Abstract

Background noise levels have been shown to disrupt reading eye movements. This study was designed to investigate sound pressure level changes and the effect each change had upon the number of eye regressions made during a reading task. A OdB sound pressure level was used as a control baseline and comparisons were made to 40dB, 60dB, and 80dB sound pressure levels. The results indicated that sound pressure level changes do cause a significant increase .'in the number of time the eye regressed. The highest significance was noted far the 40dB level and the least significance was noted for the 80dB level. This result may indicate an increase of concentration at the higher sound treasure level which is not present at the lower sound pressure level. These results support the competitive .interaction interpretation of visual and auditory stimulation.
