Lincoln uses sound-canceling earbuds to try and drown out his sisters.
Lincoln comes back home with a new comic book, and plans to read it in complete peace and quiet, but in a family like his, he can barely find any of it. While in the living room, he sees a TV commercial for "Noise-B-Gone 2000", a pair of earplugs that can block out all loud noises with soothing sounds, and he orders them without his sisters' knowledge. After getting them in the mail (same-day delivery via drone), he puts the plugs on and finds that he can no longer hear his sisters' noises. As he goes through his day in peace, his sisters ask him for various favors, and Lincoln, unable to hear them, unwittingly agrees to them, just to shut them up.
The next morning, Lola wakes up Lincoln to remind him of the promise he made to her the previous day, telling him to do it by 3:00. However, she's not the only one he unknowingly made a promise to. He also promised Lynn to be her sparring partner for kickboxing, Leni to act as a mannequin for her new fashion idea, and Lori to use him as an ottoman to rest her feet, so she can paint her toenails. As Lincoln is roped into the other promises he unintentionally made to his sisters the previous day, he asks them what was the promise he made to Lola. They all react with fear and horror, and they tell him stories of the extreme acts of revenge Lola extracted on them for making her mad (such as popping Lynn's soccer ball for eating the last pudding, giving away Leni's stuff for breaking her tiara, boiling Lori's phone for not saying "Bless you" when she sneezed, and doing away with Lana's pet frog Seymour, for distracting her while putting on her makeup), making Lincoln ever more afraid of what Lola will do to him at 3:00. Lincoln decides that he should do all the things Lola would expect him to do for her, such as cleaning her room, cleaning out the gutters, and creating topiary statues in the front yard.
When the clock strikes 3:00, Lola bursts in saying that Lincoln has failed her, and she ominously approaches him, as she prepares to unleash her vengeance. Cowering before her, Lincoln confesses that he was wearing earplugs and couldn't hear her demands. Lola suddenly calms, and she reveals that she knew he was wearing the plugs on the whole time. It's also revealed that she had the others tell Lincoln made-up stories about her to teach him a lesson; they remind him that he can't ignore his family and that they have to live in a noisy house altogether. However (and unfortunately), Lola has inadvertently forgotten to fill Lisa in on the plan, as her experiment about to explode and the others (except Lisa) are in shock to expect what is coming to them. Lisa's experiment creates an explosion so powerful, that it blows the whole roof off of the house, and lands back upside down. Alongside that, it deafens all of the Loud kids (except for Lisa), as Lincoln yells out, "NOW I CAN'T HEAR ANYTHING!", due to going deaf for real.

The title of this episode is an oxymoron since silence doesn't make a noise.
There are some subtle hints that indicate that Lisa wasn't in on Lola's plan:
When Lola gathered her sisters after finding Lincoln's earbuds, Lisa was not with them.
When Lola revealed her plan to Lincoln, Lisa was the only one not present.
The background music playing on the title card plays some audio of the sisters causing a ruckus around the house.
Lola's trophy case has 13 shelves and 44 trophies.
The girls say they all live in a noisy house, despite the fact that they never complain about the noise.
Lola forgetting Lisa in her plan is what ultimately causes Lola (as well as the other sisters) her comeuppance.
Scenes of Lynn attacking Lincoln during the kickboxing scene have been removed in the UK version. Specifically, Lynn's dropkick and Lincoln's subsequent reaction, Lynn repeatedly kicking him, and her second and third hits were removed.
Futurama - Lincoln's line "Take my money!" references the Futurama character Philip J. Fry, who uses the famous phrase "Shut up and take my money!", in the episode "Attack of the Killer App" (the phrase also became an internet meme).
The Godfather - The flashback were Lynn screams in terror upon finding her deflated soccer ball that Lola placed on her bed references the famous horse head scene from this 1972 film. Ironically, Lynn, Lucy, and Zach's voice actress Jessica DiCicco appeared in The Godfather Part III as a little girl.
In the Latin American Spanish dub, for about one second, Lincoln's voice sounds different (one-half line isn't dubbed by his LatAm Spanish voice actor), when he says "Todo porque accidentalmente rompiste su tiara?" ("All because you accidentally broke her tiara?").
The Manotard Leni has Lincoln model has legwarmers, which is strange since in "The Sweet Spot" she claims she hates legwarmers.
In the end credits, Daran Norris' name is misspelled as Daran Morris.
When Lana warns Lincoln about the "Frog Fiasco", she suddenly has full front teeth and no missing teeth.
The TV announcer says that the Noise-B-Gone 2000 earbuds cost $19.95, but the TV says that they cost $19.99.
