I have as time goes <br />on become inured to this, but knowing a bit about DSP and a lot about electronics, <br />I have been on a quest to see just what is inside the device and why it is worth upwards of $2K bucks each.<br /><br />I have had no success whatever in getting technical details from anyone. Vendor data is always<br />"It'll make you hear better" or "It'll make you cuter" or "it'll cut out noise (a lie)". junk like that. <br />Discussion with my audiologist has been a bit helpful; she understands what I am looking <br />for, but has the same inability to get concrete data. Discussion with "the hearing aid guy down the street"<br />is worse than useless.<br /><br />Is there anyone out there that has some idea of just what is inside my ITE hearing aid?<br />I presently use a pair of GN Resound Canta 4's.<br /><br />Any help or advice would be appreciated. <br /><br /></p>
