An immersive subjective evaluation method for the sound quality in civil aircraft cabins

The sound quality and comfort inside civil aircraft cabins have gradually become a key factor affecting their market competitiveness. Optimizing the cabin noise environment and improving comfort are of great significance. This article is based on a simulated three-dimensional sound field environment inside an aircraft engineering prototype, selecting eight seats and using the grade scoring method to conduct subjective evaluation tests on the sound quality of a certain type of test aircraft under six operating conditions, including ground taxiing, takeoff, cruising, and so on. After excluding irrelevant results, accurate subjective evaluation results for each seat and working condition are obtained.
