Noisy TV's: Is There a Reason for the High Pitch Sound?

[Stevedye56]

Im curious about this question because of the TV's at school. I can hear a TV on in a house with extrenious noise even if the TV is muted. I asked my science teacher if she could hear the TV when it was on and she said she heard the sound but that's all. I hear a very high pitch noise when a TV is on is there any reason for this? Does anyone else experience this? The noise is also extremely anoying and gives me a headache, probably the reason why i don't watch tv...

I wouldn't worry about it. The same subject has come up in two other threads I can think of in the past 3 years.

Don't worry about it. When you waste too much bandwidth an alarm will go off: you'll hear an extremely high pitched noise that will give you a headache.

Ah, that's what it is. Flyback transformers!

They obvioulsy have to do with why the crazy colory changing channels you don't have are a lot louder than the channels you do.

Hmm? You don't think it was a perfectly cromulent use of the word?From the OED:
"characterized by spuriousness"

Oh, I feel good!
BTW:
From Wikepedia "Simpsons Neologisms"
http://en.wikipedia.org/wiki/Cromulent

Cromulent
A word meaning valid or acceptable, coined by David X. Cohen for the Simpsons episode "Lisa the Iconoclast".
When schoolteacher Edna Krabappel hears the Springfield town motto, "A noble spirit embiggens the smallest man," she comments she'd never heard of the word embiggens before moving to Springfield. Miss Hoover, another teacher, replies, "I don't know why; it's a perfectly cromulent word".
Later in the same episode, while talking about Homer's audition for the role of town crier, Principal Skinner states "He's embiggened that role with his cromulent performance."
Based on the context in which Miss Hoover uses the word cromulent, we can interpret that she intends it to mean "legitimate", "applicable" or "appropriate." Principal Skinner seems to use it to mean "more than acceptable" or "more than adequate"; these usages would also (in an assumed lexical context) satisfy Miss Hoover's use of the word. Perhaps both characters intend it to mean "authentic", which would validate both uses of the word (e.g. "it's a perfectly authentic word" and "he embiggened that role with his authentic performance"). Lisa uses it later in that episode, when instead of telling the truth about Jebediah Springfield, she accepts that the myth and the made-up words have inspirational value. The word has a sort of recursive irony about it: as a made-up word it possesses none of the qualities that it describes.
Both "embiggen" and "cromulent" were quickly adopted and used by Simpsons fans. Cromulent has taken on an ironic meaning, to say that something is not at all legitimate and in fact spurious. Indeed the DVD commentary for "Lisa the Iconoclast" makes a point of reinforcing that "embiggen" and "cromulent" are completely made up by the writers and have since taken on a life of their own via the Internet and other media.

Webster? Respectable? The man was an utter abomination!

A compromise. Since we can't settle on a dictionary, we'll just google the word 'cromulent' ...

... and voila! Cromulent is the bittersweet life and times of a quirky young college girl.

From Jan 13th, 2006:

Yesterday, I received the best gift.

It was given to me by a coworker. I was deeply absorbed in thought, meditating blue highlighter on yellow legal paper, when she peered into my cubicle.

“I have a late Christmas gift for you,” she said, looking in.
“I didn’t have any wrapping paper, but here you go.” It was wrapped in a FedEx delivery envelope.

As she walked away, I delicately tore away the tape. Inside
was a dark wooden box with a symbol etched on top. It looked like a calligraphy of nothingness. I opened the box to see if there was a definition inside. It was empty.

I asked my cubicle neighbor what the symbol meant.

“I think it’s ‘Om’.”

“Well, what’s ‘Om’?”

“I don’t know, but people say it a lot at the beginning and
end of prayers and stuff.”

“But what does it mean? Is it like hello? Is my box saying
hello?”

He shrugged. “I don’t know.”

So we googled it.

It symbolizes ultimate Reality.

Another coworker came by as we were ‘Om’-ing.

“Oh ‘Om’?” He said. “Did you know that if you pronounce it
perfectly, it forms all the possible sounds you can make with your
tongue and mouth? It starts from the back of your throat like, like” - he pronounced it perfectly.

So a coworker gave me the gift of ultimate Reality and inside it was nothing.
