4) Acoustic design software
There are a variety of software that can be used to develop concert hall models. Of course there must be a first part of three-dimensional modeling of the room, and then move on to specific programs that study the sound effects inside the hall itself.
It is a basic CAD software, for three-dimensional modeling, capable of managing complex surfaces and calculating different geometric characteristics of them. It is able to manage complex shapes and geometries thanks to N.U.R.B.S. (Non Uniform Rational B-Splines); all geometric entities are represented by N.U.R.B.S. Quite simply, the N.U.R.B.S. they are a mathematical representation by which it is possible to accurately define 2D and 3D geometries such as lines, arcs and free-form surfaces.
Python, a Rhinoceros plug-in, is a programming language, suitable for building applications quickly, and is used for a wide range of purposes: scripting, creation of complete programs, prototyping of applications that will then be rewritten in other languages. The script is a small program or application, written within another more complex software, capable of giving instructions and commands to the program in a specialized and personalized way.
In the case of acoustic design, scripts can be written within Rhinoceros thanks to Python, in such a way as to better customize the shape you intend to give to the room under study.
Pachyderm Acoustic
It is another plug-in that provides professional-level tools for acoustic analysis and simulation with Rhinoceros. Perhaps the most innovative feature of Pachyderm over other software comes from the fact that it was designed as an integrated component of Rhino. If the modeling phase and the acoustic simulation phase, usually separated between two different software, both remain within the same platform, the workflow will be positively affected, in terms of time and in terms of model quality.
Grasshopper is an additional plug-in that runs inside Rhinoceros and is a visual programming language, mainly used to build parametric models.
Grasshopper allows you to organize projects in parametric systems, based on relationship logics between parts, offering the possibility of altering the overall configuration of the system, acting on the variables at the basis of the design process.
Grasshopper also allows you to integrate variables and heterogeneous aspects in a single process, focusing on the network of relationships, flows and exchanges that the project establishes with the surrounding systems. These aspects constitute a real evolution in architectural research.
