111 HOTTINCER WWM BRUEL & KJ/ER BRUEL&KJ^R® Data Analysis SoftwareBK Connect Loudness and Overall Analysis Applets BK Connect® applets are for customers looking for a point solution that works like they work, providing just what you need in a user-friendly solution. The applets provide the same reliability and thought-through design of an advanced sound and vibration analysis software platform, in a small, self-contained package. The BK Connect Loudness and Overall Analysis applets are specifically for standard sound tests using the ISO 532-1 loudness calculation and overall analysis on both stationary and non-stationary signals. There are two applets that provide full loudness and overall analysis testing solutions to help you complete the job at hand: • Type 8490-D - Go from data acquisition and monitoring to measurement, recording, analysis and reporting • Type 8490-I - All-in-one solution for post-processing of time data, data management and reporting Uses and Features Uses Type 8490-D - Applet for acquisition, recording, batch postprocessing, data management and reporting • General sound data acquisition, analysis and reporting • Time data recording • Batch processing of multiple sets of time recordings • Broadband overall analysis for characterization of noise • Stationary and non-stationary analysis • Analysis with different filter settings and resolution of the loudness calculation bandwidths • Loudness for impulsive events and BSR (buzz, squeak and rattle) Type 8490-I - Applet for batch post-processing, data management and reporting • General sound analysis and reporting • Batch processing of multiple sets of time recordings • Broadband overall analysis for characterization of noise • Stationary and non-stationary analysis • Analysis with different filter settings and resolution of the loudness calculation bandwidths • Loudness for impulsive events and BSR (buzz, squeak and rattle) Features • User interface, task completion and data organization optimized to fit the job at hand - with tools and components that make acoustic analysis quick and easy • Simultaneous multi-analysis of the same recorded data -loudness according to ISO 532-1 including statistical percentiles 5%, 50% and 90%, and overall analysis • Visualization, editing and audio playback of time data after recording and in preparation for analysis • Simple and efficient reporting of results with user-definable layouts metadata • Embedded reporting using Microsoft® Office products to integrate report creation directly in the test process • Easy to learn and use, reducing training and test time

About BK Connect Loudness and Overall Analysis Applets With Type 8490-D, you can record and perform loudness and overall analysis in one seamless workflow. A complete set of real-time monitors is preconfigured and a targeted process (analysis) chain is predefined – ready for you to start analysis. If needed, you can adjust monitor parameters and analysis properties to suit your test specifications. When ready, record data using the simple recorder located in the monitors. Using the same predetermined processing and analysis tools as Type 8490-D, post-processing applet Type 8490-I allows you...

Using the Applet The practical and user-friendly interface provides automated batch processing of data, immediate display and storage of analysis results and automated reporting. Fig. 2 Processing in the Loudness and Overall Analysis Applet Automated Operations The applets’ many automated operations makes it easy for the novice user and is perfect for repetitive testing: • Auto-detection of hardware – The software will automatically detect connected LAN-XI data acquisition modules and TEDSenabled transducers • Data source management– Select a default data source for processing, the software...

SUPPORTED DATA FORMATS Result Matrix Viewer The Result Matrix Viewer provides a structured overview of results from a large number of tests, making selection and comparison very easy: Data Management Data management is based on a data model that interacts with a Microsoft® SQL Server® database. Connection to the last used database is automatic upon starting BK Connect. However, the user can connect to a different database at any time during a session. Only one database can be connected at a time. Local database with each BK Connect installation; optionally accessible via a BK Connect...

Reporting A separate reporting task enables templates to be created in Microsoft® PowerPoint® Hardware Setup Features Specifications - Type 8490-D-N-SYS Only HARDWARE SUPPORT Hardware Configuration The software automatically detects the front-end hardware and configures the system. If IEEE 1451.4 capable transducers (with standardized TEDS) are being used, these are detected and attached automatically to the correct input channels Hardware Browser The Hardware Browser combines the Hardware Matrix and HW Setup Table that work together to provide a highly efficient way to work with any size...

Generator Setup Transducer Manager The Transducer Manager works with a Microsoft® Access® database (as used by PULSE LabShop) to manage transducer specifications and calibration information Real-time Monitor Transducer Verification Transducer Verification can be used either to verify that transducers are functioning correctly, or to make a new calibration A transducer calibrator is used to apply the necessary excitation for either verification or calibration. Multiple calibrators can be used simultaneously. The software automatically detects the calibrator signal and performs the...
