How to perform QuickSIN with Equinox Evo

Equinox Evo Support

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 SNR 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.

Licensed AC440 Audiometry module

Calibrated headphones, insert phones or free-field speakers

Open the AC440 module and enter the QuickSIN screen by selecting Menu | Tests | QuickSIN.

Select the output level. For most 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.

Select a list in the dropdown.
