Listening in Spatialized Noise – Sentences Test (LISN-S)
Developed by the National Acoustic Laboratories and distributed exclusively by Phonak, the LiSN-S is an adaptive, virtual-reality, speech test that measures speech perception ability in noisy environments. Importantly, it also measures the ability of children to use the spatial cues that normally help differentiate a target talker from distracting speech sounds. An inability to use this information has been found to be a leading cause of difficulty understanding speech in noisy environments, such as the classroom.
Offered as a combined hardware and software package, LiSN-S comprises a proprietary PC software program, performance headphones and a USB-attachable Phonak soundcard. Once installed, the LiSN-S system employs advanced mathematical algorithms to create a virtual three-dimensional acoustic space under the headphones.
The hearing professional can simulate different speech environments, with target and distracter voices competing for the child’s attention. By asking a child to repeat the sentences spoken by the target voice, the audiologist is able to accurately assess the child’s ability to identify target speech in challenging situations, like those a child might encounter in the classroom.
LiSN-S is not only accurate but the test is also quick and easy to administer; in just 20 minutes, audiologists are provided with clear results in easy-to-print document format.
LiSN-S is highly sensitive and scientifically robust; its high test-retest reliability allows the hearing professional to test whether a child’s listening skills have improved after some form of intervention. The LiSN-S is available in Australia, New Zealand and the United Kingdom. Norms already exist for people aged 6 to 60 years.
A North American-accented version of the LiSN-S for ages 6 to 60 is currently available in the United States of America and Canada.
A version of the LiSN-S which will be suitable for use with hearing-impaired people is now available from Phonak.
Clinicians wishing to purchase the LiSN-S within Australia can contact Phonak Australia on (02) 8858 1800. Clinicians in North America, the UK or New Zealand can contact Phonak in their own country.
