Thread: Question About Clarity

  1. Default Question About Clarity

    As I previously posted, I'm trialing a pair of BTE Unitron Quantom 12's.

    I'm having trouble understanding speech when watching TV. Tried all sorts of settings, but many words and phrases pass right on by and I have to ask my wife what was said.

    Is this common? Is it something that can be adjusted?

    I have other issues which I mentioned in my previous post several days ago.

    Would appreciate some advice.

    You have a flat hearing loss as I have with substantial low frequency loss. I had to switch to power receivers and power domes to keep some of the low frequencies in and that improved speech clarity while watching TV. Pros on this forum may chime in and help more then I can.

    You have to ask yourself, what you are missing. Is it clarity or volume? Ie; does speech clarity improve with added volume from the tv, or does it just get louder, but offer no improvment in clarity.

    This should help you decide, and know what to ask for when you go see your practitioner.

  4. Default Volume Doesn't Improve Clarity

    Volume doesn't improve clarity.

    I've experimented with increasing TV volume while decreasing HA volume and the reverse. I've done this with all three program modes. (with what's been on TV lately, mode #4, mute, is the best choice ....... joke!!)

    Also used the scroll wheel to adjust tone clarity with little no success in each mode.

    The best performance, and then very little, is putting the HA's in the telephone program mode while watching TV.

    Again, don't know if it's a HA performance problem or just the need of adjustment.

    Unless there's a way to improve the clarity, I doubt I'll keep these past the trial period.

    Suggestions?

    Well, there is one more thing to try before deciding on going another route.

    Set the volume of the tv to your wife's prefered volume intensity while wearing your hearing aids, then adjust the volume of the hearing aids to your prefered intensity. Does this improve the sound quality? If not, adjust your comfort/clarity tone control up all the way. Does that improve the clarity? If not, then your hearing aids are not configured for your loss the way you need them to be. If it does improve, then relay the information of what you did to your hearing aids to make them sound good. The onboard DataLogger will be of use to them as well.

    I hope that helps.

    Another possible suggestion is to find out what your speech discrimination scores were on the hearing test you obtained. If your percentages were less than 50% or 60% then it's highly possible that the distortion you are experiencing has little to do with the hearing aids and more to do with the damaged system the sounds are being sent into.

    Speech testing can tell us a lot as far as that goes. It's not to say that the hearing aids aren't at fault, but it's an important factor to take into account when changes to the hearing aids make little difference in clarity.

    If you can find the results and post them that would help in providing you with a more accurate answer as we will have a more complete picture of your hearing.

    I have found that the quality of the sound of the TV makes a huge difference. I have an 18 year old TV that I watch in my bedroom. No matter what I do with the volume on the aids or on the TV I have a problem with clarity. On the other hand my other TV has it's sound routed through a receiver and then to speakers. I have NO trouble with clarity when I watch/listen in this situation.

    I have a print out of my hearing test, but I'm not sure what to look for that will tell me what the speech discrimination score is.

    There should be an area with the letters WDS or SRT. SRT will usually have a number next to it and this is the softest speech sound you could understand. WDS will typically have a % and then a numerical value next to it. It indicates what percentage of words you got correct at whatever presentation level (the numerical value).

    Often looks like this:
    R L
    SRT 30 40
    WDS 84% 76%
    @70 @80

    or something similar. if the % are low, say 60 or below then, in general, speech will always sound fairly mushy or unclear even with increases in volume due to the underlying damage that has taken place in the cochlea.

    It's also possible that whoever did your test didn't do the speech testing...I've heard of pros (usually HIS's in this area) that omit that part of the test.

    There's a chart on the hearing chart print out with the heading: Binaural/Dichotic

    There's an AC column for R & L, all the below are in that column. There many more columns, but they are empty.

    For the Right:

    SRT 70

    WRS1 85

    Score: 80

    MCL 85
    UCL 110


    For the Left:

    SRT 75

    WRS1 90

    Score 84

    MCL 90
    UCL 105


    Maybe you can explain these numbers. I've never received an adequate explanation in almost 10 years of wearing HA's. I've only heard the audiologist mention % of word discrimination loss. I think they mentioned I have an 85% and 75% loss in this area. Whatever it is, it's probably not good.

    The information is off a chart dated 12/5/11 the specialist at COSTCO printed out for me. It's the only chart that's ever been handed to me. I was looking at Phonak, Resound Futures, Starkey and then these Unitrons. I felt the Unitron provider, which dealt in many brands, was providing me with the least amount of BS, best technical advice and had 18 years of experience in our community.


    ALSO: WHY when you print the hearing chart is the right ear on the left side of the page and the left ear on the right??????????? Perhaps because if the audiologist is looking at the patient the right is on the left and left is on the right??????? Just wondering.
