NURA AND EVEN--- DISCUSS ??!

Interesting. Wonder what they do for someone with medium to sever hearing loss.

Even sounds like it would probably work, in that it looks like it actually sets a built in equalizer based on the user's subjective hearing response using what is basically an audiogram. Someone with tinnitus or sensorineural loss is going to be able to adjust for best performance, as is someone with conductive hearing loss or otosclerosis. I am surprised this was not introduced as a smartphone app controlling an equalizer in the phone instead given that many people will be listening that way anyhow. This is like a tuned hearing aid, or like a stereo set with a graphic equalizer--established workable technology in a new package.
 
Nura, on the other hand, depends on their version of otoacoustic emission, which is commonly used to test newborn hearing, where it will not produce a reliable frequency band test, and probably is not going to do what they think it will here. There are so many factors affecting the reception of these inner ear sounds at the canal, that it is doubtful they could produce anything close to the use of an equalizer tuned to subjective responses even in a totally "normal" listener. Still it sound like a great magical/scientific breakthrough. Who can argue with that?
