The influence of age and hearing loss on thresholds measured using the TFS-AF test.

Objective: The upper limit of sensitivity to binaural temporal fine structure (TFS) is around 1400 Hz. Higher values have been reported when keeping interaural phase differences fixed and varying the frequency adaptively, as in the adaptive-frequency TFS test [TFS-AF, Füllgrabe et al., Int J Audiol, 56, 926-935].

The impact of face coverings on audio-visual contributions to communication with conversational speech.

The use of face coverings can make communication more difficult by removing access to visual cues as well as affecting the physical transmission of speech sounds. This study aimed to assess the independent and combined contributions of visual and auditory cues to impaired communication when using face coverings. In an online task, 150 participants rated videos of natural conversation along three dimensions: (1) how much they could follow, (2) how much effort was required, and (3) the clarity of the speech.

Feasibility of Diagnosing Dead Regions Using Auditory Steady-State Responses to an Exponentially Amplitude Modulated Tone in Threshold Equalizing Notched Noise, Assessed Using Normal-Hearing Participants.

The aim of this study was to assess feasibility of using electrophysiological auditory steady-state response (ASSR) masking for detecting dead regions (DRs). Fifteen normally hearing adults were tested using behavioral and electrophysiological tasks. In the electrophysiological task, ASSRs were recorded to a 2 kHz exponentially amplitude-modulated tone (AM2) presented within a notched threshold equalizing noise (TEN) whose center frequency (CF) varied.

Preferred music-listening level in musicians and non-musicians.

The purpose of this study was to establish whether preferred music-listening level differed between musicians and non-musicians, and whether preferred music-listening level was related to music genre preference and lifetime noise exposure. Seventeen musicians (mean age = 29.06 years, SD = 4.

Improving the measurement and acoustic performance of transparent face masks and shields.

Opaque face masks harm communication by preventing speech-reading (lip-reading) and attenuating high-frequency sound. Although transparent masks and shields (visors) with clear plastic inserts allow speech-reading, they usually create more sound attenuation than opaque masks. Consequently, an iterative process was undertaken to create a better design, and the instructions to make it are published.

Threshold Equalizing Noise Test Reveals Suprathreshold Loss of Hearing Function, Even in the "Normal" Audiogram Range.

Objectives: The threshold equalizing noise (TEN(HL)) is a clinically administered test to detect cochlear "dead regions" (i.e., regions of loss of inner hair cell [IHC] connectivity), using a "pass/fail" criterion based on the degree of elevation of a masked threshold in a tone-detection task.

On prediction of aided behavioural measures using speech auditory brainstem responses and decision trees.

Current clinical strategies to assess benefits from hearing aids (HAs) are based on self-reported questionnaires and speech-in-noise (SIN) tests; which require behavioural cooperation. Instead, objective measures based on Auditory Brainstem Responses (ABRs) to speech stimuli would not require the individuals' cooperation. Here, we re-analysed an existing dataset to predict behavioural measures with speech-ABRs using regression trees.

Low-sound-level auditory processing in noise-exposed adults.

Early signs of noise-induced hearing damage are difficult to identify, as they are often confounded by factors such as age, audiometric thresholds, or even music experience. Much previous research has focused on deficits observed at high intensity levels. In contrast, the present study was designed to test the hypothesis that noise exposure causes a degradation in low-sound-level auditory processing in humans, as a consequence of dysfunction of the inner hair cell pathway.

Associations between pre-stimulus alpha power, hearing level and performance in a digits-in-noise task.

Objective: Baseline electroencephalography (EEG) alpha power, i.e. that measured prior to stimulus presentation, is a potential objective predictor of task performance.

Speech-ABRs in cochlear implant recipients: feasibility study.

The aim of this study was to assess the feasibility of recording speech-ABRs from cochlear implant (CI) recipients, and to remove the artefact using a clinically applicable single-channel approach. Speech-ABRs were recorded to a 40 ms [da] presented loudspeaker using a two-channel electrode montage. Additionally, artefacts were recorded using an artificial-head incorporating a MED-EL CI with stimulation parameters as similar as possible to those of three MED-EL participants.

Relation between serum amyloid A truncated peptides and their suprastructure chirality.

Amyloids are pathological fibrillar aggregates of proteins related to over 20 diseases. Amyloid fibers are characterized by the cross-beta motif, which is minimally defined as a series of beta-strands extended perpendicular to the fiber axis, joined by hydrogen bonds parallel to the fiber direction. Several structures, all in agreement with the cross-beta definition, have been proposed for specific amyloids.

Chirality of amyloid suprastructures.

Amyloids are pathological fibrillar aggregates of proteins related to more than 20 different diseases. Amyloid fibers have a characteristic cross-beta structure consisting of a series of beta-strands extended perpendicular to the fiber axis and joined by hydrogen bonds parallel to the fiber direction. Fibril aggregation results in helical suprastructures.
