The primary purpose of this research trial is to evaluate asymmetrical directionality in bimodal users for hearing speech in noise in the sound field and in daily life using an EMA tool. The aim is to collect information regarding hearing for speech in background noise as well as end-user insights, testimonials, and communication content.
Research supports that bimodal stimulation includes improvements in auditory performance and daily living over using a cochlear implant (CI) or hearing aid (HA) alone. Although bimodal users continue to achieve high levels of satisfaction, speech perception in noise continues to be highly problematic. The aim of this field study is to identify which directionality schemes in a bimodal solution are preferred by users using an ecological momentary assessment tool.
