OBJECTIVE: To compare recordings of bone conduction (BC) stimulated auditory brainstem response (ABR) obtained using the newer BC transducer Radioear B81 and the conventional BC transducer Radioear B71. Balanced electromagnetic separation transducer (BEST) design found in the B81 may influence the ABR magnitudes and latencies, as well as electrical artefacts. DESIGN: ABRs to tone burst stimuli of 500 Hz, 2000 Hz, 4000 Hz, click stimulation, and broad-band chirp stimulation at 20 and 50 dB nHL were recorded...

OBJECTIVE: To examine the relationship between extended high-frequency pure tone hearing thresholds (frequencies 10 to 14 kHz) and working memory capacity (WMC), inhibitory control, and cognitive flexibility. DESIGN: Experimental study measuring correlations between different high-frequency hearing threshold measures and cognitive measures. STUDY: Pure tone audiometry was assessed in the extended high-frequency (frequencies 10, 12.5 and 14 kHz)...

OBJECTIVE: This study evaluates the Danish test battery for auditory processing disorder (APD). The battery consists of four behavioural tests, two speech and two non-speech stimuli tests. The evaluation includes determination of: (1) new cut-off values (pass-fail criteria), (2) the sensitivity and the specificity of the entire test battery and (3) the failure rate of different test combinations. DESIGN: For each test in the battery, cut-off values were determined using the weighted Youden index...

OBJECTIVE: To determine the training, self-reported competence and practice patterns of South African audiologists (SAAs) regarding cerumen management (CM). DESIGN: Prospective cross-sectional survey. An online questionnaire was completed by SAA between July and September 2016. The questionnaire addressed sections on educational training, experience and practice patterns of SAAs regarding CM.

OBJECTIVE: To evaluate the feasibility of predictable or unpredictable amplitude-modulated sounds for tinnitus therapy. DESIGN: The study consisted of two parts. (1) An adaptation experiment. Loudness level matches and rating scales (10-point) for loudness and distress were obtained at a silent baseline and at the end of three counterbalanced 30-min exposures (silence, predictable and unpredictable). (2) A qualitative 2-week sound therapy feasibility trial. Participants took home a personal music player (PMP)...

OBJECTIVE: This study was designed to test whether cue utilisation might be employed as a tool to assess the diagnostic skills of audiologists. The utilisation of cues is a characteristic of expertise and critical for successful diagnoses in clinical settings. However, neither in training nor in practice, is there a means by which the diagnostic skills of audiologists can be assessed objectively and reliably. DESIGN: The study comprised a pre-post training evaluation, controlling for prior exposure to the diagnostic testing tool...

OBJECTIVE: To examine benefit from immediate repetition of a masked speech message in younger, middle-aged and older adults. DESIGN: Participants listened to sentences in conditions where only the target message was repeated, and when both the target message and its accompanying masker (noise or speech) were repeated. In a follow-up experiment, the effect of repetition was evaluated using a square-wave modulated noise masker to compare benefit when listeners were exposed to the same glimpses of the target message during first and second presentation versus when the glimpses differed...

OBJECTIVE: The objective was to evaluate and select appropriate parameters for a multi-channel transient reduction (MCTR) algorithm for detecting and attenuating transient sounds in speech. DESIGN: In each trial, the same sentence was played twice. A transient sound was presented in both sentences, but its level varied across the two depending on whether or not it had been processed by the MCTR and on the "strength" of the processing. The participant indicated their preference for which one was better and by how much in terms of the balance between the annoyance produced by the transient and the audibility of the transient (they were told that the transient should still be audible)...

OBJECTIVE: The frequency-following response (FFR) is a neurophonic potential used to assess auditory neural encoding at subcortical stages. Despite the FFR's empirical and clinical utility, basic response properties of this evoked potential remain undefined. DESIGN: We measured FFRs to speech and nonspeech (pure tone, chirp sweeps) stimuli to quantify three key properties of this potential: level-dependence (I/O functions), adaptation and the upper limit of neural phase-locking...

OBJECTIVE: The objective of this study is to quantify the effect of the Bone Conduction Implant (BCI) on sound localisation accuracy in subjects with conductive hearing loss (CHL). DESIGN: The subjects were tested in a horizontal sound localisation task in which localisation responses were objectively obtained by eye-tracking, in a prospective, cross-sectional design. The tests were performed unaided and unilaterally aided. The stimulus used had a spectrum similar to female speech and was presented at 63 and 73 dB SPL...

OBJECTIVE: To develop a decision aid for tinnitus care that would meet international consensus for decision aid quality. DESIGN: A mixed methods design that included qualitative in-depth interviews, literature review, focus groups, user testing and readability checking. STUDY SAMPLE: Patients and clinicians who have clinical experience of tinnitus. RESULTS: A decision aid for tinnitus care was developed. This incorporates key evidence of efficacy for the most frequently used tinnitus care options, together with information derived from patient priorities when deciding which choice to make...

OBJECTIVE: The purpose of this article is to discuss the most commonly prescribed vestibulotoxic medications and their impact on the vestibular system, to describe the clinical features of vestibular ototoxicity including symptoms reported by patients, and to describe assessment tools that may be used in a monitoring programme, including the functional impact of vestibular loss. Recently published data from a cohort of patients exposed to systemic aminoglycosides (AGS) are summarised, which highlight the importance of monitoring...

DESIGN: RLO content was based on an electronically-delivered Delphi review, workshops, and iterative peer-review and feedback using a mixed-methods participatory approach. STUDY SAMPLE: An expert panel of 33 hearing healthcare professionals, and workshops involving 32 hearing aid users and 11 audiologists...

OBJECTIVE: To create a hearing test useable without the involvement of a clinician or calibrated equipment, suitable for children aged 5 or older. DESIGN: The tablet-based app (Sound Scouts) includes tests of speech in quiet, speech in noise and tones in noise, all embedded in game designed to maintain attention. Data were collected to intelligibility-equalize the stimuli, establish normative performance, and evaluate the sensitivity with which Sound Scouts detected known hearing problems and identified their type...

OBJECTIVE: Research has minimally focussed on the music listening habits and preferred sound volumes among adolescents with severe to profound congenital HL. Listening to music played at loud sound volumes and for a long duration of time could imply risks of worsening the HL. Therefore, it is important to investigate the listening habits in adolescents with HL. The aim of the present study was to describe the use of personal music devices, subjective estimated sound levels, measured sound levels, listening habits, and hearing symptoms in adolescents with severe to profound hearing loss compared with adolescents with normal hearing...

OBJECTIVE: To assess the prevalence of hyperacusis and severe hyperacusis among children and adolescents seen at an audiology outpatient tinnitus and hyperacusis service. DESIGN: This was a retrospective study. Hyperacusis was considered as present if the average uncomfortable loudness level (ULL) at 0.25, 0.5, 1, 2, 4 and 8 kHz for the ear with the lower average ULL, which is denoted as ULLmin, was ≤77 dB HL. Severe hyperacusis was considered as present if the ULL was 30 dB HL or less for at least one of the measured frequencies for at least one ear...
