It’s been proven in many studies that background noise can affect children’s ability to learn. Until a child is in their teens, it’s hard for them to separate sounds they want to listen to from those those they don’t want to focus on. It’s the most difficult for kids under the age of 5 and it can negatively affect language development and sleep.
If you’ve ever been at a loud restaurant or party and had to work hard to understand the person talking to you, that’s basically what it feels like. It might even be a classroom or a daycare or at home where they are struggling to understand!
If you’ve ever been at a loud concert with a PA and you can’t understand what the person with the mic is saying – that’s another example of how kids struggle with intelligibility. If an environment has loud background noise and the speaker isn’t crisp and clear (muffled, reverberant, etc) it can harder for them to understand, too. Can you imagine how much harder it is to learn in a classroom where you can’t hear or understand the teacher all the time?
Researchers have looked at noisy schools and found:
Preschoolers in daycares near elevated trains in New York City performed worse on gross/fine motor skills than children in quieter neighborhoods
Older students who attended school near New York City airports had lower reading skills than schools further from the airport
Children in Los Angeles who live near noisy highways had lower reading scores.
A school in New York found students in classrooms adjacent to a train track had poorer reading skills than students (of the same age) in classrooms away from the train tracks. When the train tracks and the classrooms were acoustically treated (to be less noisy), the reading skills of the two classrooms showed no difference.
What parents can do:
Keep the background noise down at home. Try turning off the tv or music if it’s not the center focus.
Talk to your kids about noise and how it can affect their learning. It’s ok to speak up if it’s too noisy or they can’t understand well.
While you’re at it, talk about the risk of hearing damage and why it’s important to protect their ears.
