Investigating acoustic and vibration measurements is set to become much easier

02 June 2009

Designed in close cooperation with the company’s customers already using its PULSE data analysis system, within different industry sectors worldwide, Bruel & Kjaer's PULSE Reflex software comprises three main applications. The first, PULSE Core Time, is a record editing and post-processing analysis tool, which has an efficient -almost limitless - time data handling capacity. This allows the user to edit, filter and study acoustic and vibration results taken inside aircraft, trains or other vehicle cabins.

The PULSE Reflex Modal Analysis tool operates as a guide for users through measurement validation, parameter estimation setup, mode selection, analysis validation and reporting. The results can, for example ,be utilised by engineers for troubleshooting, benchmarking and model validation during the construction of road vehicles, ships or aircrafts.

The PULSE Building Acoustics tool provides fast post-analysis of building acoustic measurements recorded on sound level meters. During planning and construction stages, Architects and builders have to meet industry specified noise parameters, including Loudness (ISO532B) and Noise Rating (NR). Bruel & Kjaer’s 2250 and 2270 meter features these common noise parameters as standard, to ensure users are able to specify the ambient noise levels allowed by the mechanical systems of buildings. Once the field or laboratory conducted sound insulation data has been gathered, the PULSE Building Acoustic software allows the user to measure, review and compare results. The data can also be exported in Excel or Word reports.

PULSE Reflex software enables fast navigation across large volumes of data, rapid filtering or sorting data for further processing, such as statistical analysis, frequency analysis or modal parameter estimation. Users can also include sounds, photographs or videos, which are then linked to items in the project, to provide handy, visual reminders of how - or why - critical decisions were made.
