High-quality electret microphones and single-chip processors are economical enough to be used in large numbers. This latitude opens opportunities for dynamic source location and sound capture with spatial selectivity in three dimensions, This report discusses algorithms for matched-filter processing of microphone arrays and for coordinate tracking of moving talkers. A prototype conferencing sys...

The plane wave decomposition is an efficient analysis tool for multidimensional fields, particularly well fitted to the description of sound fields, whether these ones are continuous or discrete, obtained by a microphone array. In this article, a beamforming algorithm is presented in order to estimate the plane wave decomposition of the initial sound field. Our algorithm aims at deriving a spat...

The problem that often occurs is forgetting to turn off the lights when you want leave because are in a hurry, as result stay on and there waste of electricity. This research was conducted with aim designing an Automatic Light Turning Control System Using FC-04 Sound Sensor Based Arduino Uno. When detects input two hands clapping, relay will give current light object so it turns automatically. ...

Research and musical creation with gestural-oriented interfaces have recently seen a renewal of interest and activity at Ircam. In the course of several musical projects, issued either by from young composers enrolled in the Cursus of Composition and Computer Music or by guests artists, the Pedagogy and Creation departments of Ircam have proposed various solutions for gesture-controlled sound s...

adequate coverage is one of the main problems for distributed wireless sensor networks and the effectiveness of that highly depends on the sensor deployment scheme. given a finite number of sensors, optimizing the sensor deployment will provide sufficient sensor coverage and save power of sensors for movement to target location to adequate coverage. in this paper, we apply fuzzy logic system to...

This paper presents the first robotic system featuring audio-visual (AV) sensor fusion with neuromorphic sensors. We combine a pair of silicon cochleae and a silicon retina on a robotic platform to allow the robot to learn sound localization through self motion and visual feedback, using an adaptive ITD-based sound localization algorithm. After training, the robot can localize sound sources (wh...

Bimba is an exploration into designing playful interfaces which use embedded sensors to sonify object interactions. The system wirelessly collects data from sensors integrated into foam balls and generates a sound composition extracting the most relevant features of movement. We have designed and built a collection of sensor units, implemented a protocol to support a wireless real-time data net...

SenSynth is an open-source mobile application that allows for arbitrary, dynamic mapping between several sensors and sound synthesis parameters. In addition to synthesis techniques commonly found on mobile devices, SenSynth includes a scanned synthesis source for the audification of sensor data. Using SenSynth, we present a novel instrument based on the audification of accelerometer data and in...

Abstract The reflection and refraction of light are more familiar to students than the sound. Reflection that occur during transmission sound waves common phenomena in everyday life but often difficult understand actual learning. In this study, we developed a test apparatus can measure sound’s angles by injecting using super directional speaker with excellent straightness. Consequently, moving ...
