ISO Standard It is necessary to use standard methods for frequency weighting so that results from different measurements, using different equipment, can be compared. The design and processing of data with a supported frequency weighting filter is accomplished in one easy step. Follow these links to find other Standards similar to the one you are viewing. In addition the ISO Wh and British BS Wg frequency weighting filters are included to provide a complete, standards-based frequency weighting solution.
Both an interactive dialogue box interface and simple command line functions are provided. Key features Simple dialogue box user interface.

Guidelines for the evaluation of the effects of vibration and rotational motion on passenger and crew comfort in fixed-guideway transport systems This document has been re-assessed by the committee, and judged to still be up to date. It is used for crew and passenger exposure to vibration in rail vehicles, or fixed-guideway transport systems. It is necessary to use standard methods for frequency weighting so that results from different measurements, using different lso, can be compared.
The Wb weighting factor is defined in ISO You have definitely made my day!
