Data analysis: post-processing software simplifies task

21st February 2013


Investigating acoustic and vibration measurements is said to become much easier with Brüel & Kjær's new post-processing software, which is known as Pulse Reflex. Designed in close co-operation with the company's customers already using its Pulse data analysis system, Pulse Reflex comprises three main applications. The first, Pulse Core Time, is a record editing and post-processing analysis tool, which has an efficient and 'almost limitless' time data handling capacity. This allows users to edit, filter and study acoustic and vibration results taken inside areas such as 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.

Pulse Building Acoustics 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 (ISO 532B) 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 users to measure, review and compare results. The data can also be exported in the form of Microsoft 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
