OBJECTIVE: The need to develop a measure of managing children with a single profile of auditory processing disorders (APDs), and differentiate between true and artefactual improvements necessitated the study. The study also sought to determine the efficacy of interventions - both single and combined on APD, against no-treatment. DESIGN: A randomised controlled trial of interventions (RCT) was adopted. Participants were randomly allocated to each of the intervention groups or the no intervention group...

OBJECTIVE: This study obtained preliminary data using two types of sound therapy to suppress tinnitus and/or reduce its functional effects: (1) Notched noise (1000-12,000 Hz notched within a 1-octave range centred around the tinnitus pitch match [PM] frequency); and (2) Matched noise (1-octave wide band of noise centred around the PM frequency). A third (Placebo) group listened to low frequency noise (250-700 Hz). DESIGN: Participants with bothersome tinnitus were randomised into one of the three groups and instructed to listen to the acoustic stimulus for 6 hours a day for 2 weeks...

OBJECTIVES: To review literature on the use of manual and automatically switching multimemory devices by hearing aid and CI recipients, and to investigate if recipients appreciate and adequately use the ability to switch between programmes in various listening environments. DESIGN: Literature was searched using PubMed, Embase and ISI/Web of Science. Additional studies were identified by screening reference and citation lists, and by contacting experts. STUDY SAMPLE: The search yielded 1109 records that were screened on title and abstract...

OBJECTIVE: The research objective was to identify processes that could either facilitate or hinder clinical implementation of an Internet-based cognitive behavioural therapy intervention for tinnitus in the UK. This was done by exploring the research context, the intervention components and the factors that contributed to the outcomes obtained. DESIGN: This study investigated eight processes including the recruitment strategies, reach, research context, treatment dose delivered and received, implementation fidelity, barriers to implementation and effectiveness of the intervention...

OBJECTIVE: Patient-centred communication (PCC) is an essential skill for effective healthcare provision and is accepted as a core competency in medicine and allied health. In audiology, recent studies have shown that audiologists rarely display PCC in adult hearing interactions. This highlights a need to investigate how PCC is taught and learnt in audiology. There is a paucity of studies on PCC in audiology education. The aim of this study is to examine educator perceptions of teaching PCC, including barriers and facilitators, in Australian graduate audiology programmes...

OBJECTIVES: Integrating audiological management into the care pathways of clinical specialties that prescribe ototoxic medications for essential, often life-preserving medical care that is critical for early hearing loss identification and remediation. Research shows that successful implementation of a new health service or intervention requires alignment of goals among provider groups, institutional leadership and patients. Thoughtful consideration of the physician's viewpoints about ototoxicity and its implications for treatment planning is, therefore, important for the implementation and enduring success of an ototoxicity monitoring programme (OMP)...

OBJECTIVE: Loudness perception of binaural broadband signals, e.g. speech shaped noise, shows large individual differences using frequency-dependent amplification which was adjusted to restore the loudness perception of monaural narrowband signals in hearing-impaired (HI) listeners. To better understand and quantify this highly individual effect, loudness perception of broadband stimuli consisting of a number of spectrally separated narrowband components which where individually adjusted to equal loudness is of interest...

OBJECTIVE: This study examined the influence of prescription on hearing aid (HA) fitting characteristics and 5-year developmental outcomes of children. DESIGN: A randomised controlled trial implemented as part of a population-based study on Longitudinal Outcomes of Children with Hearing Impairment (LOCHI). STUDY SAMPLE: Two-hundred and thirty-two children that were fit according to either the National Acoustic Laboratories (NAL) or Desired Sensation Level (DSL) prescription...

OBJECTIVE: The current research investigated whether professional musicians outperformed non-musicians on auditory processing and speech-in-noise perception as assessed using behavioural and electrophysiological tasks. DESIGN: Spectro-temporal processing skills were assessed using a psychoacoustic test battery. Speech-in-noise perception was measured using the Listening in Spatialised Noise - Sentences (LiSN-S) test and Cortical Auditory Evoked Potentials (CAEPs) recorded to the speech syllable/da/presented in quiet and in 8-talker babble noise at 0, 5, and 10 dB signal-to-noise ratios (SNRs)...

OBJECTIVE: The aims were to 1) establish which of the four algorithms for estimating residual noise level and signal-to-noise ratio (SNR) in auditory brainstem responses (ABRs) perform better in terms of post-average wave-V peak latency and amplitude errors and 2) determine whether SNR or noise floor is a better stop criterion where the outcome measure is peak latency or amplitude. DESIGN: The performance of the algorithms was evaluated by numerical simulations using an ABR template combined with electroencephalographic (EEG) recordings obtained without sound stimulus...

OBJECTIVES: This study describes older adults' experiences with a new hearing aid (HA) during the first 6 months after fitting. DESIGN: In a longitudinally designed study, experiences and issues with HA use were assessed at a six-month follow-up appointment in individual structured interviews lasting 30 min. Associations between HA experiences and demographic factors, degree of hearing loss, and an objective measure of HA use (datalogging) were also examined. STUDY SAMPLE: 181 HA recipients (≥60 years) attending a six-month follow-up appointment...

OBJECTIVE: This technical paper describes a biologically inspired hearing aid algorithm based on a computer model of the peripheral auditory system simulating basilar membrane compression, reflexive efferent feedback and its resulting properties. DESIGN: Two evaluations were conducted on the core part of the algorithm, which is an instantaneous compression sandwiched between the attenuation and envelope extraction processes of a relatively slow feedback compressor...

OBJECTIVE: To evaluate a Dutch online speech-in-noise screening test (in Dutch: "Kinderhoortest") in normal-hearing school-age children. Sub-aims were to study test-retest reliability, and the effects of presentation type and age on test results. DESIGN: An observational cross-sectional study at school. Speech reception thresholds (SRTs) were obtained through the online test in a training condition, and two test conditions: on a desktop computer and smartphone. The order of the test conditions was counterbalanced...

OBJECTIVE: This systematic review evaluated the effectiveness of two frequency-lowering schemes, non-linear frequency compression and frequency transposition, at improving speech intelligibility for adult hearing-impaired populations. DESIGN: A systematic search of 10 electronic databases was carried out using pre-defined inclusion criteria. Accepted articles were then critically appraised using the Effective Public Health Practice Project (EPHPP) Critical Appraisal Tool...

OBJECTIVE: Adolescent farmworkers are exposed to loud noise during farm activities. We present a prospective study that evaluated the efficacy of low-cost, technology-based intervention approaches in high schools to enhance the use of hearing protection among adolescent farmworkers. DESIGN: Six high schools in Iowa that agreed to participate in the study were divided into three equal groups through cluster-randomisation with each group receiving one of the three formats of hearing protection intervention: (a) classroom training, (b) classroom training coupled with smartphone app training and (c) computer training...

OBJECTIVE: The feasibility and repeatability of neonate auditory brainstem responses (ABRs) with a controlled hand-held applied force gauge for bone-conducted stimulus delivery was examined. DESIGN: A repeated measures test-retest design was employed. STUDY SAMPLE: Participants were 27 healthy neonates. A 4000 Hz bone-conducted CE-Chirp octave band stimulus evoked the ABRs. Intra- and intertester conditions were employed with a prototype hand-held applied force gauge (Etymōtic Research) attached to the superior aspect of the bone vibrator...
