An objective estimate of listening effort could support the hearing aid fitting procedure. Most of the digital hearing aids have already hearing aid settings which are supposed to reduce the listening effort, but the effects of these settings on the individual's listening effort remain unclear. In this study, we propose an objective estimate of listening effort using electroencephalographic data....
A compressive sampling algorithm recovers approximately a nearly sparse vector x from a much smaller “sketch” given by the matrix vector product Φx. Different settings in the literature make different assumptions to meet strong requirements on the accuracy of the recovered signal. Some are robust to noise (that is, the signal may be far from sparse), but the matrix ¦ is only guaranteed to work on...
In the last decades, many investigations were done to examine the effects of sensorineural hearing loss on the speech perception ability. Besides testing hearing impaired persons, there is also the possibility to simulate the hearing loss. Therefore, some electrophysiological as well as speech recognition studies were performed in normal hearing subjects using techniques to model the sensorineural...
In clinical practice, an objective method to assess listening effort is still not available. The benefit of such a measure would be to reduce the listening effort in hearing impaired persons by an adequate adaption of their personal hearing aids. In foregoing studies, we have shown that the wavelet phase synchronization stability (WPSS) of auditory late responses (ALRs) could serve as a feasible measure...
The compressive sensing theory enables the analog-to-information conversion of a wideband signal directly by sampling the signal below the Nyquist rate and reconstruct the sampled signal perfectly. We developed a unique implementation of compressive sensing that is based on converting the signal to a time-encoded representation. The time encoding process converts an analog signal that has a continuous...
We have recently shown that tone evoked auditory late responses are able to proof that habituation is occurring. The sweep to sweep analysis using time scale coherence method from is used. Where clear results using tone evoked ALRs were obtained. Now it is of interest how does the results behave using chirp evoked ALRs compared to tone evoked ALRs so that basilar membrane dispersion is compensated...
Until now, an objective method to estimate listening effort with a minimum level of cooperation of the patient in order to fit hearing aids is not existent. The benefit of such a method would be to reduce the listening effort in hearing impaired persons by an adequate adaption of the hearing aids. Recently, we have shown that the wavelet phase synchronization stability (WPSS) of auditory late responses...
