@dubh You have a Ph.D?
@PawelK For that use it would be better to use a microphone in the ear as the ear does a filtering of its own by shape. It's pretty cool that we have an optimized baffle and amplification system made from cartridge and skin.
@PawelK The microphones would ideally be near the mouth and one farther from the mouth. This would allow for a better filtering of ambient noise near the main microphone. The rationale is that each channel would have a stronger audio section with a smaller section. The two different channels would contain nearly identical sections but they would opposite in magnitude.
The main microphone will be the primary sensor and the secondary microphone would be for filtering. The wave shapes would be the same. It would just be a simple sample and remove for the audio signal to gain a lot of clarity.
@PawelK Yes, a system could be developed around the technology. Ideally one would want at least two microphones to sample and send to a capable MCU. This would allow for better filtering and more features. There would be a delay but it would be minimal. Two inputs with a simple algorithm for the average of the two signals. This could be sent to the output for a delay that would be the sum of the distance traveled + Cycles + the reaction time of the mechanism. It would likely be a few milliseconds. The M5STICK would be capable of this and the wireless connection.
@PawelK @yukiame The most difficult part would be getting the replacement to pass regulations. The rest of the system would be rather easy to implement.
Something like a Throttle Body Fuel Injection system would be easy to retrofit to older vehicles. There's the Holly EFI system that does this for around $5,000.
@PawelK @yukiame It had good fuel economy too. I do have training as an Automotive Technician and I've worked on heavy equipment for most of my life. The electronics used on board modern vehicles are what I despise most. I would be very open to replacing the black boxes with something open source and open hardware.
@a_breakin_glass @tk Fuel cells are still not feasible for nearly any application on earth. The only fuel cell that I know of that worked well was a hydrogen fuel cell that NASA used in space.
