Sound Power version 3.20 can be downloaded here: \\SYNO\soft-publish\versions\SoundPower\_val\2021-04-07 SoundPower_V3.20_059594

New functions

New commands available

New commands are available to customize the start of Sound Power. They can be used in cmd (right after the commande SoundPower.exe) or also changing the Sound Power shortcut properties:

All the commands can be combined together, for example: SoundPower.exe -project=myProjectName -setup="C:\OROS\Sound Power data\Setups\mySetup.xls" -nvgarg="online -ListHardIpAddr=223.255.253.50 -silent"

The commands are detailed in the following sections.

Start SP with a predefined project

-project=myProjectName

Start SP with a predefined setup

-setup="C:\OROS\Sound Power data\Setups\mySetup.xls"

Start SP directly in the connected mode

-nvgarg="online -ListHardIpAddr=223.255.253.50 -silent"

With this command the NVGate start window is skipped. Sound Power will start NVGate directly in the connected mode. The analyzer's IP address must be mentioned. With the optional argument -silent, NVGate splash screen will not be displayed.

The same command can be used to start SP in office mode: -nvgarg="office"

Allow OROS Drive

-orosdrive=4006
Orosdrive enables the use of further commands to drive SoundPower with an external program. Contact OROS Customer Care for more information.

User identification

It is possible to skip the user identification: the SoundPower.usr file has to be modified for that. You can download a modified SoundPower.usr file here. It should be placed in both NVGate and SoundPower folders.

How to modify SoundPower.usr?

In NVGate folder, rename SoundPower.usr in NVGate.usr. Start NVGate. In the General preferences, activate "Skip user identification". Close NVGate. Rename NVGate.usr in SoundPower.usr. Copy SoundPower.usr in the Sound Power folder.

Restricted mode: SP operator cannot save the changes made in an existing setup. If any changes are made in the setup, they will not be saved when leaving SoundPower. This is thought to secure the setup and avoid any overwriting issues by mistake. It is anyway possible to switch user during the SoundPower session (click on user/change...). If you switch to the user SP manager, you then have the possibility to save the setup.

Frequency range for the overall level

The new function of NVGate 2021, allowing the user to choose the low and high frequencies for the overall level computation in OCT Plug-in has been integrated in Sound Power. This settings can be found in the Setup Browser, under K correction / Frequency range / Sound Power level. If you are using a setup built with a previous version, the settings cannot be modified but the measurements can be performed anyway. Contact OROS Customer Care to adjust the setup to enable the modification of the frequency range. In C:\OROS\NVGate data\Projects, replace also the Sound Power project with this one.

Note: In some cases the use of this function is not possible, due to DSP limitation (mostly for OR34 and OR35 equipped with only 1 DSP). An error message is displayed when loading a setup or connecting the microphones (NVGate failed connecting input...). It is necessary to revert to the previous Sound Power project.

Update of the Excel templates

The Sound Power templates delivered with Sound Power software have been updated:
- previously, the K2 max value was 2. To comply with ISO 3744:2010, K2 max value is now 4.
- addition of the absolute criteria for the background noise (ISO 3744:2010, Section 4.2.2). If the background noise measured in the room is lower or equal to the spectrum given in the standard and the source level is above this spectrum at each frequency band, the background noise condition is fulfilled.
