Lower the Sound
Hit the mute button -- or at least lower the sound.
"Noise-induced hearing loss is completely preventable," Peterson says. "If something's too loud, turn it down, walk away from it, or block it out." Apply these strategies to a blaring television, a jackhammer on the path of your usual stroll, or an earsplitting concert. "Earmuffs marketed for NASCAR fans work well," she says. These come in both adult and baby sizes.
Do a sound check on toys: hold them against your ear, then about a foot away. If it's too loud for you, it's too loud for your child. Teach children to keep noisy toys away from their ears, and turn off the sound frequently to let ears recuperate.
