Muddy, muddled, or muffled? Understanding the perception of audio quality in music by hearing aid users (2024)
Journal Article

Introduction: Previous work on audio quality evaluation has demonstrated a developing convergence of the key perceptual attributes underlying judgments of quality, such as timbral, spatial and technical attributes. However, across existing research t... Read More about Muddy, muddled, or muffled? Understanding the perception of audio quality in music by hearing aid users.

The effect of stimulus duration on preferences for gain adjustments when listening to speech (2021)
Journal Article

Objectives: In the personalisation of hearing-aid fittings, gain is often adjusted to suit patient preferences using live speech. When using brief sentences as stimuli, the minimum gain adjustments necessary to elicit consistent preferences (“prefere...

Clinical Trials and Outcome Measures in Adults With Hearing Loss (2021)
Journal Article

Clinical trials are designed to evaluate interventions that prevent, diagnose or treat a health condition and provide the evidence base for improving practice in health care. Many health professionals, including those working within or allied to hear... Read More about Clinical Trials and Outcome Measures in Adults With Hearing Loss.

Changes in Orientation Behavior due to Extended High-Frequency (5 to 10 kHz) Spatial Cues (2021)
Journal Article

Objectives: Current hearing aids have a limited bandwidth, which limits the intelligibility and quality of their output, and inhibits their uptake. Recent advances in signal processing, as well as novel methods of transduction, allow for a greater...

Audiometric profiles and patterns of benefit: a data-driven analysis of subjective hearing difficulties and handicaps (2021)
Journal Article

Objective: Hearing rehabilitation attempts to compensate for auditory dysfunction, reduce hearing difficulties and minimize participation restrictions that can lead to social isolation. However, there is no systematic approach to assess the quality o...

The perceptual limitations of troubleshooting hearing-aids based on patients’ descriptions (2020)
Journal Article

Objectives: Hearing-aid frequency-gain responses are routinely adjusted by clinicians to patient preferences and descriptions. This study measured the minimum gain adjustments required to elicit preferences, and the assignment of descriptors to gain...

Exploring the Factor Structure of the Glasgow Children’s Benefit Inventory: New Recommendations for Reporting Results (2020)
Journal Article

Objective Patient-reported outcomes can be useful for reporting benefit from non-life-saving interventions, but often they report a single overall score, which means that much information on the specific areas of benefit is lost. Our aim was to per... Read More about Exploring the Factor Structure of the Glasgow Children’s Benefit Inventory: New Recommendations for Reporting Results.

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...

An Exploratory Study of EEG Alpha Oscillation and Pupil Dilation in Hearing-Aid Users During Effortful listening to Continuous Speech (2020)
Journal Article

Individuals with hearing loss allocate cognitive resources to comprehend noisy speech in everyday life scenarios. Such a scenario could be when they are exposed to ongoing speech and need to sustain their attention for a rather long period of time, w... Read More about An Exploratory Study of EEG Alpha Oscillation and Pupil Dilation in Hearing-Aid Users During Effortful listening to Continuous Speech.

Speech, movement and gaze behaviours during dyadic conversation in noise (2019)
Journal Article

How do people have conversations in noise and make themselves understood? While many previous studies have investigated speaking and listening in isolation, this study focuses on the behaviour of pairs of individuals in an ecologically valid context....

Discrimination of Gain Increments in Speech (2019)
Journal Article

© The Author(s) 2019. During a hearing-aid fitting, the gain applied across frequencies is often adjusted from an initial prescription in order to meet individual needs and preferences. These gain adjustments in one or more frequency bands are common... Read More about Discrimination of Gain Increments in Speech.

Discrimination of gain increments in speech-shaped noises (2019)
Journal Article

Frequency-dependent gain adjustments are routine in hearing-aid fittings, whether in matching to real-ear targets or fine-tuning to patient feedback. Patient feedback may be unreliable and fittings inefficient if adjustments are not discriminable. To... Read More about Discrimination of gain increments in speech-shaped noises.

A low-frequency dual-band operational microphone mimicking the hearing property of Ormia Ochracea (2018)
Journal Article

This paper introduces a directional MEMS microphone designed for hearing aid applications appropriate to low-frequency hearing impairment, inspired by the hearing mechanism of a fly, the female Ormia ochracea. It uses both piezoelectric and capacitiv... Read More about A low-frequency dual-band operational microphone mimicking the hearing property of Ormia Ochracea.

A MEMS microphone inspired by Ormia for spatial sound detection (2018)
Conference Proceeding

This work introduces a MEMS microphone with two pairs of orthogonal and joined sensor membranes, with independent acoustic directionality responses, leading to a 3D sound localization potential. This single microphone can thus be regarded as two indi... Read More about A MEMS microphone inspired by Ormia for spatial sound detection.

Influence of microphone housing on the directional response of piezoelectric MEMS microphones inspired by Ormia ochracea (2017)
Journal Article

The influence of custom microphone housings on the acoustic directionality and frequency response of a multi-band bio-inspired MEMS microphone is presented. The 3.2mm by 1.7mm piezoelectric MEMS microphone, fabricated by a cost-effective multi-user p...
