Acoustic energy density’s dependence on particle velocity as well as acoustic pressure makes it a good candidate for an error signal in an adaptive noise control algorithm. It has been shown that minimizing acoustic energy density often provides more global attenuation of an enclosed sound field than minimizing squared acoustic pressure. Nodal regions in three-dimensional enclosed sound fields ...

Using the Advanced Microwave Scanning Radiometer sensor (AMSR-E), winter (October to May) sea ice area flux is estimated for the main channels of the Canadian Arctic Archipelago, Baffin Bay and Fram Strait. The transport through Fram Strait is estimated at 533,000 km 2 and 635,000 km 2 for the winter of 2002/03 and 2003/04 which is below the 24-year average of 754,000 km 2 obtained by Kwok et a...

We present a study that explores the affordance evoked by sound and sound-gesture mappings. In order to do this, we make use of a sensor system with minimal form factor in a user study that minimizes cultural association. The present study focuses on understanding how participants describe sounds and gestures produced while playing designed sonic interaction mappings. This approach seeks to mov...

Notesaaz is both a new physical interface meant for musical performance and a proposal for a three-stage process where the controller is used to navigate within a graphical score that on its turn controls the sound generation. It can be seen as a dynamic and understandable way of using dynamic mapping between the sensor input and the sound generation. Furthermore by presenting the graphical sco...

A wireless sensor network that consists of nodes with a sound sensor can be used to obtain context awareness in home environments. However, the limited processing power of wireless nodes offers a challenge when extracting features from the signal, and subsequently, classifying the source. Although multiple papers can be found on different methods of sound classification, none of these are aimed...

Over the last several years, we (all "laptop artists" of this sort) have been active as performers, composers, software/DSP developers and hardware instrument builders. In particular, we have been seeking more compelling physical connections between body and digital sound, creating personalized hardware/sensor interfaces [1] [2], connecting them to custom signal-processing algorithms, and gener...

The paper presents the Kinectofon, an instrument for creating sounds through free-hand interaction in a 3D space. The instrument is based on the RGB and depth image streams retrieved from a Microsoft Kinect sensor device. These two image streams are used to create di↵erent types of motiongrams, which, again, are used as the source material for a sonification process based on inverse FFT. The in...

SpiralSet is a sound toy incorporating game engine software used in conjunction with a spectral synthesis sound engine constructed in Max/MSP/Jitter. SpiralSet was presented as an interactive installation piece at the Sonic Arts Expo 2008, in Brighton, UK. A custom made sensor-based interface is used for control of the system. The user interactions are designed to be quickly accessible in an in...
