In order to properly design warning sounds that are affectively suitable to computer users, warning sounds used in Windows operating system were analyzed in terms of their sound properties; frequency band, spectral characteristics and physical intensity. A total of 36 warning sounds (3*4*3) were generated and tested with respect to three experimental variables. Among 178 affective adjectives that are related to hearing and sounds, seven representative affective factors were abstracted by statistical grouping techniques. In the experiment, subjective preference tests were performed for the 36 warning sounds according to the seven affective factors. From the result, the affective factors were again grouped into three major factors and the 60dB boost-type warning sound at the low frequency band were, in general, the most preferred, closely followed by the 70dB cut-type sound at the middle frequency band. The former received most favorable responses in terms of simplicity, clarity, and accurateness, while the latter did in terms of deepness, heaviness and calmness.
