Outcome measures
Primary outcome
This study aims to validate the ESTI model using speech intelligibility
measurements. We aim to do speech intelligibility measurements for all subjects
in different conditions (noise type en reverberation time) and compare these to
the model outcomes.
Secondary outcome
NA
Background summary
People often have problems with speech understanding in noise, especially when
they suffer from hearing impairment. This project aims to estimate the speech
intelligibility in fluctuating noise and reverberant environments in order to
advise in assistive listening devices, hearing aids and/or acoustical
adjustments
Study objective
To validate the Extended Speech Transmission Index (ESTI) model for fluctuating
noise in reverberant conditions in both normal hearing and hearing impaired
subjects
Study design
An observational feasibility study.
Study burden and risks
Since this study is observational, the burden for the subject is minimal. The
tests, which are similar to those done in clinical practice, will be done
during a one time visit. The experiments can potentially lead to a much broader
application of the Speech Transmission Index (STI). This will give
professionals a better tool to quantify problems which people experience in the
working or classroom environment.
