OBJECTIVE: The purpose of this study was to assess audiologists' perceptions of ethics and moral climate in the workplace. DESIGN: The Ethics Environmental Questionnaire (EEQ) was sent out to all audiologists registered with the professional body Audiology Australia. Participants were also invited to undertake a semi-structured interview. STUDY SAMPLE: A total of 301 audiologists completed the questionnaire. Eight of these participants also agreed to complete the interview...

OBJECTIVE: A previous study [Rawool, V. W. (2016). Auditory processing deficits: Assessment and intervention. New York, NY: Thieme Medical Publishers, Inc., pp. 186-187] demonstrated objective assessment of binaural summation through right contralateral acoustic reflex thresholds (ARTs) in women. The current project examined if previous findings could be generalised to men and to the left ear. DESIGN: Cross-sectional. STUDY SAMPLE: Sixty individuals participated in the study...

OBJECTIVE: We investigated whether speech intelligibility and listening effort for hearing-aid users is affected by semantic context and hearing-aid setting. DESIGN: Participants heard target sentences spoken in a reverberant background of cafeteria noise and competing speech. Participants reported each sentence verbally. Eight participants also rated listening effort after each sentence. Sentence topic was either the same as, or different from, the previous target sentence...

OBJECTIVE: This study aims to investigate the prevalence of hearing loss, and to analyse the major demographics and risk factors that influence the prevalence in older adults of China. DESIGN: Cross-sectional investigation. STUDY SAMPLE: Probability proportionate to size sampling (PPS) was adopted for this survey. Among 45,052 individuals, 6984 older adults (≥60 years) were selected as subjects for this study. RESULTS: The prevalence of hearing loss defined as a speech frequency pure tone average of more than 25 dB HL in the better ear was 58...

OBJECTIVE: To consider the evolving concept of auditory processing disorder (APD). DESIGN: Narrative review and opinion piece. STUDY SAMPLE: Eight approaches to APD described in the literature and its definitions by ten societies or groups from around the world. RESULTS: The dominant conceptualisation of APD remains one of disorders (or at least deficits) in the bottom-up processing of sound in the primary auditory nervous system that are not due to higher order (top-down) language or cognitive deficits...

OBJECTIVE: A psychoacoustic procedure designed for the precise assessment of perceptional threshold (T-level) in cochlear implant (CI) users is presented. The impact of this procedure on speech perception was investigated. DESIGN: Individual T-level measurements were obtained with the proposed procedure and three different speech processor fitting conditions were applied: (1) fitting familiar to the subject, T-levels unchanged, (2) T-level set to thresholds determined with the new procedure, (3) T-level set to thresholds determined with the new procedure, but T-level is decreased by 10 clinical units (CU)...

OBJECTIVE: The aim of this study is to investigate whether the Big Five personality traits predict the outcome of Internet-based cognitive behavioural therapy (ICBT) and whether they moderate the outcome between ICBT and face-to-face group cognitive behavioural therapy (GCBT). DESIGN: This study investigated the Big Five personality traits as predictors and moderators of the outcome (tinnitus handicap) in a trial comparing ICBT and GCBT for chronic tinnitus. STUDY SAMPLE: N = 84 patients with chronic tinnitus were randomised to either ICBT (n = 41) or GCBT (n = 43)...

This Cochrane corner features the review entitled "Hearing aids for mild to moderate hearing loss in adults" published in 2017. In their review, Ferguson et al. identified five randomised controlled trials (RCTs) involving 825 participants, with moderate quality of evidence shown for all domains except adverse effects. Results showed a large beneficial effect of hearing aids on hearing-specific health-related quality of life and listening ability, and a small yet significant beneficial effect on overall health-related quality of life...

OBJECTIVE: The purpose of this study was to evaluate the reliability and validity of four subjective questions related to listening effort. A secondary purpose of this study was to evaluate the effects of hearing aid beamforming microphone arrays on word recognition and listening effort. DESIGN: Participants answered subjective questions immediately following testing in a dual-task paradigm with three microphone settings in a moderately reverberant laboratory environment in two noise configurations...

OBJECTIVE: The effects of rate on auditory-evoked potentials (AEP) to short noise gaps (12 ms) recorded at high sampling rates using wide-band filters were investigated. DESIGN: Auditory brainstem (ABR), middle latency (MLR), late latency (LLR) and steady-state (ASSR) responses were simultaneously recorded in adult subjects at four gap rates (0.5, 1, 5 and 40 Hz). Major components (V, Na, Pa, Nb, Pb, N1 and P2) were identified at each rate and analysed for latency/amplitude characteristics...

OBJECTIVE: To determine the efficacy of deficit-specific remediation for spatial processing disorder, quantify effects of remediation on functional listening, and determine if remediation is maintained. DESIGN: Participants had SPD, diagnosed using the Listening in Spatialised Noise-Sentences test. The LiSN and Learn software was provided as auditory training. Post-training, repeat LiSN-S testing was conducted. Questionnaires pre- and post-training acted as subjective measures of remediation...

OBJECTIVE: Noise-induced hearing problems among young adults are increasing due to participation in loud activities. This study explored attitudes towards leisure noise, hearing protection, and perceived susceptibility to noise damage in young adults with no diagnosed hearing problems. Understanding attitudes and behaviours will assist with the future development of strategies to improve awareness and use of hearing protection. DESIGN: A qualitative study. STUDY SAMPLE: Four focus groups, with 28 adults aged 18-35 years (6 male; 22 female; mean age 23 years)...

OBJECTIVE: The objective of this study was to evaluate the feasibility of the Chinese (Mandarin) Tinnitus Handicap Inventory (THI-C) by comparing patient-reported and clinician-interviewed outcomes and to raise awareness of the difficulties in using adapted international test measures. DESIGN: All patients were required to first complete the THI-C independently. Then, clinicians conducted a face-to-face interview, explained the exact meaning of each item and re-evaluated every item based on the patient's descriptions...

OBJECTIVE: Binaural cues such as interaural level differences (ILDs) are used to organise auditory perception and to segregate sound sources in complex acoustical environments. In bilaterally fitted hearing aids, dynamic-range compression operating independently at each ear potentially alters these ILDs, thus distorting binaural perception and sound source segregation. DESIGN: A binaurally-linked model-based fast-acting dynamic compression algorithm designed to approximate the normal-hearing basilar membrane (BM) input-output function in hearing-impaired listeners is suggested...

OBJECTIVE: Recruiting into clinical trials on time and on target is a major challenge and yet often goes unreported. This study evaluated the adjustment to procedures, recruitment and screening methods in two multi-centre pharmaceutical randomised controlled trials (RCTs) for hearing-related problems in adults. DESIGN: Recruitment monitoring and subsequent adjustment of various study procedures (e.g. eligibility criteria, increasing recruiting sites and recruitment methods) are reported...

OBJECTIVE: This study assessed the validity of DPOAE screening conducted by village health workers (VHWs) in a rural community. Real-time click evoked tele-auditory brainstem response (tele-ABR) was used as the gold standard to establish validity. DESIGN: A cross-sectional design was utilised to compare the results of screening by VHWs to those obtained via tele-ABR. Study samples: One hundred and nineteen subjects (0 to 5 years) were selected randomly from a sample of 2880 infants and young children who received DPOAE screening by VHWs...

OBJECTIVE: To evaluate the validity and efficacy of a transient noise reduction algorithm (TNR) in cochlear implant processing and the interaction of TNR with a continuous noise reduction algorithm (CNR). DESIGN: We studied the effects of TNR and CNR on the perception of realistic sound samples with transients, using subjective ratings of annoyance, a speech-in-noise test and a noise tolerance test. STUDY SAMPLE: Participants were 16 experienced cochlear implant recipients wearing an Advanced Bionics Naida Q70 processor...
