Game Show Sound Effects Borrowed from Other Shows

I don't think Wheel has ever shared a buzzer effect with either Pyramid or Price. The Pyramid buzzer is quieter and the Price buzzer has a more nasally sound to it.

Things I'm aware of:

• The wrong-letter buzzer from pre-Season 7 Wheel was used as a time's-up buzzer on the 1978 version of High Rollers.
  
• The TPIR losing horns have shown up on other G-T shows (e.g. Card Sharks).
• The sound effect that is used to reveal a Fast Money response on Family Feud was on Trivia Trap first.
• Late '80s-early '90s Nickelodeon tended to use the same two buzzers across their shows.

Which Price buzzer are you referring to? The one you'd hear, say, if you were over on your showcase or pulled a strike in 3 Strikes (etc. etc.), or the harsher one you'd hear, for example, if you rolled a wrong number in Dice Game or didn't have all five numbers right in Cover Up (among other uses)?

Well, the regular TPIR buzzer may have the same E-flat tone as Wheel's Bonus Round Buzzer, but I can tell they're different. I don't think I can explain it in words, but I'd be surprised if they're the same only double-clipped for Wheel. Wheel's sounds much sharper. If someone had a sound manipulator and stretched the buzzer sound, I think the sharpness should show.

BTW, speaking of Wheel's Bonus Round buzzer, that was used as the buzzer on On The Cover, hosted by Russian Roulette's Mark L. Wahlberg.

The buzzers are slightly different.

Test 1(Buzz test): WOF buzzer first. Price buzzer second: vocaroo.com/i/s0Eqpys4bME8
Test 2(Tone test): Price Buzzer first. Wof buzzer second: vocaroo.com/i/s1JwEbBpkxJM

How is that possible?  Feud started in the mid 70s while Trivia Trap was an 80s creation.  Unless I'm just confused on what you're talking about.

I found one that goes back a ways: the higher-pitched 1981-1989 Bonus Round countdown beeps were first used in 1975 on "Knockout" and "Give and Take."

Another obscure one: the Family Feud ring-in sound was the "time's up" buzzer on Chuck Henry's Now You See It.

And one from across the pond: on Family Fortunes, the laser sound effect heard when the top answer was revealed was also the sound signaling a school prize on the original UK Blockbusters.

Someone mentioned On The Cover earlier. From that show, the sound effect used in the Bonus Round when the lights were being dimmed is the same sound effect used on Deal Or No Deal when a case was being opened.

Now, the original "wrong guess" buzzer on Wheel was used as a "time's up" SFX on Bullseye.

The buzzer heard on many NBC shows (Sale, Password Plus, Card Sharks) can still be heard today on Watch What Happens Live when they play games. No not the NBC Claxon...the other one.

However, the dreaded NBC Claxon appeared on the first few weeks of Password Plus and Card Sharks (it remained on the latter for a Money Cards-ending bust); MG/HS when the Super Match was lost; Scrabble when the Sprint was lost... 

NBC similarly had bells that crossed over several shows.  Can't think of the names given to them, but...
Card Sharks (Perry) correct guess/entering an answer bell = correct answer/Super Match entry on MG/HS; match on Classic Concentration; used on Scrabble.
Correct guess on Sale of the Century = part of advancing in round one of Hitman (combined with bell mentioned above, and Super Password password reveal sound), briefly used for a correct answer on Hot Potato. 
Password Plus password reveal/correct answer = Blockbusters '80 when white captures a block.
Super Password correct answer bell = also heard on several NBC shows, Blockbusters when red makes a capture; original correct answer on Classic Concentration; etc. etc.  Crossed over to Match Game '90 on ABC. 

Illegal clue on PW+ = Of course, crossed over to Super Password; also heard if you give an illegal clue in Turnabout on Child's Play. 

Blockbusters, both NBC Passwords, and others had the same countdown effect. 

Dawson/Combs chimes for the number one answer or finishing Fast Money = correct guess in One on One on TTTT90. 

Of course, the famous CBS/Price "bell" could be heard on most shows coming from Television City. 

And I still say that the Family Feud "clang" is at least similar to a clang heard from the Everlasting Gobstopper machine in Willy Wonka and the Chocolate Factory.
