The STIPA analyzer option allows durable and reliable speech intelligibility measurement within 15 seconds (typical). Besides the single value STI or CIS test result, a detailed view of modulation indices and individual band level results is provided. The STIPA analyzer includes amplitude weighting in accordance with the 2003 IEC 60268-16 standards release.
A designated STIPA test signal is provided by the Minirator MR-PRO or the supplied Test-CD.
Acquired measurements may be referenced to previously-established background noise level spectras with automatic recalculation of the STI values.
