Fourth generation sound analysis hardware from Brüel & Kjær

September 2012 -- Sound and vibration specialist, Brüel & Kjær has launched a fourth generation of hardware for its sound level meters and hand-held analyzers - Types 2250 and 2270 G4.

This new hardware enables Types 2250 and 2270 users to run multiple, upgraded applications, such as frequency analysis, logging and signal recording. It also has a high-contrast colour screen, which makes performing outdoor measurements easier for environmental officers and consultants.

The Type 2270 G4 meter provides users with dual-channel capabilities, such as sound intensity for noise source location measurements in vehicles, sound power for testing consumer goods or machinery during development and building acoustics tools, which can be used for measuring sound insulation inside structures. The new hardware has boosted the meters’ processing capabilities for faster calculations and increased battery life.

All Type 2250 and 2270 instruments running version 4 of the instrument software can interface directly with Vaisala ultrasonic weather stations, which allows seamless integration of noise and weather data within the sound level meter, so wind affected noise measurements are easily identified.

GPS devices (Global Positioning Satellite) can also automatically record the measurement location, making it simpler to link noise levels to particular areas during the post-processing stage.

Brüel & Kjær has also transformed its Sound Level Meter PC software BZ-5503 - a post-processing PC software application for all Type 2250 and 2270 meters. BZ-5503 Measurement Partner Suite allows users to download, view, post-process and archive noise and weather data in one PC application.

The most common post-processing tasks are available in a graphical environment, designed for noise level analysis. This eliminates the need for repetitive and time-consuming exportation of data to spreadsheets. Existing BZ 5503 users can download the new Measurement Partner Suite for free on Brüel & Kjær’s website.
