“…Although the proposed method improves the spatial perception, the reproduced sound field is not identical to the desired sound field. Sound field is determined by both sound pressure and its gradient, which is proportional to particle velocity 15‐17 . The proposed model is built on an assumption the same as shown in reference 8 .…”

Summary Three‐dimensional (3D) audio reproduction techniques reproduce realistic sound sources and spatial perception for listeners. However, it is a rather difficult work to configure all the parameters in the previous 3D reproduction systems since ordinary users hardly possess professional acoustic knowledge. In this article, we developed a sound source distance reproduction model and design an online parameter computing framework for users to generate reproduction parameters based on a cloud computing platform. The proposed model reproduces sound direction and distance cues under specific conditions. Subjective experiments are executed to assess the spatial reproduction performance in a real environment and objective experiments are performed in simulated scenarios. Both the subjective and objective experiments show that the proposed method improves the spatial perception of sound events. Since the reproduction model depends on environment and loudspeaker array configuration, a cloud parameter generation framework is developed for users to generate acoustic parameters for the reproduction system.

“…Establishment of models: Discrete model was adopted for model establishment. As for GFRP-confined concrete short columns, there was no obvious difference in analysis results if friction is considered or not 8,9 . As the constraint effect of GFRP material on concrete is very strong, we assume GFRP tube, concrete and steel rebar or section steel are bonding fully with each other, the slip phenomena is not considered.…”

Glass fiber reinforced polymer (GFRP)-confined concrete short column is a new kind of composite member composed of outer glass fiber reinforced polymer tube and inner reinforced concrete or inner steel-reinforced concrete, whose two common section forms are as shown in Fig. 1. The GFRP tube can not be subjected to pressure directly, but make concrete strength increased by the combined confinement effect with stirrups in horizontal. In order to avoid the longitudinal stress being transmitted to GFRP tube directly, there is always a proper gap left between the tube and the beam or at the column base, which also solves the connection details of casing concrete structure 1. This composite member has so many merits to make itself widely used in the bridge construction and ocean engineering, such as good ductility of steel, lightweight, high strength and strong corrosion resistance of GFRP tube and high compressive strength of concrete, etc. 2-5. Previous reports 6,7 , focus on the bearing capacities of GFRP tubed short columns filled with reinforced concrete (GFRP-RC) and GFRP tubed short columns filled with steel-reinforced concrete (GFRP-SRC) and have presented calculating formulas, but intermediate principal stress is not considered in the data regression method, simple superposition method and unified theory method they have adopted. In document 8 , it is not exact that steel rebar content

“…Unfortunately, there were infinite solutions since the fourth and fifth loudspeaker weight values were free variables and there were no experimental results to confirm the performance. Another amplitude technique developed by Zhang [8] kept particle velocity while sound pressure was not maintained.…”

Sound pressure and particle velocity are used to reproduce sound signals in multichannel systems. The two sound properties were estimated step by step and particle velocity was scaled due to ill-conditioned equations in Ando's study. We explore a new system of equations to maintain both sound pressure and particle velocity. The weight equations are solved in a non-traditional way to figure out exact solutions. Based on the proposed method, the perception of the direction of a sound event and the distance to the listening point are both reproduced correctly in a three-dimension reproduction system. The comparison between the proposed method and Ando's method is outlined and the proposed method is more flexible and useful. Objective evaluation shows the wavefront in the proposed method is more accurate than Ando's method and subjective evaluation confirms that the proposed method improves the spatial perception of sound events.
