The Sony MDR-XD100 works fine with my aids, the MDR-CD60 set that I have
produce feedback - the cutout in the foam is more of an oval in the MDR-CD60 while the MDR-XD100 has a full circle cutout - I think that is the major difference. I would think there is a big dependency on the gain of the aids at any one frequency, so my experience may not be applicable to others. 73, Don W3FPR On 8/8/2013 2:55 AM, Jim Brown wrote: > On 8/7/2013 7:20 PM, Don Wilhelm wrote: >> I have one Sony headphones that work fine (large earpieces) > > Which Sonys work? > > Jim > ______________________________________________________________ > Elecraft mailing list > Home: http://mailman.qth.net/mailman/listinfo/elecraft > Help: http://mailman.qth.net/mmfaq.htm > Post: mailto:[hidden email] > > This list hosted by: http://www.qsl.net > Please help support this email list: http://www.qsl.net/donate.html > ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |

well for those of you who are looking into hearing aids and other devices.
this is the one I have http://www.medel.com/us/children-soundbridge-the-vsb/?PHPSESSID=b4l2g37cmsmuin0m5j7pitc6g3& I was looking for a bluetooth to telecoil conversion . that would work with my kx3 so I dont have to jack in all the time.. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |

Most of the recent Hearing Aids have something called T Coil or similar
feature. Very popular in Europe where folks gather like churches, etc. its essentially an inductive pickup. The idea being a wire loop is run around the room parameter and a few watts of audio is pumped through it. Any hearing aid with T Coil inside the loop will pickup the audio by induction. I haven't tired it yet but was thinking of running a loop or coil around the operating desk and feed it with a couple audio watts via a small amplifier module and the K3 line out. Would be interested in hearing any results. BTW - A Google will get you lots of T Coil hits. 73 Bob W7AVK On 8/8/2013 6:09 AM, Richard Neese wrote: > On 8/8/2013 9:06 AM, Richard Neese wrote: >> well for those of you who are looking into hearing aids and other >> devices. >> >> this is the one I have >> http://www.medel.com/us/children-soundbridge-the-vsb/?PHPSESSID=b4l2g37cmsmuin0m5j7pitc6g3& >> >> I was looking for a bluetooth to telecoil conversion . that would >> work with my kx3 so I dont have to jack in all the time.. >> > I ment to say this is the one I am looking at getting... ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |

Yes, it is, but it has never gained traction in the US, where virtually all systems for the hearing impaired use RF or infrared. I've used both successfully in some pretty big spaces, but prefer IR for most venues. The Achilles Heel of these systems is stray magnetic fields, which can add 60 Hz hum to your hearing aid. Two common sources of stray 60 Hz fields -- the transformers in big power supplies, and wiring errors in the power system, the most common of which are mis-wired outlets and double-blonded neutrals. Most of us have power transformers somewhere near our operating desk, and wiring errors are common (houses are wired by human beings, and we, as a species, make mistakes). :) Modern hearing aids are built around microphones and chips specifically designed for that purpose, with lots of equalization and other signal processing that can be tweaked to compensate for each individual's hearing loss. Engineers from Etymotic Research, a major manufacturer of both the chips and the microphones, was quite active in the Chicago Section of the Audio Engineering Society, and gave a couple very interesting presentations to our meetings about the microphones, the chips, and the systems as a whole. I don't know which brands of hearing aids use their components. About ten years ago, they hired the engineer from Shure who designed the very popular SM-58 mic. Last I heard, he was working on directional mics for them. A well-designed hearing aid should roll off the low end on T-coil inputs to minimize this, but I don't know if they do or not. Perhaps someone who is using it (or has tried it) can comment. Another comment. Hearing aids are very expensive in the US (I hear $5K-$6K being typical), and I strongly suspect that it is the result of limited distribution contracts between audiologists and the manufacturers to protect the high markups. Costco's prices are about half that, but they tend to be well rated, and W6OAT is VERY pleased with his. I also saw/heard a piece on either NPR or PBS a month or so ago about a guy who is developing a low cost hearing aid that he intends to sell in the $600 range. It's less sophisticated than the others, with fewer adjustments. 73, Jim K9YC ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |

Given the processing power of the modern smart phone I wonder someone hasn't
developed and application to use regular ear pieces and sample sounds to set it all up yourself. David G3UNA > > Another comment.

Note to Steve KS6PD:
If you suspect hearing loss get your hearing tested by a professional audiologist. You may benefit from hearing aids, now! Perhaps your employer provides annual physicals which include hearing tests? That should tell you. Donald K6RV sent me more info on the Phonac ComPilot, so I will check with my audiologist on it. It would be handy to use with my K3 or KX3, plus answer the phone anywhere in the house. Mark KE6BB story was funny but not far off the mark. Too often hearing loss is not recognized and the individual not identified as having a handicap. There is no outward sign that one is hard of hearing: no missing limbs, no white cane, no service dog! My headphones are old: Sony DR-V600 (not sure they are made anymore). I have T-coil enabled in my hearing aids but I find it not very useful (worse than using the speaker phone) and did not work with some office phones. 73, Ed - KL7UW http://www.kl7uw.com [hidden email] "Kits made by KL7UW" ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |

In large spaces I sometimes use one hearing aid on the T-coil setting while the other is receiving the room in the normal way. This gives very useful "diversity reception". When listening to a single person speaking, the T-coil system often gives the more intelligible signal because it receives a direct feed from the podium or lapel microphone, unaffected by room acoustics. >The Achilles Heel of these systems is stray magnetic fields, which can add 60 >Hz hum to your hearing aid. Further problems arise from the non-uniform magnetic field from the large induction loop. Listeners sometimes have to orient their heads in odd-looking ways to achieve a usable signal, while in high-signal areas there is also a risk of unexpected feedback from musical instruments that have magnetic pickups. 73 from Ian GM3SEK ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |
