How can i deploy software developed in MATLAB / Simulink in a physical Hearing Aid ?

Good evening, i'm a software engineer student. I'm working on a project that amplifies human voice and reduces noises with some configurations.

I wish to know if it's possible to deploy this into a physical hearing aid and how could i do this? I'm a begineer in this field but i need some kind of confirmation that its possible for my teammates.

Hi Jorge,

I see that you want to know more about deploying code to a physical hearing aid. Since this is not a trivial task, & requires multiple steps. Here is a high level overview of how you may go about it:

Prototype Your Algorithm

• Refine your model in MATLAB/Simulink.
• Convert algorithms to fixed-point arithmetic using Fixed-Point Designer.

Select Suitable DSP Hardware

• Choose the appropriate Digital Signal Processor (DSP) chip for your hearing aid.
• Obtain a development kit for the selected DSP.

Code Generation and Optimization

• Use MATLAB Coder and Simulink Coder to generate C/C++ code.
• Optimize the generated code for the DSP architecture.

Software Integration

• Familiarize with the DSP’s firmware development environment.
• Integrate MATLAB-generated code with DSP firmware, adapting for hardware components like ADCs (Analog to Digital Converter) for microphone inputand DACs (Digital to Analog Converter) for speaker output.

Testing and Validation

• Deploy and test the firmware on the DSP development kit.
• Refine algorithm and DSP code based on testing results.
• Deploy & Test.
