Spatial hearing loss
open-in-new
<p>Spatial hearing loss refers to a form of <a href="/facts/Deafness/PT2xcLaX">deafness</a> that is an inability to use spatial cues about where a sound originates from in space. Poor <a href="/facts/Sound_localization/PQTFmt1w">sound localization</a> in turn affects the ability to understand speech in the presence of background noise. </p><p>People with spatial hearing loss have difficulty processing speech that arrives from one direction while simultaneously filtering out 'noise' arriving from other directions. Research has shown spatial hearing loss to be a leading cause of central auditory processing disorder (CAPD) in children. Children with spatial hearing loss commonly present with difficulties understanding speech in the classroom. Spatial hearing loss is found in most people over 70 years of age, and can sometimes be independent of other types of age related hearing loss. As with <a href="/facts/Presbycusis/Lg7eI1xU">presbycusis</a>, spatial hearing loss varies with age. Through childhood and into adulthood it can be viewed as spatial hearing gain (with it becoming easier to hear speech in noise), and then with middle age and beyond the spatial hearing loss begins (with it becoming harder again to hear speech in noise). </p>
