OVERVIEW

 

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 Symphonie platform to meet customers' needs for "handy" operation in field or laboratory conditions:

bulletVery flexible
bulletMost accurate
bulletFull control of ISO 9614 check parameters

Main functions

Easy to operate and flexible

bulletUser guiding for a total support in Sound Power determination process
bulletPortable and Battery Operated
bulletPre-formatted Results Data table for immediate reporting
bulletISO 9614 parameters check and errors handling with on-line tutorials and suggestions
bulletPressure and Intensity mapping
bulletCalibration 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:

bulletCalibration check by inverting the probe
bulletStationarity check of the sound field for the point per point method
bulletIntegrates 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
