SHOEBOX PureTest automatically calculates standard threshold shifts against established baseline audiograms using OSHA and MSHA methodologies immediately upon test completion. The calculation compares the average of current thresholds at 2,000, 3,000, and 4,000 Hz to baseline thresholds in each ear. Age correction using Appendix F tables can be configured by the administrator and applied automatically.

The calculation compares the average of current thresholds at 2,000, 3,000, and 4,000 Hz to baseline thresholds in each ear. Age correction using Appendix F tables can be configured by the administrator and applied automatically. STS detection operates offline — the current audiogram is compared against the downloaded baseline without requiring an internet connection. The STS result syncs to the Data Management Portal when connectivity is restored, where it triggers the portal’s triage and routing workflow.
