SoundPower

Software for determining the sound power level according to ISO 7779, ISO 3744, ISO 3745, ECMA-74

SoundPower is an extremely elegant and user-friendly software solution for a standard-compliant determination of the sound power and sound pressure level. Hardware manufacturers are legally bound to state the sound power of their devices according to international standards if they are to be sold within the EU. By means of wizards, users of SoundPower are guided through the standard procedures that comply with the international stantards to fulfill the legal requirements quickly and reliably.

Futhermore, SoundPower offers user-specific measurement procedures that go beyond the standard procedures. Apart from assuring the compliance with standards SoundPower also offers the measured time signals for playback and or advanced analyses with the analysis software ArtemiS.

  • Standards-compliant determination of sound power and sound pressure levels of, e.g. office, IT, telecommunication devices and household appliances
  • Sound Design, troubleshooting and quality control
  • Safe proceeding with wizards guiding the user through the measurements and calculation procedures
  • Convenient project management using cross-project templates in order to avoid unnecessary measurement repetitions
  • Time-saving work thanks to the storage of calibration data, measurements of background noise and environment correction values for other projects
  • Quick measurement preparation thanks to automatic front end detection and convenient sensor calibration
  • Precise measurement control via playback of the audio signal
  • Easy detection of creeping changes of the measurement setup by means of a calibration and measurement history
  • Customization by user-specific cutting of audio signals
  • Good overview thanks to the presentation of all individual measurements in one window, so entire series of measurements can be compared at a glance
  • Additional benefits by exporting audio signals to ArtemiS for the optimization of sound quality
  • A wide range of custom documentation possibilities thanks to automatic report generation in Microsoft® Word

Standards-compliant determination of the sound power level:

  • ISO 7779 1999 - Determination of sound emissions of office and IT equipment
  • ISO 3744 1994 - Acoustic determination of sound power levels of sound sources by means of sound pressure measurements Procedure with accuracy class 2 for a mainly free sound field above a reflecting surface.
  • ISO 3745 2003 - Acoustic determination of sound power levels of sound sources using sound pressure measurements Procedure with accuracy class 1 for anechoic chambers and hemi-anechoic chambers.
  • ISO 11201 1995 - Sound emissions of machines and devices.
  • Measurement of emitted sound pressure levels at the work place and other specified locations. Procedure with accuracy class 2 for a mainly free sound field above a reflecting surface.
  • ISO 9296 1988 - Agreed sound emission values for computer and business equipment

The relevant value specifying the sound emission of a device is the sound power level, whereby ISO 779 sets the framework for the procedure. For the actual measurement of the sound power level, this procedure refers to several measurement standards.

The standards Norm ISO 3745 and ISO 3744 define specific methods for determining the sound power level. The enveloping surface procedure according to ISO 3745 for anechoic and hemi-anechoic chambers complies with accuracy class 1. User may also choose to apply the enveloping surface procedure according to ISO 3744 which has been established as the standard method (accuracy class 2). ISO 3744 describes how the emissions of a single device in a mainly free sound field above a reflecting surface are measured and how the sound power level is determined. In addition, ISO 7779 specifies the measurements of impulsive noise and tonality.

Also, the sound pressure level according to ISO 7779 has to be measured for the specified positions of the operator and bystander. For this purpose, ISO 7779 refers, among others, to the standard measurement procedure (with accuracy class 2) defined in ISO 11201. In order to assure the comparability of the sound power levels also for several devices within one production series, the declaration of the sound power level must follow defined, statistic procedures according to ISO 9296.
