scipaClassroom acoustics and football interference
June 16th 2006 12:15
The Acoustical Society of America (ASA) has proposed a new learning aid for schools – acoustical guidelines for the design of classrooms.
"ASA has been concerned for many years about poor acoustics in America's classrooms and the deleterious effects poor acoustics have on the ability of children to learn and teachers to teach," Eurekalert quotes ASA President William Yost, PhD, in announcing the policy statement. "The best way to improve classroom acoustics is through the proper design and renovation of classrooms as specified in ANSI S12.60. Using sound amplification in an attempt to overcome poor classroom acoustics only makes the situation worse. There should be less sound in the classroom, not more."
Acoustics may also be put to use in football stadiums, to defuse abusive chants hence preventing soccer riots. The system involves the installation of microphones around the stadium which return the sound with a split second delay. The delay will scramble the chants, making it difficult for them to propagate. Meanwhile, players will still be able to hear the supportive roar of a crowd.
