“…Within a run, the masker level was varied to determine the masking threshold for the probe. Between runs, the masker frequency was changed randomly across the following values, 0.5, 0.7, 0.9, 1, 1.1, 1.2, 1.3 and 1.6 times the probe frequency and resulted in an iso-forward masking contour (IFMC; Meddis et al, 2010;Lecluyse et al, 2013;Tan et al, 2013). IFMCs were generated for probe frequencies 0.25, 0.5, 1, 2, 4, and 6 kHz.…”

This study investigated the potential and limitations of a self-fit hearing aid. This can be used in the “developing” world or in countries with large distances between the hearing-impaired subjects and the professional. It contains an on-board tone generator for in situ user-controlled, automated audiometry, and other tests for hearing aid fitting. Twenty subjects with mild hearing losses were involved. In situ audiometry showed a test-retest reliability (SD <3.7 dB) that compared well with the precision of diagnostic audiometry using headphones. There was good correspondence (SD <5.2 dB) with traditional pure-tone audiometry. In situ loudness scaling yielded important information about suprathreshold perception, which will have an added value for the selection of compression and the selection of maximum power output to be allowed in hearing aids.

“…Audiometric testing was performed in a double-walled, sound-attenuated booth at the University Hospital of Zurich. Pure-tone thresholds were measured for 500, 1000, 2000 and 4000 Hz using a probe-detection paradigm in which pure tones were presented for 250 ms (Lecluyse et al, 2013;Lecluyse and Meddis, 2009). Tones were delivered via a custom-written Matlab software to circumaural headphones (Sennheiser HD 280-13 300 Ω…”

Interacting effects of frontal lobe neuroanatomy and working memory capacity to older listeners’ speech recognition in noise

Many older adults are struggling with understanding spoken language, particularly when background noise is present interferes with comprehension. In the present study, we investigated a potential interaction between two well-known factors associated with greater speech-in-noise (SiN) reception thresholds in older adults, namely a) lower working memory capacity and b) age-related structural decline of frontal lobe regions. In a sample of older adults (N=25) and younger controls (N=13) with normal pure-tone thresholds, SiN reception thresholds and working memory capacity were assessed. Furthermore, T1-weighted structural MR-images were recorded to analyze neuroanatomical traits (i.e., cortical thickness (CT) and cortical surface area (CSA)) of the cortex. As expected, the older group showed greater SiN reception thresholds compared to the younger group. We also found consistent age-related atrophy (i.e., lower CT) in brain regions associated with SiN recognition namely the superior temporal lobe bilaterally, the right inferior frontal and precentral gyrus, as well as the left superior frontal gyrus. Those older participants with greater atrophy in these brain regions also showed greater SiN reception thresholds. Interestingly, the association between CT in the left superior frontal gyrus and SiN reception thresholds was moderated by individual working memory capacity. Older adults with greater working memory capacity benefitted more strongly from thicker frontal lobe regions when it comes to improve SiN recognition. Overall, our results fit well into the literature showing that age-related structural decline in auditory- and cognition-related brain areas is associated with greater SiN reception thresholds in older adults. However, we highlight that this association changes as a function of individual working memory capacity. We therefore believe that future interventions to improve SiN recognition in older adults should take into account the role of the frontal lobe as well as individual working memory capacity.

Acquisition of auditory profiles for good and impaired hearing

Abstract: The hearing profiles are informative with respect to supra-threshold hearing performance and the information is easily accessible through the graphical display. Further development is required for routine use in a clinical context.
