CARACAD - Floor View to insert Furniture

Select the menu item Load Group in the menu Edit to load a piece of furniture from the CARA furniture data base and insert this into your room design.

In addition you may customize your furniture. A piece of furniture is composed of several 3D objects which finally should be grouped and saved in the furniture data base to make this available for other room designs.
Grouped 3D objects (furniture) can arbitrarily be twisted and moved within the room design. 3D objects are not only used to simulate furniture but also for a widespread field of applications like inside walls, door-frames, window-sills, joists, sloped ceilings, platforms, or false ceilings.

However, you should consider that Calculating Times of e.g. an automatic 'Positional Optimization' will increase excessively with the number of sound reflecting (and absorbing) walls in your room. Therefore do not consider all pieces of furniture or all the nitty-gritty details of your room design. Furniture placed close to the loudspeakers or the listener have a larger impact on Sound Coloration than those on more distant places. The same holds for large pieces of furniture in comparison to smaller ones.

In addition, the new CARA 2.1 PLUS function 'Acoustic Ambiance' evaluates the basic acoustic properties of your sound room and suggests some means to improve the basic acoustic behavior. For this a more detailed room design may be used since these evaluations are based on 'classical' calculation methods which are much less time consuming.
Therefore a two step room design procedure is recommended:

Create a detailed room design, making sure to include all furniture and material surfaces. The details are important in the analysis of the Acoustic Ambiance.
Create a simplified room design containing only simple models of major pieces of furniture. The calculations that run to determine sound fields and optimum positions for your loudspeakers and listeners rely less on the details and a more simplified design will have a much shorter calculating time without a significant decrease in accuracy.
