Noisy Classrooms Most Challenging to Youngest Students
Noisy classrooms aren't just bad for harried teachers' nerves, they can significantly affect the ability of students to listen and learn. Researchers at the Boys Town National Research Hospital in Omaha, Nebraska, have built a unique simulated classroom to help measure the scope of those effects and how they can be avoided. The model classroom consisting of a desk at which test subjects are seated surrounded by an array of five LCD monitors and loudspeakers was devised by architectural acoustician Daniel Valente and audiology researcher Dawna Lewis of the Boys Town Listening and Learning Lab. In a recent study, the researchers tested young and older elementary students as well as adults in the classroom. Although increasing levels of classroom noise and reverberation reduced the comprehension of all subjects, the youngest students 8-year-olds were the most adversely affected. "The combination of the difficult task as well as increased background noise and reverberation led to the younger children having a har
