感官空气污染，热负荷和噪声的相对重要性进行了研究，在两个相同的环境室控制条件下。在一个房间中，受试者暴露于不同水平的热负荷或室内空气质量差。对于在该室中测试的每个条件，受试者暴露于具有中性热条件和良好室内空气质量的相邻室中的许多噪声水平，以确定引起相同程度不适的噪声水平。同一组16名受试者在每个室中暴露1分钟后，对两个室中的条件进行了总共68次比较。在23-29°C的操作温度范围内，发现操作温度的1°C变化对人体舒适度的影响与感知空气质量的2.4分贝变化或噪声水平的3.9分贝变化相同。对于高达10 decipol的感知空气质量水平，感知空气质量的1 decipol变化对人体舒适度的影响与1.2 dB的噪声水平变化相同。建立了交通噪声水平与不满意率之间的关系
The relative importance of sensory air pollution, thermal load and noise was studied under controlled conditions in two identical environmental chambers. In one chamber subjects were exposed to various levels of either thermal load or poor indoor air quality. For each condition tested in this chamber, the subjects were exposed to a number of noise levels in an adjacent chamber with neutral thermal conditions and good indoor air quality in order to determine a noise level causing the same degree of discomfort. A total of 68 comparisons of the conditions in the two chambers were made by the same group of 16 subjects after one-minute exposure in each chamber. In the operative temperature range of 23–29°C, a 1°C change in operative temperature was found to have the same effect on human comfort as a change in perceived air quality of 2.4 decipol or a change in noise level of 3.9 dB. For levels of perceived air quality up to 10 decipol, a 1 -decipol change in perceived air quality had the same effect on human comfort as a change in noise level of 1.2 dB. A relationship between traffic noise level and percentage dissatisfied was established
