Ask Slashdot: Hearing Aids That Directly Connect To Smart Phones?

mtcups writes "I am a musician/IT guy whose hearing has suffered from VERY LOUD guitar players, (yes I do use earplugs now, but too late), and am faced with the outrageously priced hearing aids $4.5K+/pair and was appalled at their lack of integration with smart phones. It seems obvious to me that I should be able to control the hearing aids via a smart phone interface so I can shape the profile for different environments, and also control features like 'hearing loops' and Bluetooth connections. I have done some research, but my guess is that the hearing aid companies want proprietary systems and don't want a smartphone interface since they would loose control and it would allow for competition for cheaper & better programs. I am not convinced that a combination of good ear-buds, good microphone(s), and a smartphone interface couldn't totally replace these overpriced solutions."

Re:You're right, it's a racket

If it's just a racket, why not buy the cheap hearing aids you see advertised all over the place? Less than $200 each.

I'll tell you why: because they're crap. They uniformly amplify the entire sound spectrum, which means that sounds in the range of your hearing that are not impaired, driving you crazy with feedback and overamplification. Real hearing aids selectively amplify the frequencies you need. Mine (which I only paid $2k for) don't actually make sound like they're amplifying sound, more like restoring missing texture.

Mine not only contain sophisticated DSP hardware, they have small radios so they can talk to each other and work together. If you think you can build something like that for less than $1K a unit (which also has to cover the cost of fitting and programming) then go for it.

I use Phonak hearing aids, they have an external Bluetooth gateway called iCom which is an small box with an induction loop you have to wear as a necklace. The sound quality is very good when using the phone and both hearing aids are in usage when using the Bluetooth link. This is a big plus in my case since my capability to decipher the spoken language increase significantly when using both ears vs any single ear.

As mentioned, the reason the external box is required (in fact it is almost a battery only) is the required power would drain your hearing aids batteries very quickly if you have to power the Bluetooth chip.

However, with the new BT v4 low-power for medical devices, it is likely this will change in the few next years as the manufacturer will incorporate the new BT chip and convert to the new standard.

The necklace type gateways are better than nothing, however the design could have been much better. In the case the Phonak device, the material the wire was covered with harden with the time and eventually the wire simply break by lack of flexibility at the junction with the plug. I had to replace it at least once a year and the replacement cannot be done by the customer, that means you have to send the box to the company and be deprived of it for about a week. This should have been made field replaceable. At least the audioprothesist could have done the replacement without delay.
