Background summary
Hearing impairments can have different causes and are different for all
patients with hearing complaints. Different expressions of hearing impairment
have different effects on the daily life of the patients. However, one of the
main complaints is not being able to understand speech under adverse
conditions, which impedes communication. For improved communication, a
noise-suppression scheme was developed that improves speech reception in noise
by 1 to 2 dB, depending on conditions. The current project focuses on
implementing this scheme under the technical limitations of present-day hearing
assistants.
Study objective
The aim of the study is to establish the effectiveness of the developed LINE-1
noise suppression scheme for settings that are realistic under the technical
possibilities of hearing aids and cochlear implants (CIs). The present study is
a valorisation study in the sense that the outcomes, when positive, will be
used to interest the manufacturers of hearing aids and CIs in applying the
present technology in their commercial devices.
Study design
Hearing study using processed and unprocessed speech-in-noise stimuli. The
auditory stimuli are presented via head phones to normally-hearing and
hearing-impaired listeners and via speakers or the auxiliary input for CI
wearers.
Study burden and risks
The burden of the participants comprises of either repeating perceived speech
or of pressing a key on a keyboard in response to the speech. A complete
measurement session will take approximately one hour and thirty minutes to two
hours (with brakes). The sound presentation levels used will all be in the
comfortable range of the listeners. If any listeners happen to find any sound
presentations too loud, those presentations will be reduced in level to a level
that is comfortable for them. The proposed type of research is extremely low
risk.
