There is very little evidence related to a hearing aid user's ability to assemble and use a fully self-fitted hearing aid without the supervision of a clinician, or the outcomes with self-fitting or trainable hearing aids.
For adults with symmetrical, up to severe hearing loss, in-situ measures (i.e., threshold data using the hearing aid) do not differ significantly in test-retest reliability than those obtained using conventional audiometry (Level 2 Evidence).
