NOISE MAP IN 3 STEPS
A room’s noise map is a particularly useful graphic element for the analysis and the
choice of acoustic treatments to be implemented, but also for presentations and project
follow-ups. With RAP-ONE, a noise map is rapidly obtained in three steps:
Designing the room
Positioning the noise sources
Calculating the noise map
1) Designing the Room
RAP-ONE rapidly defines the configuration of your room with the help of one-click-
accessible tools to add walls, acoustic barriers, absorbing panels, and fitting areas.
Other functions are used to determine the acoustic properties of the room’s surfaces.
The program can be used for rooms of any shape, the only premise being that the
ceiling and floor are flat and parallel.
By simply using the mouse, the user traces straight lines to define the room’s plan
(image).
To define the acoustic properties of the room, a list of predetermined values is
integrated in the program. You need only to choose the value corresponding to the type
of material that interests you (cement, aluminum, wood, etc.).
2) Positioning the noise sources
3) Calculating the noise map
Note: You may now import bmp files which will be used as a background
image in the current document, making the modeling task easier. In order to
change the position or size of the bmp, activate the bmp mode by clicking on
the bmp mode button on the toolbar.
With the source tool, it is easy to add and position the noise sources on the room
plan. Once this step is done, all that is left to do is determine the acoustic power of
the sources. A source’
s power may be provided by the manufacturer. If not, the
program will assist you in estimating the power with a series of specifically designed
dialog boxes (image).
To obtain the room
’
s noise map: Click on the Noise Map button. In less than a few
minutes, the noise map will appear.
Microphone tool: Move it using the mouse to obtain the exact noise level at the
location where you place it. Also, the rays that contribute to that noise level will be
drawn on the image.
