What is AuditStore™?
AuditStore is a new technology that helps you to ensure that your noise measurement data is valid and trustworthy. AuditStore allows the user to verify measurements that have been downloaded to the NoiseTools software against a secure data store within the instrument.
This allows the user to present data with confidence and to have the facility to verify that the measurement data has not been modified or adjusted.
The AuditStore technology is available, as standard, on all optimus sound level meters with firmware version 2.4 or later (March 2012). Downloading the AuditStore data requires NoiseTools version 1.4 or later.
How is AuditStore useful?
When you make a noise measurement with your optimus, the information about the noise levels are stored in your sound level meter.
When you download this information your PC using the NoiseTools software, the data is stored in a database. This information can be used to print out a report which may be used to show compliance with standards or regulations. When you present the data as a printout or a PDF for example, how can you guarantee that the information shown is the same as that which was originally measured by the sound level meter?
With the software that is available on PC’s, it is possible to manpiulate data or create what appears to be a noise measurement report with data that has been changed.
The AuditStore function allows you to verify your measurements and to state that the information being presented is true and has not been adjusted in any way.
