From one of my recent Google Alerts:
Protecting kids' hearing starts when they're babies , by Angele Sionna:
"...For children even a mild hearing loss can lead to significant developmental problems related to speech and language development, social development and academic success," says [audiologist Pamela] Mason. "Classrooms are poor acoustic environments and are often noisy with activities, this environment is difficult to learn in especially if you have a mild hearing loss."
So how do you avoid hearing loss in children? By starting when kids are babies and toddlers, teaching to keep music, TV and other things should be kept at a decent level.
A note at the end of the article mentions that musician Justin Roberts will give the first "Listen To Your Buds" concert on November 19 at the Museum of Science and Industry in Chicago, Illinois.
