Modelling the Sound Radiation by Loudspeaker Cabinets
While musical instruments often rely on a body which resonates on purposefully to amplify the vibration produced by a string or a membrane, such as in a violin or a guitar, loudspeaker cabinets should not contribute at all to the total sound radiation, but aim instead to be a perfectly rigid box which encloses the drive units in charge to transform the electrical signal at their terminal into a...

متن کاملThe ‘Virtualmonium’: an instrument for classical sound diffusion over a virtual loudspeaker orchestra
Despite increasingly accessible and user-friendly multi-channel compositional tools, many composers still choose stereo formats for their work, where the compositional process is allied to diffusion performance over a ‘classical’ loudspeaker orchestra. Although such orchestras remain common within UK institutions as well as in France, they are in decline in the rest of the world. In contrast, p...
متن کاملEffects of mirror reflection versus diffusion anisotropy on particle acceleration in oblique shocks
Cosmic ray particles are more rapidly accelerated in oblique shocks, with the magnetic field inclined with respect to the shock normal direction, than in parallel shocks, as a result of mirror reflection at the shock surface and slower diffusion in the shock normal direction. We investigate quantitatively how these effects contribute to reducing the acceleration time over the whole range of mag...
متن کاملDirectional Derivatives of Oblique Reflection Maps
Given an oblique reflection map Γ and functions ψ, χ ∈ Dlim (the space of R -valued functions that have finite left and right limits at every point), the directional derivative ∇χΓ(ψ) of Γ along χ, evaluated at ψ, is defined to be the pointwise limit, as ε ↓ 0, of the family of functions ∇εχΓ(ψ) . = ε [Γ(ψ + εχ) − Γ(ψ)]. Directional derivatives are shown to exist and lie in Dlim for oblique ref...
