Research in sound source localization and quantification using phased arrays, in particular,

  • beamforming techniques / algorithms
  • applications of beamforming systems
  • machine-learning methods
  • intensity analysis
  • holography / inverse methods
  • measurements of fly-over noise
  • combined / related methods


The objective of the conference is to contribute to the development of beamforming methods with respect to the localization and quantification of sound sources. In addition, the conference provides a platform for the presentation and discussion of practical results from a wide range of specific implementations.

Beamforming with microphone arrays and related techniques have become standard methods in technical acoustics, proven by an ever increasing number of publications at various acoustic conferences. The methods are used in the highly complex field of aero-acoustics, for the sound source localization on moving vehicles, in technical plants and machinery including the automotive industry. A number of companies are offering commercial beamforming systems. At the same time, a large variety of implementations exist in the academic sector as well as tailor-made solutions for special applications. In order to improve the quantitative analysis of the source distributions, inverse methods are becoming increasingly popular.

BeBeC provides a forum for a vivid exchange of experiences and opinions. Both theoretical and practical work receive a platform. Competing institutions and companies are encouraged to participate. Comparisons with other acoustic methods are welcome.
