This paper introduced four common test methods of acoustic contribution of body panels. The methods using PU sensor to array measure vibration velocity of body panels. Then, the vibration velocity of body panel multiplied by the area of panel to get the value of sound source intensity. Use reciprocity method to measure acoustic transfer function. In the experiment, the vector sum of the product of sound-source intensity and acoustic transfer function is used to compose the sound pressure contribution of the panels. The experiment proves that the composite value of acoustic pressure spectrum of drivers right ear coincide with the measured value. Therefore, this method is proved to be valid.

Abstract This paper analyses the performance of Differential Head-Related Transfer Function (DHRTF), an alternative transfer function for headphone-based virtual sound source positioning within a horizontal plane. This experimental one-channel function is used to reduce processing and avoid timbre affection while preserving signal features important for sound localisation. The use of positioning algorithm employing the DHRTF is compared to two other common positioning methods: amplitude panning and HRTF processing. Results of theoretical comparison and quality assessment of the methods by subjective listening tests are presented. The tests focus on distinctive aspects of the positioning methods: spatial impression, timbre affection, and loudness fluctuations. The results show that the DHRTF positioning method is applicable with very promising performance; it avoids perceptible channel coloration that occurs within the HRTF method, and it delivers spatial impression more successfully than the simple amplitude panning method.
