garg’s humming technique.
Titled “Quantitative Acoustic Profiling of Zubeen Garg’s Humming: Temporal Patterning and Spectral Balance,” the study was carried out by Kishore Dutta of Handique Girls’ College, Guwahati, along with independent researcher Jyotshna Saikia, who specialises in natural language processing and computational analysis.
The researchers used quantitative acoustic profiling to compare samples of Garg’s humming with his conventional singing voice. Their analysis focused on key vocal parameters such as jitter, shimmer, harmonic-to-noise ratio (HNR) and timbral qualities to distinguish the two vocal forms.
Findings indicate that the humming is marked by a more stable vocal pattern, a lower fundamental frequency, and a pronounced harmonic structure. These characteristics collectively contribute to a soothing and emotionally resonant sound perception among listeners.
The study also identified statistically significant differences between his humming and singing across multiple sound-quality metrics, suggesting that the humming functions as a distinct vocal expression rather than a simplified extension of singing.
Researchers noted that this blend of acoustic steadiness and subtle variation enhances its expressive depth, which has become a defining feature of Garg’s musical identity.
Although the humming style has been widely appreciated by fans and discussed in popular culture, it had not previously been subjected to rigorous scientific evaluation.
The authors argue that Garg’s humming represents a unique mode of vocal production defined by quantifiable acoustic traits, demonstrating how artistic expression can be examined through modern voice science methodologies.
More broadly, the study underscores the expanding use of acoustic analysis in exploring vocal identity, musical expression and audience perception. For Assam’s music landscape, the findings place a culturally significant vocal style within the scope of international scientific research, highlighting its cross-disciplinary relevance.
