About This Item


Full Description

This document describes results from an experiment designed to investigate the combined effects of noise and temperature on human comfort and performance. Research has established that poor lighting, noisy work areas, and/or excessively warm or cold temperatures, can and will compromise occupant performance and satisfaction compared to more comfortable condition. In contrast, strong and reliable links between better indoor environment conditions and increased productivity have remained elusive.

The independent variables manipulated in this experiment included five thermal conditions, two sound qualities, and three sound levels. The effects of the independent variables on the opinions and performance of the subjects used in the experiment were measured using self-administered computer-based tools.
