Subjects were classified into several groups based on their scores on extraversion, neuroticism, psychoticism, and lie scales of the Eysenck Personality Questionnaire. They were instructed to estimate the magnitude of annoyance of 27 aircraft noise stimuli while engaged in viewing television. Test/retest correlations between average annoyance estimations (over the 27 noises),slopes and intercepts of annoyancefunction in three test sessions (three different conditions of test room illumination), as well as split‐half reliabilities, showed that annoyance measures were stable and consistent among the subjects. The slope increased and the intercept decreased when the illumination was lower than ordinary in psychotics (but not in nonpsychotics) and in low‐Lscorers (but not in high‐Lscorers). The intercept tended to correlate positively while the slope correlated negatively with introversion, when illumination was brighter, and the slope correlated negatively with neuroticism whet illuminations was dimmer. The average estimation measures showed that hysterics (neurotic extroverts) are high annoyance estimators, where dysthymics (neurotic introverts) are low annoyance estimators of noise at relatively high levels (ranging from 84 to 92 dBA, peak value).
