Evaluation of Effects of Stress and Relaxation Sounds on Work Efficiency Using Biological Signals

Abstract

This research aims at the analysis of effects on work efficiency during listening to stress or relaxation sounds. The work efficiency in this study is defined as the speed and accuracy of work. In order to measure the work efficiency, we evaluated the effects of listening to stress and relaxation sounds using the Kraepelin test, which is often used in the field such as employment and qualification examination. Generally available music was used for the sound to be heard by the subject, and heart rate information and sweating information were the measured as an index of relaxation and stress during work. As a result of the experiment, the effects of stress and relaxation sound on the human work efficiency were analyzed, and it was confirmed that there was the strong correlation.
