What are the different types of Speech-in-Noise (SiN) test?
Many different tests and tools exist to analyse and assess SiN ability, such as Hearing-in-Noise Test (HINT), Quick-Speech-in-Noise (QuickSiN), Words-in-Noise (WiN), the Triple Digit Test (TDT) and the Coordinate Response Measure (CRM).
The CRM test has been chosen to assess AFFD for the Police and other command-and-control type organisations because of its clear similarities to real world environments (high face validity), clear focus on auditory skills and ability to differentiate clearly between hearing abilities.
How does a FHAS speech-in-noise test work?
The FHAS test looks to establish the quietest level at which a subject can repeatedly hear and understand a command against a background noise. The test consists for two parts which assess different auditory performance but work in the same way of directing a command in background noise through a headphone in either ear.
Both ears are tested separately but in an innovative interleaved procedure. The subject is required to enter their selection of variables through visual display unit (VDU), e.g. a touchscreen tablet.
What is Quick-Speech-in-Noise (QuickSiN)?
Quick-Speech-in-Noise (QuickSiN) is a Speech-in-Noise test that quickly and easily measures the ability to hear in noise. Speech understanding in noise cannot be reliably predicted from the pure tone audiogram or other standard audiometric tests.
