This paper describes the Musical Poi (mPoi), a unique sensorbased musical instrument inspired by the ancient art of Jwibulnori and Poi spinning. The trajectory of circular motion drawn by the performance and the momentum of the mPoi instrument is converted to the energetic and vibrant sound, which creates a spiritual and meditative soundscape that opens everyone up the aura and clears the mind....

Introduction: Children with cochlear implants (CIs) may experience few opportunities for positive musical experiences, and musical perception is therefore often not sufficiently developed. This paper investigates and discusses the relationship between intelligence quotient (IQ) and musical ability in children with CIs compared with children with normal hearing.                                  ...

The impact of music and its psychological and physiological changes during exercise is issue that has always been focused on sport science experts. The aim of this study was to compare the effects of musical exercise on aerobic capacity and quality of life in elderly men. This study was conducted on 45 elderly men. The participants were randomly allocated into three groups: aerobic musical exer...

Many physical models of sustained musical instruments (strings, brass, reeds, flutes and voices) have been proposed by researchers in acoustics and computer music. We focus on an interesting class including a memoryless nonlinearity, a time-delay term and a filtering kernel in the delay line. Stability, oscillation, and other conditions for the dynamic behavior of this class of models are studi...

The aim of this paper is to study a conservative wave equation coupled to a diffusion equation. This coupled system naturally arises in musical acoustics when viscous and thermal effects at the wall of the duct of a wind instrument are taken into account. The resulting equation, known as Webster-Lokshin model, has variable coefficients in space, and a fractional derivative in time. This equatio...

Byzantine chants constitute a form of monophonic vocal music characterized by lengthy phrases and by musical scales with intervals smaller than the western music semitones. Byzantine churches have extremely long Reverberation Time and their acoustics is dominated by the contributions of the diffuse sound field. Thus, the sound character of Byzantine chanting is closely linked to the acoustic re...

The blind source separation problem is to extract the underlying source signals from a set of linear mixtures, where the mixing matrix is unknown. This situation is common in acoustics, radio, medical signal and image processing, hyperspectral imaging, and other areas. We suggest a two-stage separation process: a priori selection of a possibly overcomplete signal dictionary (for instance, a wav...

The Virtual Singing Studio (VSS) is a loudspeaker-based room acoustics simulation for real-time musical performance under development at the AudioLab, University of York. An objective evaluation of the VSS found that relative differences between T30 values of the input (real) and output (virtual) Room Impulse Responses fall within the double tolerance subjective limen (10%). In addition a consi...

– The main idea of this work is based on the following philosophy: To achieve the ideal compression of audio and video information, utilize the algorithm of information processing intrinsic in the human audio and video systems. In our work, using the results of physiology, musical acoustics and video perception theory, we show that the model of audio and video information processing can be desc...

A real-time virtual audio reality model has been created. The system includes model-based sound synthesizers, geometrical room acoustics modeling, binaural auralization for headphone or loudspeaker listening, and hiqh-quality animation. This paper discusses the following subsystems of the designed environment: The implementation of the audio processing softand hardware, and the design of a dedi...
