We conducted an analysis to assess the relative contribution of auditory brainstem response (ABR) testing and auditory steady-state response (ASSR) testing in providing appropriate hearing aid fitting in hearing-impaired children with difficult or unreliable behavioral audiometry. Of 150 infants and children who had been referred to us for hearing assessment as part of a neonatal hearing screening and cochlear implantation program, we identified 5 who exhibited significant discrepancies between click-ABR and ASSR testing results and difficult or unreliable behavioral audiometry...

REVIEW
T Steffens, S C Marcrum
For Ear, Nose & Throat specialists, the physiological and psychoacoustical deficits related to hearing impairment and the compensatory capabilities of hearing aids are topics of prime importance. In conductive hearing loss, the foremost deficit is decreased audibility, for which hearing aids can compensate almost entirely through the use of level independent gain. In the instance of sensorineural hearing loss, however, the irreversible loss of outer and inner hair cells causes a distorted sound perception, which is particularly troublesome when trying to understand speech in noisy environments...

Jaipreet Virdi, Coreen McGuire
The provision of standardized hearing aids is now considered to be a crucial part of the UK National Health Service. Yet this is only explicable through reference to the career of a woman who has, until now, been entirely forgotten. Dr Phyllis Margaret Tookey Kerridge (1901-1940) was an authoritative figure in a variety of fields: medicine, physiology, otology and the construction of scientific apparatus. The astounding breadth of her professional qualifications allowed her to combine features of these fields and, later in her career, to position herself as a specialist to shape the discipline of audiometry...

People with speech, hearing, or mental impairment require special communication assistance, especially for medical purposes. Automatic solutions for speech recognition and voice synthesis from text are poor fits for communication in the medical domain because they are dependent on error-prone statistical models. Systems dependent on manual text input are insufficient. Recently introduced systems for automatic sign language recognition are dependent on statistical models as well as on image and gesture quality...

INTRODUCTION: The prevalence of chronic otitis media with effusion (COME), and Eustachian tube dysfunction (ETD) is high in Down syndrome (DS) patients. This often necessitates multiple tympanostomy tube (TT) placements resulting in a higher rate of persistent tympanic membrane (TM) perforation requiring tympanoplasty for repair. OBJECTIVES: To assess risk factors for persistent perforation and outcomes of tympanoplasty in DS patients. METHODS: Retrospective case series of 91 ears in 69 DS patients with TM perforations, who were either observed or underwent tympanoplasty...

The signal-to-noise ratio (SNR) benefit of hearing aid directional microphones is dependent on the angle of the listener relative to the target, something that can change drastically and dynamically in a typical group conversation. When a new target signal is significantly off-axis, directional microphones lead to slower target orientation, more complex movements, and more reversals. This raises the question of whether there is an optimal design for directional microphones. In principle an ideal microphone would provide the user with sufficient directionality to help with speech understanding, but not attenuate off-axis signals so strongly that orienting to new signals was difficult or impossible...

Introduction: Most implantable hearing aids currently available were developed to compensate the sensorineural hearing loss by driving middle ear structures (e.g., the ossicles). These devices are successfully used in round window (RW) stimulation clinically, although this was initially not the intended use. Here, a novel microactuator, specifically designed for RW stimulation, was tested in human temporal bones to determine actuator performance and applicability. Methods: Stapes footplate response to RW stimulation was determined experimentally in human temporal bones and the obtained sound pressure output level was estimated...

OBJECTIVES: Normalizing perceived loudness is an important rationale for gain adjustments in hearing aids. It has been demonstrated that gains required for restoring normal loudness perception for monaural narrowband signals can lead to higher-than-normal loudness in listeners with hearing loss, particularly for binaural broadband presentation. The present study presents a binaural bandwidth-adaptive dynamic compressor (BBDC) that can apply different gains for narrow- and broadband signals...

Word recognition includes the activation of a range of syntactic and semantic knowledge that is relevant to language interpretation and reference. Here we explored whether or not the number of arguments a verb takes impinges negatively on verb processing time. In this study, three experiments compared the dynamics of spoken word recognition for verbs with different preferred argument structure. Listeners' eye movements were recorded as they searched an array of pictures in response to hearing a verb. Results were similar in all the experiments...
