Paper discusses considerations in using open-fitting hearing aids, and focuses on how the Senso Diva Élan hearing aid is designed to bypass many limitations found in open-fittings. Seven limitations found in open fittings are discussed: (1) reduction of hearing aid low-frequency output, (2) increased contribution of direct sounds, (3) perceptual consequences of direct low frequency sounds, (4) “dips” and “peaks” in real-ear response, (5) reduction of the effectiveness of signal processing, (6) reduction of available gain before feedback, and (7) reduced audibility at low input levels. The authors discuss how the Senso Diva Élan hearing aid can be used to reduce these limitations, as the hearing aid was designed specifically to use an open-fitting concept for adults with high-frequency hearing loss.
