Imagine reading a book where every fourth word is blacked out or missing completely. Imagine reading this article without every fourth word. Wouldn’t make much sense would it? [Editor's note: This article was written by CRI's President Werner Braun. For more information, visit the CRI Blog.]
It has been documented that excessive noise and reverberation interfere with speech intelligibility, resulting in reduced understanding and therefore reduced learning. Under these conditions, tests have shown that listeners with normal hearing can understand only 75 percent of the words read from a list. We’re not talking about children with hearing problems here; we’re talking about children with normal hearing.
We have long touted the acoustical benefits of carpet here at CRI. Carpet's ability to absorb noise is well documented as one of its most pleasing benefits whether in a classroom setting or the home or workplace.
How many times have you seen where a teacher had to turn off the air conditioning in a room just to speak to the classroom? In a survey by the General Accounting Office, school administrators ranked poor acoustics as the most significant problem affecting the learning environment. Twenty-eight percent of responding schools, representing 11 million children, identified acoustics as being unsatisfactory or very unsatisfactory.
Researchers at a conference of the Acoustical Society of America presented evidence that excessive noise levels impair a young child’s speech perception, reading and spelling ability, behavior, attention and overall academic performance. Another study done by two University of Florida colleagues found that students beyond the first and second row in a typical classroom hear only 50 percent of what their teacher says.
It’s pretty simple really: if kids can’t hear well, they won’t pay attention, and they won’t learn. Figure in the fact that classroom sizes are growing and more and more kids are being taught in a second language, and you understand the scope of the problem better.
Carpet is one of the best noise-absorbing acoustical materials. Carpet absorbs 10 times more airborne noise than any other flooring materials and as much as most other types of standard acoustical materials. Carpet also will reduce noise resulting from students sliding chairs or desks on the floor. It can also keep the sounds of footsteps in a hallway from disrupting classes in session.
Carpet is not a solve-all remedy for the acoustical problems surrounding our nation’s schools, a problem that has been overlooked and misunderstood for some time. It is, however, one of the easiest things a facility manager can do to improve the learning environment.
