Patients with a precipitous high-frequency hearing loss pose a unique challenge for dispensing audiologists. Hearing aids rarely provide sufficient high-frequency gain without over-amplifying the lower frequencies, which results in poor sound quality or significant sound distortions. The occlusion effect and upward spread of masking may also occur. For these patients, the high frequencies are not easily reachable. Recently it has been suggested that a precipitous loss may make the high
