Description: 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.
