Two aircraft simulation tests were performed under laboratory conditions: A 3 (sound pressure levels) x 3 (frequencies) experimental design was applied to both studies. Each frequency was operationalized by the presentation of current noise samples recorded at different seat locations in a real single-aisle aircraft (front, middle, rear). For front and middle noises, levels of 66, 70, and 74 dB(A) were applied, for noises in the rear section levels of 70, 74, and 78 dB(A) were played-back. Comfort sensation was measured by a semantic differential consisting of 24 bipolar adjective pairs for the evaluation of aircraft cabin noise with respect to sound quality and annoyance. Communication interference was examined by measuring the speech intelligibility of loudspeaker announcements presented at a constant level of 70 dB(A). Additionally, subjective evaluations of the communication situation regarding concentration, coping, annoyance, subjective speech intelligibility, and speech quality were used. Noise-induced performance effects were tested in the first study by means of a three-minute version of the psychomotor vigilance task (PVT), a simple, high-signal-load reaction time test. Since the results of the PVT were not significant, a three-minute computer version of the d2 test of attention was designed for the second study.
