More Observations on Hearing Aids

After a full day of using these new aids, a few observations:

In a restaurant where there’s conversation at my table that’s at a normal noise level with quiet background music, these aids seem to pick up best on the background music. Muting one aid appeared to fix this, at least in terms of its ability to create a headache.

Reaction speed seems a little slow — for instance, if Amanda starts talking (and she usually has a quieter voice), I usually have to ask her to repeat what she said. Then again, it was this way with the old aids as well, but these ones don’t seem to do as good a job as the old aids in the second program I had (see previous entry). At least in those, it felt like it was picking up the sound efficiently.

In terms of watching TV, I definitely have to have the volume lower than I used to, but I’ve never been good with picking up speech in a TV show if I don’t have captions enabled on the TV set. Thus, I almost always watch with captions, so this seems to me to be a non-issue.

My statement that this change in aids was less about sound quality than sound control continues to be true, for the most part. I do pick up softer sounds much better (the end of the consonant “S”, for instance), plus some smaller noises I might not have noticed before (my computer keyboards sound louder now). There is the return of a volume control on these aids, but it gives me a very small (about 3dB) range to adjust in. That’s not all that large, but it’s usable. The question is whether or not it’ll allow me to adapt well enough to noisy situations. I didn’t try the volume control in the restaurant today, so that might have actually made a difference. We’re going to Mount Vernon to take Amanda home tomorrow, and we’ll more than likely be having lunch with her father and her sister, so that’ll be another chance to test drive these aids in restaurant environments. Hopefully, my experiences in restaurants, cars, and other louder environments will give me some sort of clue as to what to expect when I return to work and classes in September.

First Impressions of New Hearing Aids

We picked up new hearing aids at a late audiologist appointment today — I’m now “test driving” the Oticon Synchro series of hearing aids, with a fair amount of skepticism involved. If my audiologist is to be believed, she’s quite grateful for my skepticism — says it helps give quantitative feedback about how well the aids really work in particular situations.

Hopefully, that’s not asking too much of me.

Anyway, she asked me to take notes on my experiences with these aids, and I figured it might be worth putting them in my blog so that people might get a glimpse of what it’s like being hearing impaired. It may not work well, but it’s at least an attempt.

Just to explain before I go on: Oticon’s Adapto and Synchro model are both digital, as opposed to analog hearing aids. This gives them far superior sound quality and higher adaptability. It’s exactly like the difference between analog and digital phones — the sound tends to be crisper, cleaner, and more understandable than most older analog devices.

That said, this was a transition from one digital aid to the next, so in terms of the quality of the sound, there wasn’t that big of a leap. The real changes involved in this model switch have more to do with the ability to control sound in a more intelligent way. In the Adapto model (my old aids), the aid can be loaded with two different programs, which usually act in two separate ways. There’s no middle ground — you either use one program or another while the aid is in use. In my case, I had one program which was a noise reduction program, which basically treated any background noise as the enemy and eliminated it. The second program on those aids was more of a broad program, with high volume feed-in that let me pick up a lot more sound with little or no discrimination between what sounds I should or shouldn’t be hearing. The first program was one that I usually used in louder situations — highway travel or walking through a very loud, crowded room, for instance. The second program tended to be the one I used most — though it was only intended for things like lectures, I used it in almost all my everyday conversations in order to ensure that I was getting everything people said.

Of course, hearing aid users (and, dare I say, people with normal hearing) always have a big fear of not hearing things.

Anyway, the Synchro works differently. Now I have up to four programs to choose from, but there are only two currently loaded — a general use program, which is what I’m using for all my hearing, and a telecoil program, which I use with my specially-equipped cell phone. Clearly, I don’t have the option of switching back and forth between programs right now if I encounter a problem, but in some ways, this is better. The single program that I use with the new aids have a much better handle on being able to realistically adapt noise levels based on surroundings. These aids are slanted towards being able to efficiently pick up human speech patterns, and, unlike their predecessors, these new aids can do that just as well whether the person speaking is in front of me or behind me. The old aids had a heavy bias towards picking up speakers that were directly in my line of sight. These new aids, however, while they still have a bias towards line-of-sight speakers, can pick up speech from behind me in much the same manner. I’ve only tested this ability in my audiologist’s office, but I’ll be experimenting with it over the next week or so.

As for the ability to hear on my cell phone, the sound is, as expected, clearer than with the older aids. The only thing that bugs me with these aids so far is that they adapt to current situations based on a set of computed scenarios, then picks whatever volume scenario it thinks is best at the time. I’m in a slightly faster mode than other users of this same aid, but I’m not at the fastest adaptation level that these aids have. I don’t really know if that would help or not.

Of course, aids aren’t the only thing that control how well I hear, but it’s the second most major component. The other major component, since I have behind-the-ear hearing aid models, is the mold that inserts into the ear. I just had these remade, and got new ones fitted along with the old aids, so the sound pickup right now is optimum. That’ll help me test these aids as best as I can.

More later!

Hearing and Web Sites

I had to come back home a day early without Amanda due to a problem with my hearing aids. Despite my troubleshooting of one dead left hearing aid, I apparently missed moisture in one of the tubes, which led to me hurrying back down here and going to the audiologist.

Okay, false alarm, but I was going to go in anyway. Needed new molds made, and I got to hear about some new hearing aid advances, which, of course, is always a subject that gets my attention.

Oticon has released a new model called the Synchro, which is basically one level up from the aids I’m currently using, the Oticon Adapto models. The really big differences here have to do with the way in which the directional microphones on the hearing aids work. On the Adapto, there are really only two ways in which the microphones can work — they can either focus on a narrow amount of noise while still allowing background noise or they can act as a sort of omnidirectional microphone. That limits the Adapto’s ability to — well — adapt to some situations well, since its intelligence is limited to two preset programs stored within the hearing aid itself. With the Synchro, there’s apparently quite a bit more flexibility. Instead of two programs that the aid depends on, the Synchro model does a form of parallel processing, considering several different noise scenarios at once. Based on whatever scenario seems best at the time, it will adjust the volume of the aids to whatever’s most appropriate for that situation. In addition, the Synchro improves on the Adapto’s noise cancellation and feedback cancellation systems, which makes it both better at isolating sounds and better at preventing other people from getting annoyed at hearing aid users because of the whine generated when the aid doesn’t have a tight seal. Both are good things.

Oh, and let’s not forget that a wide selection of colors is available: beige, light brown, dark brown, light gray, dark gray, transparent, yellow, orange, pink, purple, blue, and green. For some, I could see where this would be nice. Personally, I like the clear ones — my audiologist had a display of some of the available colors out.

In addition to that, I’ve been doing some web site work. I’m planning to update the naturalaxis web site with a new layout that depends entirely on CSS (which, I admit, puts me a little behind — there are lots of other sites that have long since gone to CSS-only layout control, but better late than never). I’m also hoping to redo the portfolio section to be more of a case study section on one or two good projects.

In addition, I’m still working with Evergreen’s Web Team and Access Services actively, though progress is a little slow. I’ve also thrown together an informational web site for the Enrollment Growth DTF, which I’m serving on for the duration of the academic year — it has yet to be approved, so, thus, has not been posted.

I’m looking forward to seeing my good friend in Port Townsend. It should be a good weekend.
