ABSTRACT
One of the common complaints from persons with hearing aids is occlusion effect (OE). OE is mainly caused by the enhancement of low-frequency components of a sound and this problematic occlusion could be reduced through decreasing low-frequency gains or modifying the size/length of the vent. Since vents are not always with uniform lengths or diameters, audiologists need to understand various interrelated factors such as vent sizes and hearing aid gains based on patterns of hearing loss. This article reports the cases where OE problems were managed through modified vents with simple self-questionnaires.
Key Words: Occlusion effect·Vent·Hearing aid modification.
중심단어: 폐쇄효과· 환기구· 보청기구조변경.
