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

Required Items:
• The Affinity
2.0
hardware
• Licensed AC440 Audiometry module within your Affinity
2.0
hardware
• Calibrated Headphones, insert phones or Free-Field Speakers
Test Procedure
1) Open the AC440 and enter the QuickSIN screen by selecting Menu | Te sts | QuickSIN
2) Select the output level. For the majority of the tracks the channels are synchronised to ensure that
the correct SNR level is achieved. Note: the ‘Speech and Babble’ Lists are not synchronised and will
require the user to manually alter these to ensure the correct SNR setting for the test.
3) Select a list in the corresponding dropdown. e.g. “QuickSIN (List 2)”.
4) Instruct the patient to repeat the sentences and try to ignore the noise that they will also hear
through the headphones.
5) Press START to begin the test
