3.7.1.9 QuickSIN test (optional)
The QuickSIN test was developed to provide a quick estimate of SNR loss. A list of six sentences with five
key words per sentence is presented in four-talker babble noise. The sentences are presented at pre-
recorded signal-to-noise ratios which decrease in 5-dB steps from 25 (very easy) to 0 (extremely difficult).
The SNRs used are: 25, 20, 15, 10, 5 and 0, encompassing normal to severely impaired performance in
noise. For more information please refer to Etymotic Research’s QuickSIN
