I have been wanted an HDTV for some time to finish my already killer system, however, 22 days ago (whose counting) I came down with an uncurable disease of my inner ear, so the noise that is emitted from a CRT television is the death of me.


Will any RPTV not emit that sound or do I need to get an LCD plasma tv?


I can get a floor model Panasonic 47" the one without the built in screen protector for 1100 bucks. Seems like a great deal. But my brother will have to get it for me.


I need to know if this tv will not emit the same sound as a CRT tv, if not that will be great.


PS. if it does, how about the Pioneer 533 or Elite, or Toshiba 42 HX 81?


Thanks so much, and I need to act in the next hour. It is 9:51 Eastern Time right now.

UPDATE: Panasonic sold, so now just looking for any tv that emits no noise whatsoever.

I am able to hear a high pitched sound from a CRT TV or a monitor but I dont hear that sound from my Sony 51hw40 RPTV. In fact, when it isnt receiving a signal and its still on, I have no idea it is on. With a tube set, I know right away because I can hear a high pitched "buzz" coming from it.

There may be hope for your situation in the form of...HDTV!


The horizontal sweep frequency of 480i is 15,735 Hz. That's the frequency you're hearing.


The horizontal sweep frequency of 1080i is 33,750 Hz and for 720p it's 45,000 Hz, both of which lie outside the range of human hearing. So, if you get a set that upconverts everything to 720p or 1080i I don't think you'll be bothered by squealing CRTs.


Why not go to a store that's displaying HDTVs and listen for annoying sounds?

David thanks for the explaination.


So would the JVC I'ART that upconverts everything to 1080i be good. For example for NTCS upconverted?


I tried to go to stores but there are so many CRT's plugged in there is no hope. I can here a 9" CRT tv from about 500 yards away.


Thanks so much and keep any info coming guys.


If it helps match my system at all here are the specs:


5 Infinity Overture 1's

H/K 520

H/K 50

Velodyne CHT -120


Doug


So I am guessing RPTV do not have CRT tubes, is that the sound i'm hearing? I'll try to hit the one high end store out here, but Pittsburgh isn't known for highend stuff.

You are actually hearing the power supply flyback rather than the CRT itself, for what it's worth...all CRTs need one.

Holy Cow! The lengths people will go to, to convince their wives they NEED HDTV!!!:D


Just kidding. Any HDTV should eliminate the noise. I find analog NSTC TVs annoying, also. Any TV, including CRTs, that converts everything to progressive scan or HD levels should be silent to you. My Elite 510 (CRT RPTV) line doubles regular TV to 480p, which has a 31.5KHz scan rate. 1080i goes to 33.75KHz. I can't hear either, but the 15.75KHz of "regular" TVs bugs me, now that I don't listen to it all the time.


Find the HDTV you like, then get it. Enjoy. I recommend the Pioneer standard line (like the 533-HD5). Great value, and they have the fantastic line doubler of my Elite 510 (last year's model).

Consider yourself lucky, its a gift not a desease. Not many people can hear over 12kHz. You are a perfect candidate for audiophilia.

Thanks everyone.


I do consider myself very lucky. I have one of the most severe cases of Tinnitus every documented. To top it off I am only 25 and have never exposed myself to loud sounds.


I will have to go check them out, because my hearing has become hyper-active since the onset. Most people with Tinnitus have a hearing loss. However, my hearing is in the upper 1% of all humans.


Seen 7 specialists nobody has a cure or an idea.


Buy you are right, definately a new way to get some new technology!

Here is a different idea.


Get a pair of etymotic in the ear headphones. They have 22 db

of outside rejection. Then drive them with a small headphone amp

and turn them up to the desired level.

How would that help someone who is sensitive to High Frequencies?


Placing a tissue over the tweeter would attenuate the HF. Even better option would be to DIY'ng a tube amp with HF rolloff is a better option.

Hey dougie, I also have a pretty severe case of Tinnitus. The sounds coming from my DTC 100 drives me nuts. My first DTC 100 wasn't so bad but that one got fried and has now been replaced by this "new" refurbished one. It's the fan that makes the noise. Funny how the fan from the DTC 100 drives me nuts but I have to sleep with a fan on to block the Tinnitus problem I have.


My ear problems however were self inflicted from a loud car stereo that I thought was so cool. Sometimes you learn things the hard way...

I know what your trying to say Adi, but having Tinnitus is not being lucky and it's certainly not a gift. If you had it you'd understand.

From dough's first message, it was not clear to me that the heightened, yet desirable sensitivity to high freqs is caused by a the disease. Frankly, I though he is wrongly attributing the problem to an unrelated disease. Didnt mean to undermine in anyway.
