Availability of the first version of the openMHA - an open community software platform for hearing aid research (funded by NIDCD 1R01DC015429-01)
The open Master Hearing Aid (openMHA) provides researchers with the means to efficiently develop and evaluate, in collaborative multi center environments, novel signal processing schemes, individualized fitting procedures, technical solutions and services for hearing devices such as hearing aids and assistive listening devices. The open-source platform comprises of the following components:
-
A software development kit (C/C++ SDK) including an extensive signal processing library for algorithm development and a set of Matlab-/Octave-compatible tools to support development and offline testing.
-
Real-time runtime environments for standard PC platforms with standard sound hardware (Linux operating systems) as well as ARM platforms (e.g., Beaglebone black).
-
A set of baseline reference algorithms that forms a complete hearing system (multi-band dynamic compression and amplification, directional microphones, binaural beamformers and coherence filter, single-channel noise reduction, feedback control)
Documentation is available for three types of users: Algorithm developers who want to program own signal processing blocks (“plugins”), system engineers who want to set up a HW/SW systems for experiments with the openMHA and want to customize and configure the signal processing blocks and audiologists who want to test and individually fit a basic hearing aid system out of the box.
