Reinvigorate your APD test battery

LiSN-S is a breakthrough in the acoustic assessment of children. The first public tool of its kind, LiSN-S allows clinicians to measure how well a child uses the spatial information in sound to understand speech in noise. As inability to use this information has been found to be a leading cause of auditory processing disorder (APD).

Developed by Dr. Sharon Cameron and Dr. Harvey Dillon of National Acoustic Laboratories of Australia (NAL) and distributed by Phonak, LiSN-S enables the audiologist to simulate a range of different noise environments (see LiSN-S Test Conditions). Quick to administer, scientifically robust, and with high test-retest reliability, LiSN-S revolutionizes auditory testing for children.

Introducing LiSN-S

How to administer LiSN-S


“LiSN-S is an excellent example of a new generation of well-designed, evidence-based clinical measures of auditory-specific processing. LiSN-S taps into critical auditory processes that are not evaluated by the existing APD test battery.”
