The impact of environmental conditions like noise and vibration at the workplace of cabin and flight crew on well-being, performance, and health was identified by measurements in long-haul flights and tests in simulators facilities. Various indices were developed to characterize the human response. The complex data evaluation reveals a significant influence of vibroacoustic and climatic variables on several indices representing the physiological and psychological state of crew members, but the separation of variables is difficult. Some mutual interaction like duration of impact is identified; other dependencies are not yet clear. Prognosis of human response is possible with an artificial neural network. A relationship between independent variables (characterizing the environment) and dependant variables (indicators of the human response) is well described by the ANN. Direct input-output dependencies of selected parameters reveal a complicated mutual interaction of numerous variables. The noise level exerts significant influence on various symptoms and health indices, in particular when the level increases with time of work. Environmental impact becomes aware with duration of flight.
