Abstract
This investigation examined the effects of low, average, and high noise levels on the task performance of fifth level students with average aptitude and mathematical ability. Overall effects, as well as effects on work groups were analyzed. A total of 72 students participated with 18 working in isolation and 54 working in small groups of three in an experimental setting. Noise taped in a class area was used and volume adjusted to designated decibel level before each task performance. The average decibel level (40 to 50 db) was the same level found in class areas of two open area schools. Low (zero to 10 db) and high (70 to 80 db) noise levels were chosen on the basis of results and recommendations from previous studies. Three worksheet forms using three row, six digit addition problems of the same difficulty were utilized as tasks. Task performance variables of time taken to complete and number of items correct were analyzed. Students' preferences were also felt to be important and students were asked whether they preferred: (a) to work alone or with a friend and (b) to work with low, medium, or high noise "when doing very important homework." All students were exposed to each of the three noise levels for ten minutes with five minute rest periods between task performances. All students worked each of the three worksheet task forms..
