Hearing instrument technology – What is important for the individual?
Hörselbron (The Hearing Bridge) is a newly started Swedish research
institute within hearing technology and audiology. The core activities
are research, method and technology development. The institute is
owned by the Swedish Association of Hard of Hearing People. The
institute is placed at the Department of Speech, Music, and Hearing,
Royal Institute of Technology, Sweden.
This work presented from the Hörselbron is divided into two parts. The
first part will cover and discuss limitations and possibilities
available in a hearing instrument. The second part will cover results
from the Swedish national quality register within hearing
Part i: The signal-to-noise ratio (SNR) determines the possibilities
to understand speech in noise. Several options are available to the
user in order to improve the SNR, and the hearing aids available on
the market offer different solutions. However, many of the solutions
are more or less independent of the chosen hearing aid model. This is
essential to understand when selecting a hearing aid: what is
important for the individual. Making sound audible is easy but
improving communication is difficult. Different ways to improve
communication in noisy environments and how the methods are related
with the hearing instrument will be discussed.
Part ii: The second part covers results from the Swedish national
quality register within hearing rehabilitation. The investigation
covers about 25000 prescriptions and collects information about e.g.
self-reported outcomes, hearing aid models, and audiogram. Methods and
results from the register will be discussed and presented.
