An experiment was performed in a lecture hall on students, to assess the effect of ventilation noise on concentration and fatigue. The students were tested with the ventilation fans both on and off. As a group the students reported more fatigue during lectures when the fans were operating. States that this environmental effect explains about 39% of the variance in fatigue ratings and may be sufficient to affect adversely the attention of students within these settings.
Background sound pressure fluctuations (5 dB) from overhead ventilation systems increase subjective fatigue of university students during three-hour lectures.
