Sonification Method to Enhance the Diagnosis of Dementia
MetadataShow full item record
Positron emission tomography (PET) scans of brains result in large datasets that are traditionally analyzed using visual displays and statistical analyses. Due the complexity and multidimensionality of the data, there exist many challenges in the interpretation of the scans. This paper describes the use of a sonification method to assist in improving the diagnosis of patients with different levels of Alzheimer’s dementia. A tripletone method is introduced, and the audible beating patterns resulting from the interaction of the three tones is explored as a metric to interpret the data. The sonification method is presented and evaluated using subjective listening tests. Results show the triple-tone sonification method is effective at evaluting PET scan brain data, even for listeners with no medical background.
