QuickSIN
Pronunciation: kwik-SIN
A standardised clinical test (Quick Speech-in-Noise) that measures a listener's signal-to-noise ratio loss using sentences presented at varying SNR levels against a four-talker babble background.
Full Definition
The QuickSIN (Quick Speech-in-Noise) test, developed by Etymotic Research, measures a patient's ability to understand IEEE sentences embedded in four-talker babble at signal-to-noise ratios ranging from +25 to 0 dB SNR in 5 dB steps. The result is expressed as the SNR loss in dB relative to normal-hearing performance, allowing audiologists to quantify the real-world hearing difficulty that a standard audiogram may underestimate. Editors should note the distinctive capitalisation ('QuickSIN'—no space, capital S, capital IN) and the fact that it is a registered test tool name. It should not be used as a generic term for speech-in-noise testing.
Usage
Usage note: Preserve the trademark capitalisation 'QuickSIN' (no space). Do not use as a synonym for all speech-in-noise testing. Results should be reported as dB SNR loss.
