OBJECTIVE: To design a test battery and conduct a proof-of-concept experiment of a test method that can be used to measure the detection performance afforded by military advanced hearing protection devices (HPDs) and tactical communication and protective systems (TCAPS). DESIGN: The detection test was conducted with each of the four loudspeakers located at front, right, rear and left of the participant. Participants wore 2 in-ear-type TCAPS, 1 earmuff-type TCAPS, a passive Combat Arms Earplug in its "open" or pass-through setting and an EB-15LE™ electronic earplug...

OBJECTIVE: To characterise the performance of hearing protection devices (HPDs) in impulsive-noise conditions and to compare various protection metrics between impulsive and steady-state noise sources with different characteristics. DESIGN: HPDs were measured per the impulsive test methods of ANSI/ASA S12.42- 2010 . Protectors were measured with impulses generated by both an acoustic shock tube and an AR-15 rifle. The measured data were analysed for impulse peak insertion loss (IPIL) and impulsive spectral insertion loss (ISIL)...

OBJECTIVE: The aim of the study was, based on the individualisation of hearing aids (HA) and pre-sets for audio devices, to develop a questionnaire to determine the basis for profiling sound preferences and hearing habits to gather additional information usable for HA fitting and adjustment tools for audio-devices. METHODS: We developed a questionnaire consisting of 46 items. A postal survey was conducted with N = 622 users with a mean age of 66 years (47.9% aided with HA, 45...

OBJECTIVE: A generalised concept for hearing aid fitting and fine-tuning based on estimated individual traits is presented along first implementations in this report. DESIGN: To estimate the individual traits, a set of auditory model-based performance measures is used to generate promising candidates within the algorithm's parameter space for a subsequent subjective rating. For the subjective assessment, a fast and intuitive multi-stimulus test denoted as combined discrimination and classification (CoDiCl) is presented to capture user preferences for an optimised setting...

OBJECTIVE: To examine the relationship between hearing acuity and operational performance in simulated dismounted combat. DESIGN: Individuals wearing hearing loss simulation systems competed in a paintball-based exercise where the objective was to be the last player remaining. Four hearing loss profiles were tested in each round (no hearing loss, mild, moderate and severe) and four rounds were played to make up a match. This allowed counterbalancing of simulated hearing loss across participants...

OBJECTIVE: To analyse over 700,000 cross-sectional measurements from the Mine Safety and Health Administration (MHSA) and develop statistical models to predict noise exposure for a worker. DESIGN: Descriptive statistics were used to summarise the data. Two linear regression models were used to predict noise exposure based on MSHA-permissible exposure limit (PEL) and action level (AL), respectively. Twofold cross validation was used to compare the exposure estimates from the models to actual measurement...

OBJECTIVE: To investigate the effects of exposure to pesticides on the central auditory functions (CAF) of Brazilian tobacco growers. DESIGN: This was a cross-sectional study carried out between 2010 and 2012. Participants were evaluated with two behavioural procedures to investigate CAF, the random gap detection test (RGDT) and the dichotic digit test in Portuguese (DDT). STUDY SAMPLE: A total of 22 growers exposed to pesticides (study group) and 21 subjects who were not exposed to pesticides (control group) were selected...

OBJECTIVE: To determine whether acoustic reflexes are pervasive (i.e. sufficiently prevalent to provide 95% confidence of at least 95% prevalence) and might be invoked in damage-risk criteria (DRC) and health hazard assessments (HHA) for impulsive noise. DESIGN: Cross-sectional analyses of a nationally-representative study. STUDY SAMPLE: National Health and Nutrition Examination Survey (NHANES) data collected between 1999 and 2012 were used...

OBJECTIVE: In many low- and middle-income countries, the availability of hearing technology is limited, with few options for hearing aid repairs. Minimising moisture damage to hearing aid electronics improves function and longevity; however, desiccants that absorb moisture from hearing aid components are unavailable in many regions. This study compared the effectiveness of uncooked white rice and seven commercial silica gel desiccants in removing moisture from hearing aids. DESIGN: Relative humidity measurements in a test chamber were obtained from a water-saturated BTE hearing aid prior to and after placement in uncooked white rice and seven different silica gel desiccants...

OBJECTIVE: A discussion on whether recent research on noise-induced cochlear neuropathy in rodents justifies changes in current regulation of occupational noise exposure. DESIGN: Informal literature review and commentary, relying on literature found in the authors' files. No formal literature search was performed. STUDY SAMPLE: Published literature on temporary threshold shift (TTS) and cochlear pathology, in humans and experimental animals, as well as the regulations of the US Occupational Safety and Health Administration (OSHA)...

OBJECTIVE: To study the relationship of life-time noise exposure and experience of tinnitus. DESIGN: Audiometric measures included otoscopy, pure tone air- and bone-conduction hearing threshold levels (HTL) and otoacoustic emissions (OAEs). Participants completed questionnaires including demographic information, past hearing health, history of participation in loud leisure activities, and attitudes to noise. STUDY SAMPLE: A representative sample (1435) of the young (11-35 years old) Australian population...

OBJECTIVES: Otitis media with effusion (OME) is the presence of non-purulent inflammation in the middle ear. Hearing impairment is frequently associated with OME. Pure tone audiometry and speech audiometry are two of the most primarily utilised auditory assessments and provide valuable behavioural and functional estimation on hearing loss. This paper was designed to review and analyse the effects of the presence of OME on children's listening abilities. DESIGN: A systematic and descriptive review...

OBJECTIVE: Create virtual acoustic environments (VAEs) with interactive dynamic rendering for applications in audiology. DESIGN: A toolbox for creation and rendering of dynamic virtual acoustic environments (TASCAR) that allows direct user interaction was developed for application in hearing aid research and audiology. The software architecture and the simulation methods used to produce VAEs are outlined. Example environments are described and analysed. CONCLUSION: With the proposed software, a tool for simulation of VAEs is available...

OBJECTIVE: The primary aim of this study was to evaluate the effect of coupling method on telephone-based speech recognition and perceived listening difficulty in noise for cochlear implant (CI) users. A secondary aim was to evaluate potential impacts of additional processing modifications within coupling conditions, such as activating noise reducing algorithms or muting environmental microphones. DESIGN: Hochmair-Schulz-Moser sentences were bandpass-filtered (300-3400 Hz) and presented unilaterally either via telephone handset or advanced wireless streaming device in a background of cafeteria babble (signal-to-noise ratio =15 dB)...

DESIGN: The study involved a cross-sectional survey design. Participants provided demographic details and completed the Kannada and English (original) version of the HHQ questionnaire. To evaluate test-retest reliability, ∼50% of the participants completed the Kannada version for the second time after 15 days...

OBJECTIVE: To explore parent perceptions of communication and academic experiences of cochlear implant (CI) recipients under the age of 18. DESIGN: Cross-sectional survey design. Two surveys (K-12, birth-5) queried parent perceptions of the impact of CI on communication, listening in various environments and academic achievement. Surveys contained 16-23 multiple choice and/or Likert ratings, plus four open-ended questions to assess reasons for obtaining a CI, satisfaction with CI and suggestions for professionals...
