Effects of steady‐state noise and temperature conditions on environmental perception and acceptability

摘要: The combined effects of noise and temperature on environmental perception acceptability were studied 18 lightly clothed subjects (0.6 clo), individually exposed for 2 h in a climatic chamber. Three homogeneous conditions chosen (air at 18, 24 or 30 degrees C, air velocity =0.1 m/s). For each them, three different levels continuously maintained (35, 60, 75 dBA, recorded fan noise). divided into groups group experienced only one single thermal condition, level noise, during experimental sessions. Subjective answers about comfort obtained t = 120 min. Main results indicate that acoustic decreases when environment is far from thermoneutrality. Although the did not influence physiological data, our show whatever ambient temperature, unpleasantness higher increases. Finally, equivalence between sensations proposed short-term exposure (1 degree C 2.6 dBA) steady state 2.9 dBA). In conclusion, this study strongly suggests interactions components do exist, right perceptual level, might explain some cognitive performance.
