| Hello everybody,
I am viewing a trace file with Movie mode to see how SPL varies according to the rays away from the source.
To simplify the trace file the cutt off criteria are: 200 rays/speaker, order 1, loss at 60 dB, 300ms cut off time and directed emission. Speaker level is 86.4 dB @ 1KHz.
The problem is that once the rays hit the ground (concrete floor) most of them dissipate, except 8 or 9 that reflect the color corresponding to a very high level (in the range of 130 dB).
It is very rare because I've been looking individually rays, one by one (Ray Info Table), and none of them has this high level. But there are 8 or 9 rays whose level in > level out (negative loss in, for example, level out 86.4 dB and level in 87.11 dB @ 1KHz).
How is this possible? Help please! |

| Dear user,
Could you please send me the (packed) Project for further analysis? It would be interesting if you could send also the saved trace file.
Please send to pedro.lima(at)afmg.eu
Thanks, |
