Been in touch with two hearing services, and all they could say was come in for a hearing check, hoping to sell hearing aids. My question to them was how was, how come I can hear conversation, (I am extremely deaf and wear aids), I can through my hearing loop around my neck, via blue tooth to the TV, hear speech from the TV perfectly, but I cannot hear via normal listening through my hearing aids the dialogue from the TV or sound bar speakers.
Have been looking into this and apparently sound is now transmitted using five full bandwidth channels and one low-frequency effects channel. Dolby Digital, Dolby Pro Logic II, DTS, and SDDS are all commonly 5.1 systems. From what I can understand, with surround sound systems, the signal is directed through a decoder, the picture signal is sent to the TV, and the 5 sound channels sent to the 6 speakers, The 3rd speaker (middle, center) handles the dialogue, the rest including the .1 speaker the woofer handle associated sounds.
It looks like a good quality decoder will allow the volume of the various speakers to be adjusted, so the middle or center speaker can be increased in volume so persons with hearing problems could hear the speech. I had a search on Facebook and found a thread about people having a hard time hearing the TV, varying comments, but what surprised me was there was over 800 replies from people having a difficulty in hearing on just this one thread.
My question is, if what I have written above is correct, what happens to the signal, if it is routed into the TV first, will the output audio signal via HDMI or optical, still have the 5 channels, and can they still be separated. I ask this because sound bars take their signal from the TV via the HDMI or optical source, most don't have any means of increasing the volume of the 3rd or middle speaker.
I don't expect any or many replies on this thread, but there maybe one or two of you that can add a comment thankyou. Ian

My answer is... I don't know.
When I sold my house four years past I still had a CRT TV on the basis that even if you watch it on a 72" TV with surround sound crap is still crap and there is very little in the world of TV/film which interests me.
I suspect the people on that forum will be able to answer your questing in mind numbing detail :)

I also don't know.
But probably the sound equivalent of TV (pre digital). You can always watch a BW signal on a colour TV with the L (luminance) channel. If you then wanted to see a more complex image, colour, then you need the A & B channels.
Using LAB for sharpening & blurring in image processing is far better the using RGB.
So I am sure audio has something similar.

The only thing we know is that free to air is rapidly degrading in sound quality, unmonitored crap in reality, particularly on secondary channels, maybe the 99th repeat has run out of sound. But normal for us is 22 , the other night we got to 30 on a bit of an old repeat which we had missed, so bad we hit the off button.
That may help insofar, dont spend too much.

It is! In the normal operation of any TV, that is, receiving free-to-air broadcasts, both the picture and the sound are processed by the TV.
Do you have your sound bar connected direct to a satellite receiver or Foxtel box? If yes, have you tried connecting the sound bar directly to your TV?
On most modern TVs, you can choose one of a number of audio style selections such as movies, sports, music, news and more (the news option providing the clearest sound for dialogue) as well as enabling or disabling surround sound, Dolby 5 and auto sound levelling.
On my Hitachi TV, all audio options are available for both normal TV reception and when I change the 'source' to HDMI for my IPTV box.
Finally, I have a 3 speaker sound bar. From what I've read, you're facing an uphill battle trying to achieve crystal clear sound if you're using 5.1 surround sound or 3D spatial sounds like Dolby Atmos 5.1.2.

A sound bar should have a HDMI port that is ARC compatible, on modern tv's the Number 1 HDMI port is usually ARC compatible.
Audio Return Channel
The Audio Return Channel (ARC) connects your TV and audio system with a single High Speed HDMI® cable and eliminates the need for an additional composite audio or optical cable.

MY soundbar has RCA and bluetooth.
"The main wired and wireless outputs that you'll find on your soundbar, depending on the model, are:
RCA - left and right, usually red and white
Optical, aka TOSLINK
HDMI

From what I have read from our TV manual, the HDMI ARC connection has only two channels i.e. stereo, but the optical output has the 5.1 channels.

HDMI ARC is a better option. It supports Dolby Digital Plus, Dolby Atmos, and up to 7.1 channels of uncompressed audio while Digital Optical only supports Dolby Digital and up to 5.1 channels of uncompressed audio. HDMI ARC also offers features like CEC in which your TV remote can control the volume levels of a connected soundbar or A/V receiver.

Hi all, Most televisions these days have a optical tosh output, unsure if it is just stereo or 5:1 sound, but you could take the optical output and feed that in to a optical to analog converter ( this is what i have done with my own set up as the amplifier ( 2 channel only ) and the rest of my audio equipment is on the other side of the lounge room ) and feed that into your hearing loop amplifier/transmitter.
That way you can have the sound level of your hearing loop set to your preferences and the rest of the family can adjust the television sound to there own requirements. Also have a look at Sennheiser hearing aid head sets. Not cheap but from what i have heard do work ??

My understanding is dicussion are on going as seems all modern tv's fail to allow for the hard of hearing with sound, all allow the text for totally deaf. Personally I don't enjoy reading the screen text to watch a movie. Haven't watched a movie for 30 years for that reason, untill I upgraded hearing aids
If you spend enough money on a hearing aid and connect via optical cable it works well except you have to buy a splitter for optical so others can hear though. Not all spliters will work on some tv's.
It is such a mine field but am thankfull I have sight and 20% hearing, much better than some.

I find that the "hard of hearing" are discriminated against all the time. Went on a small water taxi trip to an island, so they play over the speakers the safety instructions, with bloody back ground music DUH! couldn't make out a word.
But as woolman has, and what brought on this discussion, is that I have a similar setup, connecting the little black box to the optical fiber via a splitter. But the thing is that even changing the settings on the TV and the sound bar, to speech mode, the sound clarity for speech is nowhere near as good (but it improved) as it is transmitted via blue-tooth to the hearing aids. I'm thinking the black box is accessing the dialogue sound channel.
What pisses me off, is the audiologists, after having done 5 years at Uni, know SFA about this, and seem only intent on selling hearing aids.
I am now living in a lifestyle village, and those people living in the near area, all have the same issues. I am due for new aids in three months time, and I bet the phone will be ringing red hot from the hearing people, I will have great difficulty sitting there and keeping my temper in check.
my mission in the coming days is to see all the neighbors and look at adjusting TV and sound bars to get better speech clarity.
