可视化的声场以上的本地反应阻抗平面。



：你可以进行选择



- 声压相对于距离为1的自由场声压在分贝再1。



- 声压的相位。在学位。



- 过量衰减：总声压，只能用直接的声压分。以dB为单位重1。正值表示衰减（声压比在自由场低级）



- 现场阻抗（相对于空气的特性阻抗）。



- 垂直（表面法）粒子速度。以dB为单位重新1。



- Horizotal（表面平行）粒子速度。以dB为单位重新1。



- 垂直（z）的比率horizotal速度（R）。以dB为单位重新1。



表面阻抗假定了一个exp（一IWT）的时间依赖性，

因此，大多数阻抗将产生积极的虚部。-Sound_Field.m

Visualizes the sound field above a locally reacting impedance plane.



You can choose between:



- Sound pressure relative to the free field sound pressure at distance 1. In dB re 1.



- Phase of the sound pressure. In degree.



- Excess attenuation: Total sound pressure divided by direct sound pressure only. In dB re 1. Positive values mean attenuation (sound pressure　　 is lower than in a free field)



- Field impedance (relative to characteristic impedance of air).



- Vertical (surface normal) particle velocity. In dB re 1.



- Horizotal (surface parallel) particle velocity. In dB re 1.



- Ratio of vertical (z) to horizotal velocity (R). In dB re 1.



The surface impedance assumes an exp(-iwt) time dependency,

therefore most impedances will have a positive imaginary part.
