    The objective of the present study was to investigate human perception and SBS symptoms when people are exposed simultaneously to different levels of air pollution and ventilation noise. The air quality in an office was modified by placing or removing a carpet and the background noise level was modified by playing a recording of ventilation noise. Thirty female subjects, six at a time, occupied the office for 4.4 hours. The subjects assessed the air quality, the noise, and the indoor environment upon entering the office and on six occasions during occupation. Furthermore, SBS symptoms of the occupants were recorded throughout the exposure period. During occupation, the subjects performed simulated office work. The results show that elevated air pollution and noise in an office can interact and negatively affect office workers by increasing the prevalence of SBS symptoms. A moderate increase of ventilation noise (with a neutral frequency spectrum) from 42 dB(A) to 45 dB(A) had a strong impact on the percentage of persons dissatisfied due to noise.
