The goal of OpenMHA is to transform the HörTech Master Hearing Aid into an open source software platform for R&D purposes. The platform consists of three main elements:

  • a software development kit (C/C++ SDK) including an extensive signal processing  library for algorithm development and a set of Matlab and Octave tools to support development and offline testing
  • real-time runtime environments for standard PC platforms (Windows and Linux) as well as mobile ARM platforms
  • a set of baseline reference algorithms that forms a complete hearing system (multi-band dynamic compression and amplification, directional microphones,  binaural beamformers and coherence filters, single-channel noise reduction, feedback control)
