When performing acoustic analysis with the space analysis package, is it possible to find out the number of decibels?

I used the script distributed at the above site for acoustic analysis.
The results are output and seem to work well.

Is it possible to set the volume of the sound source from here (for example, 10 decibels for the sound source) or to place an observation point and know the volume at that point (for example, 5 decibels for the observation point)?

I don’t believe this is entirely true, but have reached out to the team to get some clarification.

So the package is still under support, meaning bugs will be fixed. However it is not under development, meaning no new features are being added. New features are being added to VASA which has similar capabilities to the space analysis package, but is 3d in nature. VASA does not support decibel values at this time as such capabilities would require real world calibration and adding sound absorption values to all voxels which would require materiality to be added. All of which is more than the package is intended for.

Thanks for the reply.
I would like to organize the content,

  • The space analysis package does not have the ability to find decibel values (support for the package exists, but no new features have been added).

  • VASA also does not have the ability to calculate decibel values (as this is beyond the purpose of the package).

Is this correct?

I have two more questions (maybe I should post another one and ask)

  • Is there a package that can measure decibel values?

  • I would like to know about educational materials, websites and others where I can learn SPACE ANALYSIS and VASA.

I look forward to hearing from you.

Not that I know of, and it would be very unlikely to be accurate enough to work in real world conditions. Acoustical analysis software is extremely specialized last I looked into it. The good news is that with most things related to design we don’t have a need for such real world measurements, and relative values work well enough.

Check out the YouTube playlist for VASA here: https://m.youtube.com/playlist?list=PL5DhpoI3HKE99RFSWsxsLVPHGqxQ5TVuc

Autodesk University also has several good resources on the topic which you can find by searching the back catalog, and there was a Dynamo office hour were we discussed VASA posted here: https://m.youtube.com/watch?v=AzazeHjkiUU&list=PLdlF7MirPEC2yNFTGymESd3t7Xosfk9c2&index=5&pp=iAQB

Space analysis is a bit harder to find info on as it is a bit older. However Kean’s blog has quite a bit on the topic: https://through-the-interface.typepad.com/

I really appreciate it.
I will study with the help of what you have introduced.

Thank you so much!
