Hello David,
the open-source software platform "open Master Hearing Aid"
(openMHA, www.openmha.org) includes a solution that you might find
helpful.
A Matlab/Octave fitting tool is available that performs offline
processing of .wav files using openMHA, several audiogram-based
prescription rules are available and own own can be implemented in
Matlab/Octave.
https://github.com/HoerTech-gGmbH/openMHA/blob/master/mha/tools/mfiles/mhagui_fitting_offline.m
In terms of commercial gain prescription rules, openMHA supports NAL-NL2 and DSL v5
See
https://github.com/HoerTech-gGmbH/openMHA/blob/master/README_NALNL2.md
https://github.com/HoerTech-gGmbH/openMHA/blob/master/README_DSLmio5.md
for details.
In case of questions, the openMHA user forum is a good place to
ask:

Best,
Hendrik
ACHTUNG! Diese E-Mail kommt von Extern! WARNING! This email originated off-campus.
I am hoping to get some advice on presenting stimuli to hearing aid users for an experiment. The goal is to present stimuli to hearing aid users directly from a PC via insert headphones. We would like to ask if pre-processed signal “A” is better than pre-processed signal “B”, with each sound consisting of a .wav file. To present the signals, we would like to pre-process the wav files for each listener based on their audiogram using a reasonable hearing aid prescription, such as (but not necessarily) NAL-NL2.
How do I pre-process these wav files? Is there a software tool available where I can provide an audiogram and a wav file and it will output such a file? Could somebody point me to such a tool? A free solution would be preferred, but I would appreciate learning about any solution.
Any help / pointers would be greatly appreciated.
Thanks,
David
