The effects of the absence of noise after repeated exposure on performance time

The present study examined how the absence of noise after its repeated exposure affected the time it took subjects to solve multiplication problems. Sessions one (practices), two and six were carried out under the same conditions for all groups. In sessions three, four and five, however, the intensity of noise differed among groups. Within the experimental groups, the noise level was increased in session three and decreased in session six. A statistical analysis revealed that performance times were not affected by either an increase or decrease in the noise level. As well, no significant results were found between groups in any of the five measured sessions.
