Geometric inference of the room geometry under temperature variations

Paolo Annibale, Jason Filos, Patrick A. Naylor, Rudolf Rabenstein
2012 2012 5th International Symposium on Communications, Control and Signal Processing  
This manuscript shows how to use the geometric inference jointly with the speed of sound estimation for a more accurate reflector localization.  ...  It is based on a simple observation that turns time differences of arrival (TDOA) or time of arrival (TOA) measurements from the signals of a microphone array into a geometric constraint.  ...  Accurately estimating the speed of sound is therefore highly desired. Geometric inference is an approach for localizing reflectors in a closed acoustic space [2, 3, 4] .  ...

Array steered response time-alignment for propagation delay compensation for acoustic localization

Pasi Pertila
2008 2008 42nd Asilomar Conference on Signals, Systems and Computers  
However, in the atmosphere the propagation delay from source to array is typically significant, causing true source position and the estimated direction to differ.  ...  Locating a source using direction estimates from spatially separated microphone arrays has been widely researched.  ...  Acoustical DOA observations from arrays appear to follow the true source position due to propagation delay. This biases localization.  ...
