LINFLOW can be utilized for the computation of sound pressure levels at rather complicated geometries. For this particular simulation, the structure (i.e. the head) has been assumed infinitely rigid. Concerning the simulation, we would like to mention that

• Compared with the simulation of the airflow over a car body, the solution time in LINFLOW is rather extensive (more than three times as long but still less than 70 seconds). The reason is that we compute a complex solution, and that the far field results are determined.
• It has been assumed that the air is at rest. In LINFLOW, it is easy to account for the air moving (e.g. to determine the acoustic pressure as a function of wind speed).
• It would not have been any problem to run the simulation as a Vibro-Elastic simulation, accounting for the elasticity of the ear-drum and the elasticities of the ear-channel (given that the elastic properties are known).
• Again, we see how easy it is to run LINFLOW in the easily configurable ANSYS/Classic menue system.

There are other applications of LINFLOW acoustics as well. One application would be the determination of the acoustics in a concert hall. LINFLOW covers the complete frequecy range from zero Hertz to gigahertz accurately.
