Improved software for hand-held analyzer users

Update includes 24-bit recording, remote functionality and usability enhancements

November 2012 -- Sound and vibration expert Brüel & Kjær has launched a software update for its hand-held analyzers - Version 4.1.

Designed for the company’s 2250, 2270 and 2250 Light hand-held analyzers - and their PC software ‘Measurement Partner Suite’ - the new version 4.1 is the first feature update of Brüel & Kjær’s fourth generation (G4) hardware and software, which was launched in April 2012.

The updated software is packed with useful features and functionality: for remote instrument use, improved notifications send daily SMS or emails relaying the instrument’s status and potential problems, such as tampering or damage. A noise threshold exceedence notification alerts users when preset noise limits are exceeded.

24-bit signal recording is now available - which allows users to easily record complete data without the risk of overloads - and subsequently perform post-processing on WAV files. 16-bit resolution is also still available.

The software provides a moving (or sliding) average of the latest T minutes (1 to 60 minutes) that updates every second, making it ideal for monitoring sound exposure at outdoor events like concerts and festivals.

New features in Measurement Partner Suite include background noise correction according to commonly used standards, playback of 16- and 24-bit recordings, and display of noise rating curves (NR, NC, and RC).

The 4.1 release is available for download here:
