QuickSIN test
Difficulty with hearing in background noise is a common complaint among hearing aid users. Therefore,
the measurement of SNR loss (signal-to-noise ratio loss) is important because a person’s ability to
understand speech in noise cannot be reliably predicted from the pure tone audiogram. 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
TM Speech-in-Noise Test
manual, version 1.3.
Only available if High Frequency is available (optional license) on the AD629.
Selects the HF phone connected to the separate HF connectors.
Different lists can be changed in the “List” option. Use the HL dB dial (41) to
select the different items in the lists.
