In the following figure, the loudspeakers are denoted by square markers. Three directivity plots (with a linear scale, which is different from logarithmic scale or the human hearing scale) are shown for three different beams directed at various angles. These directivity patterns are computed for 220Hz.</span><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgT3cXPjusjyUkJHQc87zou3CE8DfOXGPFA1HKmNW1OyKd1IwECIxrppAPkSJGRSD12p_3TMlNprHqDf2YSCgXB-0QEhAiAcLhxCkXabhGPU9PJMjsBxpoMhDw-4ECxFUbjQbrVbe-77O-D/s1600-h/directivity.bmp"><img style="margin: 0px auto 10px; display: block; text-align: center; cursor: pointer;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgT3cXPjusjyUkJHQc87zou3CE8DfOXGPFA1HKmNW1OyKd1IwECIxrppAPkSJGRSD12p_3TMlNprHqDf2YSCgXB-0QEhAiAcLhxCkXabhGPU9PJMjsBxpoMhDw-4ECxFUbjQbrVbe-77O-D/s320/directivity.bmp" alt="" id="BLOGGER_PHOTO_ID_5101951526911061202" border="0" /></a><br /><br /><span style="font-family:arial;">The following figures presents a beam in an horizontal plane.

The artists created a compact loudspeaker array for acoustical beam forming as a spatial sound platform. Using the array and specifically created Pure-Data pacthes, the hyperdirective sound beams can be steered at various angles from the loudspeaker array. The two sound artists work and explore the notions of public and private auditory spheres while producing private listening areas using the sound beams. Locally projecting a sound, a voice as an example, as it is the case for these “Auditory Tactics”, in a space populated by moving noises and voices, is connected to the general and common strategy of listening delimitation (the cut of of a private sphere, possibly secret, in public spheres, communicative). Such sound projection techniques, soon passing in the real world, will contribute to the general reconstruction process of listening and speech, auditory practices and strategies, as cultural fashionable objects. With the intentions of questionning such issues, the artists created a sound composition based on interaction with the public, fragment of altered, cutted and transformed voice samples, as marks that put communication technologies on spoken and listened language as a cultural, plastic product. The main intention is then to explore and engage the social and human evocations, behind the technological possibilities, of beam forming and new spatial sound technologies in the social field. The artists acknowledge Yann Pasco for the fabrication of the loudspeaker array.Philippe-Aubert Gauthierhttp://www.blogger.com/profile/03748411047236584819noreply@blogger.com0tag:blogger.com,1999:blog-4422649460039261047.post-67767397618398621262007-07-23T06:47:00.000-07:002007-07-23T06:55:36.578-07:00Presenting "Auditory Tactics"Invited for an artist residency at Vidéographe (Montréal, Canada), Philippe Pasquier and Philippe-Aubert Gauthier decide to create an interactive sound installation based on compact loudspeaker array and beam forming.
