Brief summary

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.

Detailed description

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.

Interventions

DEVICEhearing aid with directionality

Hearing directionality allows users the ability to focus on voices and other signals of interest, reducing background noises that are unimportant.

Design outcomes

Primary

MeasureTime frameDescription
Hearing loss assessed by the SSQ 12 hearing related questionnaire2 weeksSpeech Spatial and Qualities of hearing questionnaire is designed to measure of range of hearing disabilities across several domains. Specific attention is given to hearing speech in a host of competing contexts, and to the directional, distance and movement components of spatial hearing.

Secondary

MeasureTime frameDescription
Hearing loss assessed by the AZ Bio sentence test in the presence of noise2 weeksAZ Bio sentence in noise test comprised of 15 lists of 20 sentences each and is a measure of speech perception ability by individuals that mimics real life conditions with the presence of background noise.

Other

MeasureTime frameDescription
Hearing loss will be assessed by using ecological momentary assessments to get a repeated sampling of their behaviors and experiences in real time.1 weekEcological momentary assessment will act as a digital diary, in real time, to understand subject's real life behaviors in their momentary environments.
