Computer Pure-Tone and Operator Stress: Report III.
Dow, Caroline; Covert, Douglas C.
Pure-tone sound at 15,750 Herz generated by flyback transformers in many computer and video display terminal (VDT) monitors has stress-related productivity effects in some operators, especially women. College-age women in a controlled experiment simulating half a normal work day showed responses within the first half hour of exposure to a tone generator-created pure-tone. Overall productivity decreased 4.47% in the first half hour and 8.18% in the second hour. Effects of the tone varied with time in the menstrual cycle, high estrogen levels further decreasing performance. Control and experimental groups (N=100) were analyzed. These findings make a direct link between a specific attribute of VDTs and stress symptoms reported in workplace health studies. Because women hear frequencies one to three kiloHertz higher than men and find sounds "too loud" at half the loudness men tolerate, they are more at risk for these stress symptons.
