Vestibular Function Modulates the Benefit of Hearing Aids in People With Hearing Loss During Static Postural Control.

Ear Hear 2019 Apr 5. Epub 2019 Apr 5.

École d'orthophonie et d'audiologie, Université de Montréal, Québec, Montréal, Canada.

Objectives: To evaluate the influence of auditory cues on postural sway in normal-hearing (NH) individuals, hearing-impaired individuals with vestibular impairment (HIVL), or hearing-impaired (HI) individuals without vestibular impairment.

Design: Thirty-two participants received a hearing and a vestibular evaluation (vHIT, oVEMP, cVEMP) and then were separated in to three groups (NH, HI, HIVL). All participants had to stand on a force platform in four postural conditions (A: EO/firm, B: EC/firm, C: EO/Foam, D: EC/Foam) under two auditory conditions, with or without auditory cues. Read More

The Use of Static and Dynamic Cues for Vowel Identification by Children Wearing Hearing Aids or Cochlear Implants.

Ear Hear 2019 Apr 10. Epub 2019 Apr 10.

Department of Audiology and Speech Pathology, The University of Tennessee Health Science Center, Knoxville, Tennessee, USA.

Objective: To examine vowel perception based on dynamic formant transition and/or static formant pattern cues in children with hearing loss while using their hearing aids or cochlear implants. We predicted that the sensorineural hearing loss would degrade formant transitions more than static formant patterns, and that shortening the duration of cues would cause more difficulty for vowel identification for these children than for their normal-hearing peers.

Design: A repeated-measures, between-group design was used. Read More

The Cost-Effectiveness of Bimodal Stimulation Compared to Unilateral and Bilateral Cochlear Implant Use in Adults with Bilateral Severe to Profound Deafness.

Ear Hear 2019 Apr 10. Epub 2019 Apr 10.

National Institute for Health Research (NIHR) Nottingham Biomedical Research Centre, Queens Medical Centre, Nottingham, United Kingdom.

Objectives: An increasing number of severe-profoundly deaf adult unilateral cochlear implant (CI) users receive bimodal stimulation; that is, they use a conventional acoustic hearing aid (HA) in their nonimplanted ear. The combination of electric and contralateral acoustic hearing provides additional benefits to hearing and also to general health-related quality of life compared with unilateral CI use. Bilateral CI is a treatment alternative to both unilateral CI and bimodal stimulation in some healthcare systems. Read More

Understanding Variability in Individual Response to Hearing Aid Signal Processing in Wearable Hearing Aids.

Ear Hear 2019 Apr 10. Epub 2019 Apr 10.

Department of Preventive Medicine, Biostatistics Collaboration Center, Feinberg School of Medicine, Northwestern University.

Objectives: Previous work has suggested that individual characteristics, including amount of hearing loss, age, and working memory ability, may affect response to hearing aid signal processing. The present study aims to extend work using metrics to quantify cumulative signal modifications under simulated conditions to real hearing aids worn in everyday listening environments. Specifically, the goal was to determine whether individual factors such as working memory, age, and degree of hearing loss play a role in explaining how listeners respond to signal modifications caused by signal processing in real hearing aids, worn in the listener's everyday environment, over a period of time.

Effect of Compression on Musical Sound Quality in Cochlear Implant Users.

Ear Hear 2019 Mar 29. Epub 2019 Mar 29.

Department of Otolaryngology-Head & Neck Surgery, University of California, San Francisco, California, USA.

Objectives: Cochlear implant (CI) users frequently report poor sound quality while listening to music, although the specific parameters responsible for this loss of sound quality remain poorly understood. Audio compression, which reduces the dynamic range (DR) for a given sound, is a ubiquitous component of signal processing used by both CI and hearing aid technology. However, the relative impact of compression for acoustic and electric hearing on music perception has not been well studied, an important consideration especially given that most compression algorithms in CIs were developed to optimize speech perception.

Factors Affecting Bimodal Benefit in Pediatric Mandarin-Speaking Chinese Cochlear Implant Users.

Ear Hear 2019 Mar 14. Epub 2019 Mar 14.

Department of Head and Neck Surgery, David Geffen School of Medicine, UCLA, Los Angeles, California, USA.

Objectives: While fundamental frequency (F0) cues are important to both lexical tone perception and multitalker segregation, F0 cues are poorly perceived by cochlear implant (CI) users. Adding low-frequency acoustic hearing via a hearing aid in the contralateral ear may improve CI users' F0 perception. For English-speaking CI users, contralateral acoustic hearing has been shown to improve perception of target speech in noise and in competing talkers. Read More

Reliability of Measures Intended to Assess Threshold-Independent Hearing Disorders.

Ear Hear 2019 Mar 14. Epub 2019 Mar 14.

Boys Town National Research Hospital, Omaha, Nebraska, USA.

Objectives: Recent animal studies have shown that noise exposure can cause cochlear synaptopathy without permanent threshold shift. Because the noise exposure preferentially damaged auditory nerve fibers that processed suprathreshold sounds (low-spontaneous rate fibers), it has been suggested that synaptopathy may underlie suprathreshold hearing deficits in humans. Recently, several researchers have suggested measures to identify the pathology or pathologies underlying suprathreshold hearing deficits in humans based on results from animal studies; however, the reliability of some of these measures have not been assessed.

Bone Conduction Amplification in Children: Stimulation via a Percutaneous Abutment versus a Transcutaneous Softband.

Authors:
Andrea L Pittman

Ear Hear 2019 Mar 7. Epub 2019 Mar 7.

Department of Speech and Hearing Science, Arizona State University, Tempe, Arizona, USA.

Objectives: Research suggests that the speech perception of children using bone conduction amplification improves if the device is coupled to an implanted abutment rather than to a softband. The purpose of the present study was to determine if the benefit of direct stimulation via an abutment is limited to small improvements in speech perception or if similar or greater benefits occur for other auditory tasks important for learning and communication.

Design: Fourteen children (7 to 15 years of age) with bilateral conductive and three children with unilateral conductive or sensorineural hearing loss were enrolled. Read More

Auditory Localization and Spatial Release From Masking in Children With Suspected Auditory Processing Disorder.

Ear Hear 2019 Mar 7. Epub 2019 Mar 7.

School of Communication Sciences and Disorders, and the National Centre for Audiology, Western University, London, Ontario, Canada.

Objectives: We sought to investigate whether children referred to our audiology clinic with a complaint of listening difficulty, that is, suspected of auditory processing disorder (APD), have difficulties localizing sounds in noise and whether they have reduced benefit from spatial release from masking.

Design: Forty-seven typically hearing children in the age range of 7 to 17 years took part in the study. Twenty-one typically developing (TD) children served as controls, and the other 26 children, referred to our audiology clinic with listening problems, were the study group: suspected APD (sAPD).

Mechanisms of Localization and Speech Perception with Colocated and Spatially Separated Noise and Speech Maskers Under Single-Sided Deafness with a Cochlear Implant.

Ear Hear 2019 Mar 7. Epub 2019 Mar 7.

Department of Psychology, University of Minnesota, Minneapolis, Minnesota, USA.

Objectives: This study tested listeners with a cochlear implant (CI) in one ear and acoustic hearing in the other ear, to assess their ability to localize sound and to understand speech in collocated or spatially separated noise or speech maskers.

Design: Eight CI listeners with contralateral acoustic hearing ranging from normal hearing to moderate sensorineural hearing loss were tested. Localization accuracy was measured in five of the listeners using stimuli that emphasized the separate contributions of interaural level differences (ILDs) and interaural time differences (ITD) in the temporal envelope and/or fine structure.

Speech Envelope Enhancement Instantaneously Effaces Atypical Speech Perception in Dyslexia.

Ear Hear 2019 Mar 5. Epub 2019 Mar 5.

Department of Neurosciences, Research Group Experimental ORL, KU Leuven-University of Leuven, Leuven, Belgium and.

Objectives: Increasing evidence exists that poor speech perception abilities precede the phonological deficits typically observed in dyslexia, a developmental disorder in learning to read. Impaired processing of dynamic features of speech, such as slow amplitude fluctuations and transient acoustic cues, disrupts effortless tracking of the speech envelope and constrains the development of adequate phonological skills. In this study, a speech envelope enhancement (EE) strategy was implemented to reduce speech perception deficits by students with dyslexia. Read More

Ear Hear 2019 Feb 21. Epub 2019 Feb 21.

Department of Audiology and Speech Pathology, University of Melbourne, Carlton, Victoria, Australia.

Objectives: To compare threshold and comfortable levels between a first and second cochlear implant (CI) for children, and to consider if the degree of difference between CIs was related to the age at bilateral implantation or the time between implants. A secondary objective was to examine the changes in levels over time for each CI .

Design: Fifty-seven participants were selected from the 146 children and young adults who received a first Nucleus CI as a child, and received a second implant at the Royal Victorian Eye and Ear Hospital between September 2003 and December 2011. Read More

Benefit of Higher Maximum Force Output on Listening Effort in Bone-Anchored Hearing System Users: A Pupillometry Study.

Ear Hear 2019 Feb 21. Epub 2019 Feb 21.

Oticon Medical AB, Datavägen, Askim, Sweden.

Objectives: The aim of this study was to compare listening effort, as estimated via pupillary response, during a speech-in-noise test in bone-anchored hearing system (BAHS) users wearing three different sound processors. The three processors, Ponto Pro (PP), Ponto 3 (P3), and Ponto 3 SuperPower (P3SP), differ in terms of maximum force output (MFO) and MFO algorithm. The hypothesis was that listeners would allocate lower listening effort with the P3SP than with the PP, as a consequence of a higher MFO and, hence, fewer saturation artifacts in the signal.

Different Associations between Auditory Function and Cognition Depending on Type of Auditory Function and Type of Cognition.

Ear Hear 2019 Feb 22. Epub 2019 Feb 22.

Department of Behavioural Sciences and Learning, Linköping University, Linköping, Sweden.

Objectives: Previous studies strongly suggest that declines in auditory threshold can lead to impaired cognition. The aim of this study was to expand that picture by investigating how the relationships between age, auditory function, and cognitive function vary with the types of auditory and cognitive function considered.

Design: Three auditory constructs (threshold, temporal-order identification, and gap detection) were modeled to have an effect on four cognitive constructs (episodic long-term memory, semantic long-term memory, working memory, and cognitive processing speed) together with age that could have an effect on both cognitive and auditory constructs.

Auditory Evoked Responses in Older Adults With Normal Hearing, Untreated, and Treated Age-Related Hearing Loss.

Ear Hear 2019 Feb 11. Epub 2019 Feb 11.

Department of Speech and Hearing Sciences, University of Washington, Washington, USA.

Objectives: The goal of this study was to identify the effects of auditory deprivation (age-related hearing loss) and auditory stimulation (history of hearing aid use) on the neural registration of sound across two stimulus presentation conditions: (1) equal sound pressure level and (2) equal sensation level.

Design: We used a between-groups design, involving three groups of 14 older adults (n = 42; 62 to 84 years): (1) clinically defined normal hearing (≤25 dB from 250 to 8000 Hz, bilaterally), (2) bilateral mild-moderate/moderately severe sensorineural hearing loss who have never used hearing aids, and (3) bilateral mild-moderate/moderately severe sensorineural hearing loss who have worn bilateral hearing aids for at least the past 2 years.

Results: There were significant delays in the auditory P1-N1-P2 complex in older adults with hearing loss compared with their normal hearing peers when using equal sound pressure levels for all participants. Read More

Hearing Impairment and Perceived Clarity of Predictable Speech.

Ear Hear 2019 Jan 7. Epub 2019 Jan 7.

Linnaeus Centre HEaring And Deafness (HEAD), Swedish Institute for Disability Research (SIDR), Department of Behavioural Sciences and Learning, Linköping University, Sweden.

Objectives: The precision of stimulus-driven information is less critical for comprehension when accurate knowledge-based predictions of the upcoming stimulus can be generated. A recent study in listeners without hearing impairment (HI) has shown that form- and meaning-based predictability independently and cumulatively enhance perceived clarity of degraded speech. In the present study, we investigated whether form- and meaning-based predictability enhanced the perceptual clarity of degraded speech for individuals with moderate to severe sensorineural HI, a group for whom such enhancement may be particularly important.

Effects of Phantom Electrode Stimulation on Vocal Production in Cochlear Implant Users.

Ear Hear 2018 Dec 21. Epub 2018 Dec 21.

Department of Otolaryngology-Head and Neck Surgery, University of California, San Francisco, California, USA.

Objectives: Cochlear implant (CI) users suffer from a range of speech impairments, such as stuttering and vocal control of pitch and intensity. Though little research has focused on the role of auditory feedback in the speech of CI users, these speech impairments could be due in part to limited access to low-frequency cues inherent in CI-mediated listening. Phantom electrode stimulation (PES) represents a novel application of current steering that extends access to low frequencies for CI recipients. Read More

Ear Hear 2018 Dec 31. Epub 2018 Dec 31.

Department of Otolaryngology-Head and Neck Surgery, Indiana University School of Medicine, Indianapolis, Indiana, USA.

Objectives: The objective of the present study was to determine whether long-term cochlear implant (CI) users would show greater variability in rapid phonological coding skills and greater reliance on slow-effortful compensatory executive functioning (EF) skills than normal-hearing (NH) peers on perceptually challenging high-variability sentence recognition tasks. We tested the following three hypotheses: First, CI users would show lower scores on sentence recognition tests involving high speaker and dialect variability than NH controls, even after adjusting for poorer sentence recognition performance by CI users on a conventional low-variability sentence recognition test. Second, variability in fast-automatic rapid phonological coding skills would be more strongly associated with performance on high-variability sentence recognition tasks for CI users than NH peers.

Masked Sentence Recognition in Children, Young Adults, and Older Adults: Age-Dependent Effects of Semantic Context and Masker Type.

Ear Hear 2018 Dec 28. Epub 2018 Dec 28.

Department of Otolaryngology/Head and Neck Surgery, University of North Carolina, Chapel Hill, North Carolina, USA.

Objectives: Masked speech recognition in normal-hearing listeners depends in part on masker type and semantic context of the target. Children and older adults are more susceptible to masking than young adults, particularly when the masker is speech. Semantic context has been shown to facilitate noise-masked sentence recognition in all age groups, but it is not known whether age affects a listener's ability to use context with a speech masker.

Masking Release for Speech in Modulated Maskers: Electrophysiological and Behavioral Measures.

Ear Hear 2018 Dec 14. Epub 2018 Dec 14.

Department of Otolaryngology-Head & Neck Surgery.

Objectives: The purpose of this study was to obtain an electrophysiological analog of masking release using speech-evoked cortical potentials in steady and modulated maskers and to relate this masking release to behavioral measures for the same stimuli. The hypothesis was that the evoked potentials can be tracked to a lower stimulus level in a modulated masker than in a steady masker and that the magnitude of this electrophysiological masking release is of the same order as that of the behavioral masking release for the same stimuli.

Design: Cortical potentials evoked by an 80-ms /ba/ stimulus were measured in two steady maskers (30 and 65 dB SPL), and in a masker that modulated between these two levels at a rate of 25 Hz. Read More

How Do You Deal With Uncertainty? Cochlear Implant Users Differ in the Dynamics of Lexical Processing of Noncanonical Inputs.

Ear Hear 2018 Dec 6. Epub 2018 Dec 6.

Department of Psychological and Brain Sciences, University of Iowa, Iowa City, Iowa, USA.

Objectives: Work in normal-hearing (NH) adults suggests that spoken language processing involves coping with ambiguity. Even a clearly spoken word contains brief periods of ambiguity as it unfolds over time, and early portions will not be sufficient to uniquely identify the word. However, beyond this temporary ambiguity, NH listeners must also cope with the loss of information due to reduced forms, dialect, and other factors. Read More

Development of the Cochlear Implant Quality of Life Item Bank.

Ear Hear 2018 Dec 6. Epub 2018 Dec 6.

Department of Otolaryngology-Head and Neck Surgery.

Objectives: Functional outcomes following cochlear implantation have traditionally been focused on word and sentence recognition, which, although important, do not capture the varied communication and other experiences of adult cochlear implant (CI) users. Although the inadequacies of speech recognition to quantify CI user benefits are widely acknowledged, rarely have adult CI user outcomes been comprehensively assessed beyond these conventional measures. An important limitation in addressing this knowledge gap is that patient-reported outcome measures have not been developed and validated in adult CI patients using rigorous scientific methods.

Normalizing cVEMPs: Which Method Is the Most Effective?

Ear Hear 2018 Nov 13. Epub 2018 Nov 13.

Department of Otology and Laryngology, Harvard Medical School, Boston, Massachusetts, USA.

Objectives: To determine the most effective method for normalizing cervical vestibular evoked myogenic potentials (cVEMPs).

Design: cVEMP data from 20 subjects with normal hearing and vestibular function were normalized using 16 combinations of methods, each using one of the 4 modes of electromyogram (EMG) quantification described below. All methods used the peak to peak value of an averaged cVEMP waveform (VEMPpp) and obtained a normalized cVEMP by dividing VEMPpp by a measure of the EMG amplitude. Read More

Ear Hear 2018 Nov 8. Epub 2018 Nov 8.

Advanced Bionics, LLC, Valencia, California, USA.

Objectives: A positive relation between audibility and speech understanding has been established for cochlear implant (CI) recipients. Sound field thresholds of 20 dB HL across the frequency range provide CI users the opportunity to understand soft and very soft speech. However, programming the sound processor to attain good audibility can be time-consuming and difficult for some patients. Read More

Biomarkers of Systemic Inflammation and Risk of Incident Hearing Loss.

Ear Hear 2018 Nov 5. Epub 2018 Nov 5.

Channing Division of Network Medicine, Department of Medicine, Brigham and Women's Hospital, Boston, Massachusetts, USA.

Background: Chronic inflammation may lead to cochlear damage, and the only longitudinal study that examined biomarkers of systemic inflammation and risk of hearing loss found an association with a single biomarker in individuals <60 years of age. The purpose of our study was to determine whether plasma inflammatory markers are associated with incident hearing loss in two large prospective cohorts, Nurses' Health Studies (NHS) I and II.

Methods: We examined the independent associations between plasma levels of markers of systemic inflammation (C-reactive protein [CRP], interleukin-6 [IL-6], and soluble tumor necrosis factor receptor 2 [TNFR-2]) and self-reported hearing loss. Read More
