Interesting! Do sounds and voices played through that headphone jack sound higher quality than sounds picked up by the local microphone and relayed to you? What's the frequency range that you can pick up with it? Can you hear sounds >20kHz or <20Hz?
Also, 2.5mm (like old headsets) or 3.5mm (like standard headphones)?
When I said "local microphone", I just meant the microphone that picks up local sounds, as opposed to anything you might plug into the headphone jack.
Thanks for the explanation; very interesting.
Have you considered testing the frequency response of both options? See http://www.engr.uky.edu/~donohue/audio/fsear.html for test sound files. You could play those files via speakers and via the headphone jack, and see if you get drastically different results for certain frequencies.
I too have a cochlear implant with the 2.5mm jack adapter, and I actually prefer headphones to the jack adapter, mostly because the color of the sound seems to be a lot better with headphones than the 2.5mm jack - the direct audio signal seems harsh and not warm. I listen to a lot of classical rock, and this may be part of the reason, it just seems to translate better over headphones than direct input.
I have a cochlear implant and I've had several of these audio induction loop tidbits for my CI processor (hearing aid) for years. In my opinion, the wire is a PITA and attracts a lot of attention.
This spring, Advanced Bionics is coming out with a bluetooth-enabled CI processor so that I finally can be able to listen to music on my smartphone via bluetooth without having to deal with wires. I've already got the money waiting to reserve myself one of these processors.
I know there's a part in the ear called the cochlea but I thought the company just added the letter r to the word and made that their name; I didn't know the word existed before the company. Thanks!
I am not sure whether it is due to any technological limitations in Telecoil or a $400 Telecoil would work as good as this, but I'll be sticking with my headphones for now. :)
Another alternative is to get top of the line hearing aids and pair them up with an FM transmitter (I have a Nadia and a Smartlink+ http://www.phonak.com/com/b2c/en/products/fm/transmitters.ht...). Once again, average sound quality for music but you can pair the transmitter to your phone using Bluebooth. True handsfree.
When I've used my hearing aids with phones, I've always had the impression that the audio quality is pretty bad. Telecoils apparently go back to 1947, and so it wouldn't surprise me if they were relatively poor quality either for efficiency or simply because it was the state-of-the-art back then (or the quality was limited by some other system - why have higher quality than a telephone can deliver?).
Have you ever used high quality ear buds? I'm curious how they compare to either telecoil or over-the-hearing aid headphones. I have a fairly pricey (~$150) set of etymotics that I use and they sound fantastic to me (moderate/moderate-severe hl). I also suspect they give me better ambient noise isolation than using Telecoil with my HA would.
I have tried (both cheap and high quality) ear buds and they don't really work for me. I can barely hear the music despite turning the volume of the source to full (probably because I have severe hearing loss). I haven't tried custom fit ear moulds yet, but I guess they would be just slightly better. Basically, I need the amplification that my hearing aids provide to listen to music.
A good set of headphones will likely have better bass response than a hearing aid. For low frequencies, perhaps you're actually hearing them through the vent and not the hearing aid at all? If so, no fancy wireless connection will do as well.
I'm actually stone deaf at high frequency (I cannot hear a 'sh' sound, even with hearing aids) but have some amount of hearing at low frequency. It is possible that I'm hearing partially through my ear vent with the headphones but the hearing aids definitely assist.
My problem is that my conductive hearing is crap but my nerve hearing is great. Doctor and audiologist recommend putting a screw into my skull to attach one of those bulky bone-conductive hearing aids so I hear everything through the nerves. I don't like the idea because they are big and apparently not shrinkable, and because they basically make everything mono. Not sure if there's other tech that is a better alternative?
I have two BAHAs (bone-assisted hearing aids). Up until a few months ago, I had only one and yes - stereo hearing was not great, but hearing well in mono was better than not hearing well in stereo. I now have one on each side and do have some stereo hearing now.
As far as "bigness" I guess you just have to weigh the ability to hear verses vanity and getting a few stares now and then.
I've had hearing aids for 20+ years. I occasionally try the tele-coil in locations that have them. I am always disappointed; the quality is just not there. It sounds (haha) like the OP didn't have a very good audiologist, one that did not go through the full range of options with him.
It's also possible that my loss is not severe enough to be satisfied with the tinny tele-coil quality.
I believe the tele-coil technology was developed to enable the use of phones with hearing aids. The aid, when used with an old-style phone held in a normal position, is close enough to pick up the magnetic field directly from the handset speaker. Not very useful for today's phones though.
Just like mvleming, I use a bilateral personal audio cable that jacks into my processors directly.
There are two major things wrong with the post:
1) "Nobody else can hear it" - Well, no, when I was listening to music with my hearing aids (Before I got my implants), well, even the best seal on 130db music can't prevent some of it leaking out of your ear and annoying your coworkers.
2) Induction loops are extremely prone to interference. There are many buildings in which Telecoil mode gets you really raw static noise. On airplanes, it's intolerably loud - you can't use induction loops on airplanes. At all.
I've had a double stapedectomy (replacing the stapes bone with a metal prosthesis) and I can't tell the difference between a $400 pair of headphones versus $100, but I can tell a difference on the low end. As my hearing is likely to degrade, this will be of interest when need to get hearing aids.
An honest question: I've always referred to this condition as being "hard of hearing" but the author implies that it's impolite to call it as such. Is there a better term that we should be using?
It's just stupid though. Some people get offended by (for example) "hearing impairment" because... it's implying they have an impairment. You do have an impairment, jeez.
It's different in groups too. I believe if you're profoundly deaf, and you sign and actively involved in the "deaf community", you're Deaf. If you're not, you're deaf. Maybe I have that backwards, but I don't really care.
There is no safe term. Over here where I live 'deaf' is politically incorrect and 'hearing impaired' is the politically correct word. 'Hard of hearing' usually implies that you're old and therefore, have low to moderate hearing loss.
When I was in USA, 'hearing impaired' was politically incorrect (responses to an post on a HLAA mailing list where I used 'hearing impairment' made that clear). The PC word is 'hard of hearing' or 'deaf'. As far as I can use, those who belong to the 'deaf culture' (i.e. use sign language as their main means of communication) prefer to call themselves 'deaf' whereas others who use hearing aids or cochlear implants decide to call themselves 'hard of hearing' or 'hearing impaired'.
I don't really care either way which term you use. It is more how to use it - i.e. you shouldn't use any of these terms to derogate or mock hard of hearing/hearing impaired/deaf people.
This is the impression I've gotten. People try to be sensitive or PC with good intentions, but there's a lot of awkwardness still. Just seeing the replies to my question show that there doesn't seem to be a consensus for specific terms, but your advice to simply 'stay classy' seems to be the way to go.
