1.7.18 SIQ test

The Speech in Quiet (SIQ) test is a method of testing a patient's f unctional hearing in the absence of any
competing sound. The objective of this is to identif y their f unctional hearing ability (Schoepf lin, 2012). The
outcome of this investigation will give a Speech Recognition Threshold (SRT).
This type of testing is dif ferent f rom Tone Audiometry as it involves higher areas of the Auditory pathway as
the inf ormation needs to be heard, processed, and repeated to give a correct response (National Research
Council (US), 2004).
The SIQ test is designed to be perf ormed via loudspeaker as it is a f ree f ield test. However, it can be
conf igured to perf orm monaurally via selection of headphones and routing the signal to the relevant ear-side.
The SIQ test is very similar to Speech Audiometry and can use any of the materials you have already ripped
into your Interacoustics Suite sof tware. However, the Stimulus intensity is maintained automatically by the
sof tware f ollowing a correct or incorrect response to the stimulus, this helps to speed up the test time.
When should I perform the SIQ test?
It is normal to perf orm this f ollowing Tone Audiometry as it gives a good indicator of the patient s
perf ormance f or speech, it can also be a good indicator of the accuracy of your audiogram (Mehta & Singh,
2000). It can also be used bef ore and af ter the provision of hearing aids to give an identif ication of the benef it
achieved through amplif ication.
Test procedure
1. Launch the Af f inity
2. Click on the AUD tab on the upper right-hand side of the screen. Ensure that your Audiometry has
been perf ormed ahead of advancing into the SIN test as this determines the start level f or the test.
Click on Menu, Tests and then select SIQ
3.
4. Once in the SIQ test screen, the stimuli levels should be set f or you. These are based on the patient
audiogram and the PTA score.
