Abstract

A method for direct measurement of organic reactions (brain waves) was used to evaluate interior road noise. This was used in addition to the conventional, indirect method of descriptive sensory evaluation. The results showed that the annoyance factors in perception of sample sounds that included road noise could be divided into an active pleasant-unpleasant factor and a passive comfort-discomfort factor. The use of brain wave measurement for the passive comfort factor demonstrated the possibility of obtaining objective descriptions that are statistically significant.
