Experimental research on sound quality evaluation of aircraft cabin

Abstract

This paper proposes a construction method for the sound quality evaluation model of the aircraft cabin. By combining the subjective with the objective method, the relationship between the subjective results and the psychoacoustic parameters is established, and the sound quality evaluation model of the sound field in the passenger cabin is formed. The model takes the characteristic acoustic parameters that are more sensitive to the human ear, such as loudness and sharpness, as input, which can efficiently obtain the subjective result of sound quality and accurately reflect the subjective quality feeling of human ear on the current sound field.
