This paper illustrates the demonstration of sonic emotion 3D sound technology for compact loudspeaker arrays. The technology combines stereo/5.1 spatial analysis techniques with advanced sound field control techniques based on Wave Field Synthesis for optimum sound rendering of stereo/5.1 content within an extended listening area. sonic emotion offers a complete solution in the form of a chip t...

This paper investigates the feasibility to use an electrodynamic loudspeaker to determine viscoelastic properties of sound-absorbing materials in the audible frequency range. The loudspeaker compresses the porous sample in a cavity, and a measurement of its electrical impedance allows one to determine the mechanical impedance of the sample: no additional sensors are required. Viscoelastic prope...

Pembelajaran di MI se derajat saat ini harus lebih ditekankan tidak hanya pada aspek pengetahuan, tetapi juga untuk keterampilan dan kreativitas siswa. Materi pelajaran merupakan salah satu materi magnet yang diajarkan siswa Sederajat. Model pembelajaran menggunakan media cenderung mengenal konsep tanpa mengetahui penerapan ini. Jika kutub disandingkan maka sama akan saling tolak menolak. Metod...

Wave Field Synthesis provides the possibility to synthesize virtual sound sources located between the loudspeaker array and the listener. Such sources are known as focused sources. Previous studies have shown that the reproduction of focused sources is subject to audible artifacts. The strength of those artifacts heavily depends on the length of the loudspeaker array. This paper proposes a meth...

An immersive audio environment for desktop applications is presented. It allows the spatialisation of 3D sound fields around an almost free mobile listener. The sound field is reproduced by a several loudspeakers positioned along the desktop edges without using head tracking. The loudspeaker signals are derived by using the principle of the wave field synthesis approach combined with different ...

Wave Field Synthesis provides the possibility to reproduce virtual sound sources located between the loudspeaker array and the listener. Such sources are known as focused sources. A previously published study including an informal listening test has shown that the reproduction of focused sources is subject to audible artifacts, especially for large loudspeaker arrays. The combination of the tim...

Wave Field Synthesis (WFS) is a physical based sound reproduction technique. It relies on linear arrays of regularly spaced omnidirectional loudspeakers. A fundamental limitation of WFS is that the synthesis remains correct only up to a corner frequency referred to as spatial aliasing frequency. This paper addresses irregular spacing of loudspeaker array for WFS. Adapted driving functions are d...

With the author’s own experiences in mind, this paper argues that, when used to amplify musical instruments or to play back other sonic material to an audience, loudspeakers and the technology that drives them, can be considered as a musical instrument. Particularly in situations with acoustic instruments this perspective can provide insight into the often cumbersome relation between the –techn...
