• The simulation below shows the propagation of sound waves above ground. The simulation domain is 15 m x 15 m. The sound wave is generated as a sinusodial signal at frequency=200Hz, and amplitude of the sound pressure is 2 Pa which is equivalent to a sound pressure level (SPL) of 100 dB.   (File size: 1.4Mb)             

• The simulation below shows the propagation of sound waves above ground. The simulation domain is 15 m x 15 m. The sound wave is generated as a sinusodial signal at frequency=900Hz, and amplitude of the sound pressure is 2 Pa which is equivalent to a sound pressure level (SPL) of 100 dB. (File size: 1.4Mb)

• The simulation below shows the propagation of sound waves above ground. The simulation domain is 10 m x 30 m. The sound wave is generated as a sinusodial signal at frequency=300Hz, and amplitude of the sound pressure is 2 Pa which is equivalent to a sound pressure level (SPL) of 100 dB. Several parameters such as the partial absorption by the wall, by ground and by trees included. (File size: 4.2 Mb)         

•  The simulation below shows the propagation of sound of a moving source. The simulation domain is 40 m x 80 m. The sound wave is generated as a sinusodial signal at frequency=100Hz, and amplitude of the sound pressure is 2 Pa which is equivalent to a sound pressure level (SPL) of 100 dB. (File size: 2.5 Mb)
