Hi All,
I've just about finished up building a prototype bone conduction hearing-aid system. At the moment is consists of a pair of mics, mic pre-amps, 5 watt amplifier and bone conduction transducers. I have single-sided deafness and a hearing deficit in the good ear (age related). This thing allows me to hear things from the deaf side (the "sound shadow") for the first time in a couple of decades. Commercially made bone conduction systems for hearing impairment are outrageously expensive, and not covered by my insurance. Once I've got this dialed in I hope to offer it to others as a low cost alternative.
I've worked with Teensy before and I've reviewed the great stuff available for audio projects. I want to add digital EQ to allow adjusting the system to a hearing profile, along with providing other digital enhancements. It looks like 7 channels of EQ are available and that should suffice. I need advice about latency, however. Is the Teensy (with the audio adapter) going to be fast enough to avoid noticeable latency? In other words, it's confusing to see a speaker forming words and hearing those words with noticeable latency.
Thanks.
