Tibetan singing bowls are employed worldwide for meditation, music, relaxation, personal wellbeing, and religious practices. Each Tibetan bowl can produce a limited number of sounds, defined by the size and material of the bowl, and the actuator device used. Usually, there is a need for a second person to actuate the bowl. Addressing these limitations, we built an electronic device, named eBowl, which can mimic the acoustics of Tibetan bowls, and beyond that, can produce a wide range of other… Expand

Figures and Tables from this paper

Metallic signing bowls are used in sound therapy and in Buddhist prayers are widely studied for their resonance frequency modes [13,2]. Studies have also been carried out to understand the resonanceExpand
Sound radiation of a circular piston in the outlet of a finite hemispherical cavity of a finite inner impedance
Abstract This study deals with the problem of sound radiation by a vibrating circular piston embedded in the outlet of a thick hemispherical cavity. It is assumed that the inner surface of the cavityExpand


The dynamics of Tibetan singing bowls
Tibetan bowls have been traditionally used for ceremonial and meditation purposes, but are also increasingly being used in contemporary music-making. They are handcrafted using alloys of severalExpand

1) Oster’s idea was to use the perception of binaural beats as a diagnostic tool because some people are unable to perceive and respond to them, which seems to follow in line with the research done by David Seiver, Transparent Corp and others in regards to monaural and isochronic tones producing stronger entrainment.

Binaural Auditory Beats Affect Vigilance Performance and Mood
Results suggest that the presentation of binaural auditory beats can affect psychomotor performance and mood and this technology may have applications for the control of attention and arousal and the enhancement of human performance. Expand
Reproducing low-pitched signals through small loudspeakers
Ever since the invention of the electrodynamic loudspeaker there has been a need for greater acoustical output, especially at low frequencies. From a manufacturer’s point of view it has beenExpand
Introduction to the Psychology of Hearing
The author's stated general approach is to relate the psychological and perceptual aspects of sound to the underlying physiological mechanisms of hearing in a way that the material can be used as aExpand
Human auditory steady state responses to binaural and monaural beats
The dependence of the 40Hz binaural beat ASSR on stimuli at low, temporally coded tone frequencies suggests that it may objectively assess temporal sound coding ability. Expand
Tibetan singing bowls
We present the results of an experimental investigation of the acoustics and fluid dynamics of Tibetan singing bowls. Their acoustic behaviour is rationalized in terms of the related dynamics ofExpand
A modal method for the simulation of nonlinear dynamical systems with application to bowed musical intruments
Bowed instruments are among the most exciting sound sources in the musical world, mostly because of the expressivity they allow to a musician or the variety of sounds they can generate. From theExpand
A comparison of auditory evoked potentials to acoustic beats and to binaural beats
The perceptions of binaural beats involve cortical activity that is not different than acoustic beats in distribution and in the effects of beat- and base frequency, indicating similar cortical processing. Expand
Phase synchrony analysis for SSVEP-based BCIs
The result shows that the phase synchrony analysis can effectively extract the phase difference and that spatial filtering can significantly increase the classification accuracy. Expand
