Acoustical Resonance in Humans through Determination of Individual Natural Frequency

Anirvan Gupta, Nivedita Azad

Abstract: In the auditory channel, humans are highly attuned to emotional signals in speech and music that arise from shifts in the frequency spectrum and intensity of sound. In this study, responses of human beings from various age groups were observed by exposing them to sinusoidal tones of frequency within human hearing range. Similar to a mechanical resonant system, human body also has an internal cavity, which, when exposed to an external frequency equal to its natural frequency, vibrates with maximum amplitude. An attempt was made to estimate the resonant frequency of an individual. The study is expected to throw light on acoustic environment most suited for an individual to make him realize a state of contentment when he is in an enclosure meant for worship or meditation. The study may also support people from medical background to treat a person through acoustical techniques.
