abstract = {Localization of acoustic sources is a powerful tool in different applications,
for example, in quality assurance by locating the source of noise created by
a machine or locating a person calling for help in ambient assisted living environments.
This paper presents the first steps in the localizeIT project for acoustic
source localization by simulation and comparison of different microphone array
geometries to determine their effect on the localization performance. The time difference
of arrival (TDOA) is used in the acoustic source localization method. The
TDOA is estimated through an approximation of the phase shift of different signals
calculated with the cross correlation operation. In order to find a good arrangement
of microphones, a simulation is performed to compare different microphone
arrangements for the presented localization method, with regard to the available
space in a typical indoor environment. Those different microphone arrangements
are classified into two categories: compact measuring stations positioned inside
the monitored area, and larger satellite systems with microphones surrounding the
monitored area. In the simulated scenario, the large satellite systems are superior
to the compact measuring stations using the same number of microphones. Comparing
different compact systems the results suggest, that the arrangement has a
measurable and practical influence on the precision of the system.},
