Primary outcome
stationairy and non-stationairy background noise, and compression
Secondary outcome
n.v.t.
Background summary
The speech intelligibility in normal hearing and hearing impaired listeners is
to be tested in quiet, stationary noise, and non-stationary noise with and
without advanced signal processing algorithms. Recent studies have shown that
signal processing algorithms such as compression can improve the speech
intelligibility in normal hearing listeners in non-stationary background noise.
To what extent this is applicable for listeners with a hearing impairment is
unknown.
Study objective
The study objected to tree hypotheses which had to be evaluated: speech
intelligibility is dependent of type of background noise, speech
intelligibility is dependent of the noise level, and compression can improve
the speech intelligibility in normal and hearing impaired listeners in
non-stationary background noise.
Study design
The speech intelligibility is measured in stationairy and non/stationairy
background noise with and without advanced signal processing algorithms.
