PRO-280: Sound Power / ISO 9614
Sound Power fitting ISO 9614 Part 1 & 2
NetdB-PRO-280: Intensity based Sound Power measurements
An efficient 2-channel turn-key solution fitting the ISO 9614 standard (Part 1 & 2) to measure the sound power characteristics of your products.
First introduced in 1996 with a dedicated and powerful software 01dB-Metravib' solution for Sound Power determination using Sound Intensity has been very successful.
Now labelled PRO-280, this system integrates the ISO-9614 standard and is made available as a dedicated package supporting dB4 platform to meet customers' needs for handy operation in field or laboratory conditions:
- Very flexible
- Most accurate
- Full control of ISO 9614 check parameters
Key Features
Easy to operate and flexible
- User guiding for a total support in Sound Power determination process
- Portable and Battery Operated
- Pre-formatted Results Data table for immediate reporting
- ISO 9614 parameters check and errors handling with on-line tutorials and suggestions
- Pressure and Intensity mapping
- Calibration in amplitude and phase allowing use of different kind of Intensity probe types
Options
The PRO-280 package of hardware and software integrates the definition and execution of the power measurement and the related quantities such as:
- Calibration check by inverting the probe
- Stationarity check of the sound field for the point per point method
- Integrates the dynamic calculation (during measurement) of criteria that enables validation of measurement results
Sound Intensity calibrator & calibration software are proposed as options.
PRO-280 is robot operable for increased efficiency on systematic evaluation of sound power characteristics of various test devices
Applications
Automotive, Motorbikes, Aeronautics, Railway, Ships, Space, Construction Machines, Building industry (Ground Vibrations, Environmental Data), Electric appliances/IT, Household appliances, Medical (Electro-testing, Encephalography, Electrocardiography, Electromyography)
