DIY ALD from off the shelf parts
I think its possible to create not only a very competitive ALD (assisitive listening device), but also a hearing aid system from off the shelf parts as well. In other words you make your own system. I believe a simple system can now be built by people that are not electrical engineers or similar.
I think a parts list could be assembeled such that even non tech people can purchase and use.
Rough estimates - good hearing aids run about $3000 each. A device like a Zoomlink runs about $1500. So thats roughly $7500 for a system that will be obsolete in 2 or 3 years.
I think we should attempt to make something simple to give people an option. Maybe this will fizzle out to nothing, or maybe it will take off and be useful and developed, or maybe its already been done by others a thousand times I dont know.
I got inspired my what Musick7 did, except it looks like he is high tech capable, I am not so much. Also he is doing the processing inside his hearing aid which is a principal I dont want to follow. I want the processing done outside the hearing aids to free the hearing system from the #1 bottleneck and limitation of hearing aids -Processing power which which is limited by available battery power.
I would like to start very simple and follow the KISS design idea (keep it simple stupid). Its possible that even trying to build a very simple system involves problems that will essentially impossible for the layman to oversome.
I would be nice if others would buy the parts too, utilizing the ideas here or thier own ideas, but at least provide your gained knowledge here for others to benefit from. I purchasd some items on Amazon last night and they are being shipped out. Its my attempt to piece together a very simple starting system that uses bluetooth, cost so far is $128. Many of these parts can be used for other things so service a dual purpose which is nice. I have to run now but will be back later today.
