my problem in the simulation with a suspended surface

[yanndesa]

Hi,

I have the following problem... I am drawing a geometry in the sketch up and I insert acoustic baffles in its interior, in a suspended way. However, in SPPS it does not recognize the absorption of these surfaces. Can someone help me please?

Hi,
Do you have any detail to share on your issue ?

Hi Nicolas, thank you for your reply.

This image is my geomtry in sketch up. I exported it in 3ds format and imported it in isimpa normally. I configured everything according to the tutorials, but I can't make the absorption on suspended surfaces be recognized. The results generated are as if they did not exist.

Do you have any suggestions on how the software can correctly recognize these surfaces?

In the SPPS configuration you can set 10K particles in order to display the trajectories of particles, you can see if they bounce or not on the panels.

Ok, thank you

I did that now and there are not so many particles that collide with the panels, I'm trying to put higher sources and greater number of particles per source to see the result

[yanndesa]

do you think this geometry is too complex? using as correction options to find the best results

It is an interesting room. It seems a very large space, so you will need to consider a large amount of particle. Check the Schroeder curves for a given receiver, and observe the sound decay to see the dynamic. It a good way to know if you will be able to gave relevant results.

Hi Picaut,

Yes, it is a large room, your volume is more than 3000 m³. Thank you for your reply. I will be try simulate with 50 millions of particles and see the results.
