This study focuses on the influence of specific sound frequencies on pilot psychophysiological condition within a simulated cockpit environment. Conducted using a flight simulator, the study involved fifteen male pilots with an average of 175 flight hours. The experiment consisted of three key phases: a hearing test, a familiarization flight, and the experimental flight where specific sounds within the 498 Hz to 4000 Hz range were played at 64 dB. These sounds, typical of cockpit noise, were integrated into flight scenario to assess their physiological impact on pilots, monitored via electrocardiograms and focused on heart rate variability, respectively. Also, subjective data were collected using questionnaire. The results suggest, that the specific noise can negatively affect pilots' psychophysiological conditions, increase perceived workload and decrease comfort.
