Are you a NHS digital hearing aid user or know someone who is?
My wife has been fitted with 2 and has great difficulty with hearing
telephone conversations. I believe there is a way to use the 'T'
setting, how and what do we need?

Go back to whoever fitted them. God knows why you posted this to a
Television group. If you know it is off-topic why even post? Do you turn
to a
completely unrelated newsgroup each time you lack common sense?

But the thread turned out interesting despite your protestations.

Ohh, our Katie was christened in the local happy clappy. It was quite an
interesting event.

Not sure about the 'happy clappy' but why be miserable, guess the others not
get many there.

I'm losing track of the thread... You want a small loop system for one
room in your house? A complete kit is available from CPC for £115.50 (inc
VAT).

They also have a range of other amps and bits look under: Audio, Video &
TV PA, Disco & Musical Equipment Assistive Hearing Products.

If you have a spare mono audio amplifier of say 20 to 30W RMS that could
be a DIY solution with a bit of multicore cable(*) laid around the room
and wired to form a few turns. What you will be missing is the compressor
that dedicated loop amps have to reduce the dynamic range. Loops need to
be driven to work well, small signals produce low loop currents thus don't
couple so well to the receiver.

(*) Choose something without any twists or pairs, alarm cable say or flat
telephone extension cable.

Loops take quite a bit of drive, several amps, so a few transients of
(hopefully) surpressed triac buzz are not significant. What can be
problematical is the power current flowing from the dimmers to the lamps
and back. Normally the live and neutral are in the same cable from dimmer
to lamp thus the field from each conductor more or less cancels out but if
it becomes possible for the paths to become separate then you get a nice
50Hz loop formed. Ring mains with a break in either live or neutral (but
not both) can do it as the ring becomes unbalanced.

Talking loops in a Church if she uses the 'T' loop she only gets the
voice and not the music so does not use the loop there. Sounds to me
only speech passes through it and not the music.

That's the fault of the church for not putting a music feed through. They
should have a separate mix for the inductive loop to enable music and the
congregation singing to go into the loop.

Yes I would think that the wireless tie mic. could well be the one feeding
the loop.
She does have no problems listening to normal PA which we are of course
listening too.
I would think the Church PA guys have plenty on without a second mixer for
this loop to operator as well. The PA system and the computer to put
words on to a screen via a projector.

Well there was this, which may not have been reported your side the

A good place for a simple voice/music control for the loop would be at the
organ console. Almost everything else can be preset or ALC.



Organ you mean one of those pipe things?

No Churches have music groups from 2 or 3 musicians up to a full band
complete with Singers. Hence they have large mixing deck for PA.

My church has "one of those pipe things", and a choir of which I am a
member. We'd be horrified if a microphone was used when we were
singing. But the church has a PA, strictly for speech, levels preset.

High wattage dimmed lighting can cause problems (due to switching
transients on each mains cycle) for hearing aids on the T position.

Shouldn't do hearing aids respond to a varying magnetic field not an RF
one from dimmers. What can be a problem is inadvertant mains loops
producing hum.

The instance I'm thinking of has the dimmer switches at the front of
the church, and the lighting wiring at ceiling level all the way to the
back of the church. Triac-based dimmers clip each edge of the mains
waveform even when fully on, producing magnetic fields in the wiring at
50Hz, 150Hz, 300Hz, 450Hz, etc. Hearing aids will probably roll off
anything under 100Hz anyway to avoid picking up mains hum, but the
higher harmonics will get through.

I was under the impression that modern dimmers used zero-crossing
switching (presumably involving microprocessor, or at least something a
bit more complicated than the conventional). Though this won't help
existing systems.
