Conversation in small groups: Speaking and listening strategies depend on the complexities of the environment and group (2020)
Journal Article

Many conversations in our day-to-day lives are held in noisy environments, impeding comprehension, and in groups, taxing auditory attention-switching processes. These situations are particularly challenging for older adults in cognitive and sensory d...

On the interaction of head and gaze control with acoustic beam width of a simulated beamformer in a two-talker scenario (2019)
Journal Article

Superdirectional acoustic beamforming technology provides a high signal-to-noise ratio, but potential speech intelligibility benefits to hearing aid users are limited by the way the users move their heads. Steering the beamformer using eye gaze inste... Read More about On the interaction of head and gaze control with acoustic beam width of a simulated beamformer in a two-talker scenario.

The pupil dilation response during speech perception in dark and light: the involvement of the parasympathetic nervous system in listening effort (2018)
Journal Article

Recently, the measurement of the pupil dilation response has been applied in many studies to assess listening effort. Meanwhile, the mechanisms underlying this response are still largely unknown. We present the results of a method that separates the...

Pupil light reflex evoked by light-emitting diode and computer screen: methodology and association with need for recovery in daily life (2018)
Journal Article

Objectives: Pupil light reflex (PLR) has been widely used as a method for evaluating parasympathetic activity. The first aim of the present study is to develop a PLR measurement using a computer screen set-up and compare its results with the PLR gene...

Impact of SNR, masker type and noise reduction processing on sentence recognition performance and listening effort as indicated by the pupil dilation response (2018)
Journal Article

Recent studies have shown that activating the noise reduction scheme in hearing aids results in a smaller peak pupil dilation (PPD), indicating reduced listening effort, at 50% and 95% correct sentence recognition with a 4-talker masker. The objectiv... Read More about Impact of SNR, masker type and noise reduction processing on sentence recognition performance and listening effort as indicated by the pupil dilation response.

Predictors of entering a hearing aid evaluation period: a prospective study in older hearing-help seekers (2017)
Journal Article

This study aimed to determine the predictors of entering a hearing aid evaluation period (HAEP) using a prospective design drawing on the health belief model and the transtheoretical model. In total, 377 older persons who presented with hearing probl... Read More about Predictors of entering a hearing aid evaluation period: a prospective study in older hearing-help seekers.

Relations between self-reported daily-life fatigue, hearing status and pupil dilation during a speech perception in noise task (2017)
Journal Article

Objective: people with hearing impairment are likely to experience higher levels of fatigue due to effortful listening in daily communication. This hearing-related fatigue might not only constrain their work performance, but also result in withdrawal... Read More about Relations between self-reported daily-life fatigue, hearing status and pupil dilation during a speech perception in noise task.

Impact of stimulus-related factors and hearing impairment on listening effort as indicated by pupil dilation (2017)
Journal Article

Previous research has reported effects of masker type and signal-to-noise ratio (SNR) on listening effort, as indicated by the peak pupil dilation (PPD) relative to baseline during speech recognition. At about 50% correct sentence recognition perform... Read More about Impact of stimulus-related factors and hearing impairment on listening effort as indicated by pupil dilation.

Theoretical issues of validity in the measurement of aided speech reception threshold in noise for comparing nonlinear hearing aid systems (2016)
Journal Article

Background: Adaptive Speech Reception Threshold in noise (SRTn) measurements are often used to make comparisons between alternative hearing aid (HA) systems. Such measurements usually do not constrain the signal-to-noise ratio (SNR) at which testing...
