Objectives

Narrative objectives1

The ability to localize sound sources under conditions of attentional interference, shortened stimulus duration, and reduced sound pressure levels was explored in normal hearing subjects and patients with listening difficulties, and a clinical test method for sound source localization in patients with listening difficulties was developed in order to provide basic data for the establishment of a clinical test method for sound source localization ability in patients with h

(#Listening difficulties are known to be caused by a history of childhood ear diseases, neurodevelopmental disorders, depression and other psychiatric disorders.
(Since it is known that patients with #Listening difficulties also have a history of childhood ear disorders, neurodevelopmental disorders, and psychiatric disorders such as depression, we did not add the conditions of a history of ear disorders or psychiatric disorders to the exclusion criteria for patients with normal hearing.)
