The increasing air traffic in the past has led to the fact that and more and more people were affected by aircraft noise. Since the potential of reducing noise level of current aircraft will be limited in the future after recent developed techniques have been realized in practice. Therefore, additional efforts are necessary to improve the sound quality of aircraft noise and give hints to aircraft manufactures concerning components that have to be acoustically optimized. The present study describes the development of an item list for a semantic differential (SD) that is appropriate for the determination of different perceptive features of aircraft sound quality and focuses on the estimation of the reliability of this new instrument. The selected 10 SD items have relation to the sound components emitted by the different technical devices of airplane engines. The analyses of the measurement characteristics of the different items were based on G-theory. This method presupposes data possessing interval-scale-level characteristics. Therefore, the used rating scales were examined with respect to this attribute. The results verified that the data fulfill this precondition. The results gave evidence that the judgments show large inter-individual differences. The proportion of variance which can be traced back to the factor 'aircraft sound' amounted to at most one-fifth of total variance indicating that the differences between the aircraft sounds are rather small. Nevertheless, the findings demonstrate that it is possible to measure not all but several decisive aspects with sufficient reliability and expense.
