Steve spends the summer after they defeat Vecna teaching El how to make noise
It starts one day in his kitchen, when she catches him whistling. Brows furrowed as she tries to copy him, she asks him how to do it. For a minute, Steve is surprised; what kid doesn't know how to whistle? And then he remembers - El hadn't gotten to have a childhood. Not really. He thinks about all the normal kid stuff she was denied, and his chest aches just a little. He forgets whatever he'd been doing and spends the whole afternoon teaching her how to whistle
Once she has a pretty good grasp on whistling, he asks if she wants to learn how to do it really loud, and teaches her how to whistle with her fingers
Showing her how to snap her fingers is easy, and after she masters that, he shows her how to make a popping noise with her fingers tucked under her chin
He spends one afternoon showing her how to make a hooting noise with her cupped hands, and another how to whistle with two blades of grass. Sometimes he'll find something the other kids in the party don't know how to do, either, and he'll gladly show them, if they'll listen long enough
He draws on every little trick he'd learned growing up, from his friends, from summer camp, from his time in the Scouts. He learns that El has never gotten to play a kazoo, so he makes her one with wax paper and a comb, the way his grandad had shown him so many summers ago, and lets her go to town
By the end of summer, Hopper is ready to murder Steve - except El looks so happy, so pleased with herself, making popping noises with her lips, snapping her fingers, giggling as Jonathan and Will try and fail to copy the bird call Steve showed her. For that smile on her face, Hopper guesses he can put up with it
(He gets his revenge by teaching El how to whistle the Andy Griffith theme song and unleashing her on Steve. It takes a week for Steve to get the tune out of his head)
