It's when a character (AIRHORN) has a conversation(TRAIN) and you can't hear parts(JACKHAMMER) because of loud noises(TRUCK HORN).
You're watching Alice and Bob talking on TV. Bob asks "How was your day?" Alice replies "Well, it was pretty bad. I woke up when my dog-" A Jackhammer goes off near by causing it to be impossible for the viewer to listen, and Alice keeps talking. The Jack hammer stops-"It was so tiny, I thought it was harmless, but-" Jackhammer again."so I'm like 'Is that all ya got?', and he-"Jackhammer. "AND THEN I TRIPPED AND-"Jackhammer."And that's how my day went". Bob says "Wow. I feel so sorry for you! That WAS a bad day...". What we have here is a perfect example of a Jackhammer conversation. In most cases, all parties except for the viewer can hear what is said. However, on occasion, it's Lampshaded by having characters claim that they're unable to hear them. Could be confused as a posible mix between The Unreveal, Plot-Based Voice Cancellation, and/or Sound Effect Bleep. While these may all seem similar, this trope tends to have less swearing and more gaps between sounds. The "gaps" tend to include sentences or chunks of sentences that seem somewhat unrelated. Usually, it's Played for Laughs, and it isn't quite important to understand what you can't hear because either nobody was supposed to understand it in the first place, or everyone else is supposed to get it but you.
- In the Steven Universe short "Video Chat", this happened to Peridot when her Internet communication breaks up. Ironically, it happens as she's explaining how she got the internet working so well.
- Occurs in"Escaliferb" from Phineas and Ferb:
Malifishmertz:Let me tell you about my plan for seizing control of the Tri-Kingdom Area: You see, I was bullfrog hunting down by the rat-catchers shack and came across...[Malifishmertz rounds a corner while descending a circular staircase; his voice becomes muffled and indistinguishable; comes back into view] ... with the biggest raspberry I've ever seen! It was the size of a cucumber![rounding another corner, becoming again muffled; returns to view] ... is what I said because I had a gag over my mouth.[rounding another corner and muffled once again; comes back into view] And THAT'S why I decided to take over the Tri-Kingdom Area. True story.
- Used in Randy Cunningham: 9th Grade Ninja When Howard tells the Bogger story in "Welcome Back Catfish". What's even more confusing is the is the hand gestures that he uses while telling the story and the fact that Randy is nearly throwing up upon hearing it. It's then used as a Chekhov's Gag to get a monster to throw up one of the sorcerer's orbs of power.
