Apogeotropic variant of horizontal semicircular canal benign paroxysmal positional vertigo: Where are the particles?

Audiol Res 2019 Sep 29;9(2):228. Epub 2019 Aug 29.

Department of Otorhinolaryngology, Pontifical Catholic University of Rio Grande do Sul, Porto Alegre.

The apogeotropic variant of horizontal semicircular canal benign paroxysmal positional vertigo (HC-BPPV) is attributed to free floating particles in the anterior arm of the lateral semicircular canal - particles attached to the cupula facing the canal or particles attached to the cupula facing the utricle. Zuma e Maia described a new treatment for both canalithiasis of the anterior arm of the horizontal semicircular canal (HC) and cupulolithiasis of the HC. Seventeen patients with apogeotropic HC-BPPV were enrolled and treated with Zuma's Maneuver. Read More

Effectiveness and efficiency of a dedicated bimodal fitting formula.

Audiol Res 2019 May 9;9(1):219. Epub 2019 May 9.

Advanced Bionics GmbH, European Research Center, Hannover, Germany.

The population of unilateral cochlear implant (CI) users with aidable residual hearing in the contralateral ear is continuously growing. Aiding the contralateral ear with a hearing aid has been shown to provide substantial benefit regarding speech intelligibility in quiet and in noise, sound quality, localization ability and listening effort. In this study, a dedicated hearing aid with the accompanying fitting prescription, tailored to the needs of bimodal listeners was evaluated in nine bimodal CI users. Read More

Vocalization frequency as a prognostic marker of language development following early cochlear implantation.

Audiol Res 2019 May 6;9(1):217. Epub 2019 May 6.

Faculty of Wellbeing, Education and Language Studies, Open University, London, UK.

Despite their potential significance for later linguistic outcomes, early aspects of vocalization had been seriously undervalued in the past, and thus, minimally investigated until relatively recently. The present article sets out to critically examine existing evidence to: i) ascertain whether vocalization frequency (volubility) posits a plausible marker of cochlear implantation success in infancy, and ii) determine the clinical usefulness of post-implementation vocalization frequency data in predicting later language development. Only recent peer-reviewed articles with substantial impact on vocalization growth during the first year of life, examining sound production characteristics of normally hearing (NH) and hearing impaired infants fitted with cochlear implantation (CI) were mentioned.

Free-field evoked auditory brainstem responses in cochlear implant users.

Audiol Res 2018 Oct 7;8(2):216. Epub 2018 Dec 7.

Systems Neuroscience & Neurotechnology Unit, Saarland University, Faculty of Medicine, Homburg/Saar and Saarland University of Applied Sciences, Saarbruecken.

The importance of binaural cues in auditory stream formation and sound source segregation is widely accepted. When treating one ear with a cochlear implant (CI) the peripheral auditory system gets partially replaced and processing delays get added potentially, thus important interaural time differences get altered. However, these effects are not fully understood, leaving a lack of systematic binaural fitting strategies with respect to an optimal binaural fusion. Read More

Effects of directional hearing aid settings on different laboratory measures of spatial awareness perception.

Audiol Res 2018 Oct 21;8(2):215. Epub 2018 Nov 21.

Institute of Clinical Research, University of Southern Denmark, Odense, Denmark.

Hearing loss can negatively influence the spatial hearing abilities of hearing-impaired listeners, not only in static but also in dynamic auditory environments. Therefore, ways of addressing these deficits with advanced hearing aid algorithms need to be investigated. In a previous study based on virtual acoustics and a computer simulation of different bilateral hearing aid fittings, we investigated auditory source movement detectability in older hearing- impaired (OHI) listeners.

Audiol Res 2018 Oct 2;8(2):214. Epub 2018 Oct 2.

Department of Communication Sciences and Disorders; Central Sensory Processes Laboratory, University of Texas at Austin, Austin, Texas, USA.

Decreased central inhibition, possibly related to hearing loss, may contribute to chronic tinnitus. However, many individuals with normal hearing thresholds report tinnitus, suggesting that the percept in this population may arise from sources other than peripheral deafferentation. One measure of inhibition is sensory gating. Read More

Transient Noise Reduction in Cochlear Implant Users: a Multi-Band Approach.

Audiol Res 2016 Aug 23;6(2):154. Epub 2016 Aug 23.

Department of Otolaryngology, Hannover Medical School , Hannover.

A previously-tested transient noise reduction (TNR) algorithm for cochlear implant (CI) users was modified to detect and attenuate transients independently across multiple frequency-bands. Since speech and transient noise are often spectrally distinct, we hypothesized that benefits in speech intelligibility can be achieved over the earlier single-band design. Fifteen experienced CI users (49 to 72 years) were tested unilaterally using pre-processed stimuli delivered directly to a speech processor. Read More

Automated Classification of Vowel Category and Speaker Type in the High-Frequency Spectrum.

Audiol Res 2016 Apr 20;6(1):137. Epub 2016 Apr 20.

Lane Department of Computer Science and Electrical Engineering, West Virginia University , Morgantown, WV, USA.

The high-frequency region of vowel signals (above the third formant or F3) has received little research attention. Recent evidence, however, has documented the perceptual utility of high-frequency information in the speech signal above the traditional frequency bandwidth known to contain important cues for speech and speaker recognition. The purpose of this study was to determine if high-pass filtered vowels could be separated by vowel category and speaker type in a supervised learning framework. Read More

Safety of the HyperSound® Audio System in Subjects with Normal Hearing.

Audiol Res 2015 Jun 20;5(2):136. Epub 2015 Nov 20.

Seitzman Consulting , San Diego, CA, USA.

The objective of the study was to assess the safety of the HyperSound® Audio System (HSS), a novel audio system using ultrasound technology, in normal hearing subjects under normal use conditions; we considered pre-exposure and post-exposure test design. We investigated primary and secondary outcome measures: i) temporary threshold shift (TTS), defined as >10 dB shift in pure tone air conduction thresholds and/or a decrement in distortion product otoacoustic emissions (DPOAEs) >10 dB at two or more frequencies; ii) presence of new-onset otologic symptoms after exposure. Twenty adult subjects with normal hearing underwent a pre-exposure assessment (pure tone air conduction audiometry, tympanometry, DPOAEs and otologic symptoms questionnaire) followed by exposure to a 2-h movie with sound delivered through the HSS emitter followed by a post-exposure assessment.

Audiol Res 2015 Jun 16;5(2):133. Epub 2015 Jun 16.

All India Institute of Speech and Hearing , Mysuru, Karnataka, India.

Individuals with unilateral hearing loss of severe-profound degree face listening difficulties while localizing a sound source and while perceiving speech in the presence of noise. The objective was to compare the efficacy of the digitally programmable bone anchored hearing aid (BAHA), trimmer digital BAHA and the transcranial contralateral routing of signal (T-CROS) in improving the listening performance in adults with unilateral hearing loss. Twenty-four adults with unilateral hearing loss was assessed for sound field thresholds, speech perception performance in quiet and noise (direct and indirect conditions) and the subjective quality rating of speech in unaided and aided with either T-CROS or digitally programmable BAHA or trimmer digital BAHA attached to the headband.
