Quick Guide to QuickSIN -
The purpose of this document is to provide a quick guide and an overview on using the Callisto™ system to
perform QuickSIN testing.
The QuickSIN test was developed to

Provide a one-minute estimate of SNR loss

Provide a quick way for clinicians to quantify a patient's ability to hear in noise

Determine if extended high frequency emphasis improves or degrades understanding of speech in noise

Assist professionals in choosing appropriate amplification and other assistive technologies

Demonstrate that hearing aids with directional microphones improve speech intelligibility in noise

Provide a large number of equivalent test lists for use in clinical and research work

Provide information useful in counseling patients regarding realistic expectations
QuickSIN for the AUD440 Module

To enable QuickSIN testing from your Audiometry Screen select:
Menu →Test->QuickSIN

Transducer: QuickSIN can be performed using the headphones (right or left
ear) and through the Callisto speaker. Please select Right, Left or FF1
(speaker) from the drop down list in Channel 1. (Please note: the Callisto
speaker is not calibrated for free field testing, therefore the intensity should not
be used for diagnostic reporting – the Callisto™ speaker can be used to
compare Aided vs Unaided or demonstrate SNR loss testing at an uncalibrated level)

Presentation Level: You may choose your own preferred test level. (Recommendation: 70dB HL level for
a client with a pure tone average of 45dB or below. For pure tone average above 50dB HL, we recommend
a level judged to be loud, but not discomforting, for your client).
Select 'Extended Range'
Increase intensity to 70dB or preferred level – for FF1 (speaker)
testing please increase to around 78dB with the speaker placed
around 50 cm away from client.

Patient Instructions: "Imagine that you are at a party. There will
be a woman talking and several other talkers in the background.
The woman's voice is easy to hear at first, because her voice is louder than the others. Repeat each
sentence the woman says. The background talkers will gradually become louder, making it difficult to
understand the woman's voice, but please guess and repeat as much of each sentence as possible."
may help to stress to the client to repeat what they have heard, even if they have only heard one word from the sentence as
this may improve their score.

QuickSIN Methodology: 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.
