Pachyderm Acoustic

Pachyderm is a plugin largely used by Designers and Scientists alike to simulate acoustics in buildings, rooms, cities, and other settings.

  • Use pachyderm for street noise analysis and optimization of planning and building geometry solutions?

    Hi - Is Pachyderm only for interior acoustic analysis or can I use it to test impacts of street noise? I am trying to position and shape 3 story residential buildings, with possible insertion of sound barrier walls or berms and enhanced wall insulation and reduced window sizes, to reduce negative…

  • Pachyderm does not load

    Hi, I loaded Pachyderm into Rino 7 and tried a simple model in a box and it immediately crashed Rhino. I cycled through that a few times with the same result. I off loaded Rhino 7 and re-loaded Pachyderm to no avail. I then purchased Rhino 8 and cycled through the same problem. Now Pachyderm will…

  • Acoustical Analysis of an Outside Space

    Hello everyone,I run often in some Problems with the analyisis of the outside space.It often makes an invisible Space where the soundwaves bounces of from even tho that Space doesnt exist in the Modell.Could anyone help?Sorry for the WeTransfer Link but somehow the Modell is to Big…

  • Multiple sound sources simultaneously

    Hi all, I would like to have 3 sound sources emitting sound simultaneously. I can input 3 sources, but I could only get measurement from the receiver for each of the sound sources respectively. Instead, I would like to have one measurement for the three source points. Does anyone know the way?Thanks

  • Particles colour in simulation

    Hello everyone!I set the particles to downgrade from red at the beggining (a hot colour) to blue at the end (a cold colour), but when I run the simulation some of the first frames turns from red to a kind of purple and then red again. My deduction is that some of the old particles crash with some…

  • Absorption designer

    Hello everyone. I am trying to get the absorption coefficient of an element with the "Call absorption designer" in PachyDerm_Acoustic - Pachyderm Hybrid Models. When I set a Porous material + Solid plate or Perforated material it gives me a result about the absorption level in all frequencies; but…

  • Sound Simulation_ Reverberation Time calculation_Inconsistant Results

    Good morning all,I am currently working on the calculation of the reverberation time of different closed spaces. I have a closed geometry (simplified model of the Hypogeum in Malta), and what I did was change the scale of it, so I had 3 versiones in: 1:1 / 1:2 / 1:5. What caught my attention was…

  • Real Time Auralization

    Dear all, for those of you interested in real time auralization, I recently made this GH file to use the outputs from the Pachyderm image source tracer to send auralization data to Max-MSP and Spat-5 via UDP/Firefly.It can handle up to 64 reflections and sends to Spat-5 the levels for direct, early…
