Noise Studio is a post-processing program that can perform sound analyses in compliance with current Italian and European Community norms. The analysis functions are grouped in software modules that can be enabled using a licence.
The analysis environment gives several display functions (as a table or graphically) of the different sound measurements and processed results. All graphs and tables can be exported to other applications in the Windows® environment. The analysed data and results can usually be stored as Workspaces, together with other documents, so as to allow future checks and analyses.
You can process both the data downloaded from the sound level meter memory and the data captured directly by the PC's memory using the Monitor program.
The "Sound Insulation" module was designed to determine the passive acoustic requirements of buildings in agreement with D.P.C.M. of 05/12/1997.
In particular, it manages measurement and calculation of:
average reverberation time
equivalent absorption area / absorption coefficient
airborne noise insulation between two rooms (R, R', DnT indices)
façades and relevant elements' insulation (Rtheta and D2m,nT)
ceiling impact noise insulation (Ln, D, L'n, L'nT)
A summary guide accompanies measurements taken in agreement with ISO norms.
The software includes a database of walls and ceilings with relevant indices and frequency behaviours.
This software works in conjunction with the HD2010 and HD2110 sound level meters equipped with the reverberation time measurement option.
To launch the program, double click on the NoiseStudio icon using the
left button of the mouse
or click Start and select All Programs >> Delta Ohm >> NoiseStudio.
This program, once started for the first time, asks
for an activation hardware key, otherwise it works under Demo condition.
Under this condition all the software functions are enabled but you can
only use the exmples files as input data, which are available in the CDRom
NoiseStudio - Sample Files (D:\Esempi\IsolamentoAcustico\).
In order to get the hardware key for the module activation, please contact your distributor (HERE below are the details).
When you start the program, the main window will open with the following control panel: Main Menu and Toolbar.
NoiseStudio uses the data acquired by the sound level meter and calculates
the coefficient which evaluates buildings' passive acoustic requirements
according to ISO norms. Analysis of a building requires various measurements.
These can be grouped inside one "container" so as to simplify
their filing and retrieval.
Moreover, in addition to actual measurements, it may be useful to have
a technical report, some comments,... or graphs, illustrations,... being
an integral part of the job and that could easily be recovered if required.
This "container" is the Workspace.
 |
To start a new Workspace, press New Workspace: the data analysis window opens. |
Select the type of measurement and press OK.
The program will ask if you wish to create a project or open an existing one.
In the following example, the project was called "Example".
The measurements concerning average reverberation time and/or equivalent absorption area are grouped under the Reverberation Time item.
Perform the selected measurement as reported below.
On being saved, the measurement is added to the measurements making up the project:
Similarly, you can add new measurements to the Workspace:
| using the Start Analysis key |
 |
| or, if the measurement is already open, |
|
| using the Add file to Workspace key. |
 |
| To remove a measurement in the Workspace, select it and press Remove file from Workspace. |  |
The Documents item collects all text documents
("doc" extension) such as technical reports, notes,
... which have been entered by the user.
To add an existing document double-click on Documents. A window
will open to select the file to be inserted.
To create a new document, double-click on Documents, enter the
name assigned to the file, and press OK. The application linked to the
extension "doc" (e.g. WordPad) is started: edit the text and
save the file. Upon closing editor, the new document is saved to the Workspace
and appears in the Workspace window.
The Pictures item behaves similarly, and collects image files with "bmp" and "jpg" extensions. The display application is that associated to the "bmp" and "jpg" extensions, respectively (e.g. PaintBrush).
The Miscellaneous item, collects all the files that are not included in the above categories: e.g. "pdf" extension files (Adobe Acrobat), "zip" compressed files, ... etc.
Please note that each time a new item is added to the Workspace, the correspondent file is copied in its folder.
The list of measurement types managed by the software is shown in the Analisys >> Acoustic Insulation >> Start Analisys menu item.
Each item is accompanied by a description of the measurement it refers to: press INFO to access it.
The reported description does not replace the norm details but briefly describes its essential points: to proceed with the measurement it is recommended that all needed operating information is directly acquired from the reference norm.
The measurements available are the following:
Laboratory measurement of the impact-noise insulation coefficient Ln
On site measurement of the impact-noise insulation coefficient L'n, L'nT
Average reverberation time is a basic parameter in building acoustic measurements.
It is obtained from the average reverberation times, frequency by frequency, measured in different room points and with the source in various positions.
Starting from a series of measurements acquired by the sound level meter with reverberation time measurement function, the NoiseStudio software calculates the average value of one of the EDT, T10, T20 or T30 parameters.

In the window that opens, input the wall or ceiling attenuation characteristics, the C and Ctr coefficients and a name to identify the new element in the database.The Rem key removes the selected item from the database.
The opened database item can be:
exported to Excel (File >> Export to Excel),
copied to clipboard (Tool >> Copy to Clipboard) or
printed (File >> Print).
This function allows comparing up to five evaluation indices curves.
The curves can be input using the Add key, getting the data from already saved files or imported from the database using the Add DB key.
To remove a curve, select it and press Rem.
The data collected in the comparison window can be
exported to Excel (File >> Export to Excel),
copied to clipboard (Tool >> Copy to Clipboard) or

is supplied under DEMO condition.
Under this condition all the software functions are enabled but you
can only use the sample files as input data, which are availabe in
the CDRom NoiseStudio - Sample Files (D:\Esempi\).
If you have the basic version of the software without modules and you wish to buy the user license for one or more modules, please contact your distributor. The software will be supplied along with the proper key already activated: in order to use the module, it is necessary that the hardware key is pluged into a USB port of the PC.
If you already have one or more activated modules with proper hardware key and you want to buy another one:
press key "Activate module",
Contact your supplier and give him the code of the module you should purchase.
Once you have the file, plug the key into a USB port of the PC and press the key "Update key": select the file received by the supplier and confirm with OK. The hardware key will be updated with the new module.
To speed up the use of the system, some operations accessible trough the menus are also located on the command bar immediately beneath the main menu in the form of buttons.
