| description | <p dir="ltr"><b>Purpose: </b>The use of traditional (i.e., unmodified) listening scopes for hearing aid and assistive listening device checks is not practically accessible for all clinicians; such is the case for deaf audiologists. Despite the need, there is a paucity of evidence-based information regarding modified listening scopes. The focus of this investigation was to evaluate the output clarity through various modified listening scopes via a measure of distortion. The impact of hearing aid type on measurements was also preliminarily analyzed.</p><p dir="ltr"><b>Method: </b>Eight test hearing aids were measured under seven listening scope conditions. A distortion analysis was performed for each setup across 13 frequencies from 250 through 4000 Hz on the Verifit2.
