As is known, the traditional approaches to realize acoustic directional sensing require a microphone array combined with a localization algorithm [7]. The fatal drawbacks of such approaches are the requirement of multiple microphones and complex signal processing algorithms. In order to break though ...
2. A hearing aid according to claim 1 wherein said predefined criterion comprises a minimization of a difference or distance measure between the resulting transfer function Hpinna(θ, φ, r, k) and the transfer function HITE(θ, φ, r, k) of the microphone located close to or in the ea...
For example, TCE 115 may use an array as a basic element, where the array may not require dimensioning. In addition, TCE 115 may be adapted to perform matrix and/or vector formulations that can be used for data analysis, data visualization, application development, simulation, modeling, ...
