Use of custom-moulded earmoulds to improve repeatability of DPOAE map measurements.

Int J Audiol 2020 Oct 12:1-6. Epub 2020 Oct 12.

Geisel School of Medicine at Dartmouth, Lebanon, NH, USA.

Objective: Distortion product otoacoustic emission (DPOAE) mapping characterises cochlear function, can include both the 2f1-2f2 and 2f2-2f1 DPOAEs, and shows promise for tracking cochlear changes. DPOAE amplitude measurements are not as repeatable longitudinally as pure-tone audiometry, likely due in part to probe placement sensitivity. We hypothesised that DPOAE level map variation over multiple testing sessions could be minimised by replacing traditional rubber tips with custom-moulded probe tips. Read More

Hearing outcome measures for conductive and mixed hearing loss treatment in adults: a scoping review.

Int J Audiol 2021 Apr 26;60(4):239-245. Epub 2020 Sep 26.

The Cambridge Hearing Group, University of Cambridge, Cambridge, UK.

Objective: Rehabilitation options for conductive and mixed hearing loss are continually expanding, but without standard outcome measures comparison between different treatments is difficult. To meaningfully inform clinicians and patients core outcome sets (COS), determined via a recognised methodology, are needed. Following our previous work that identified hearing, physical, economic and psychosocial as core areas of a future COS, the AURONET group reviewed hearing outcome measures used in existing literature and assigned them into different domains within the hearing core area.

[Preventive hearing tests in workers exposed to noise and organic solvents].

Med Pr 2020 Jul 9;71(4):493-505. Epub 2020 Jul 9.

Instytut Medycyny Pracy im. prof. J. Nofera / Nofer Institute of Occupational Medicine, Łódź, Poland (Klinika Audiologii i Foniatrii / Department of Audiology and Phoniatrics).

Robust evidence confirms that occupational exposures to organic solvents are ototoxic and can aggravate the effects of noise on the auditory organ. Accordingly, Directive 2003/10/EC of the European Parliament and of the Council recommends that in assessing the risk of occupational hearing loss, the interaction of noise and organic solvents to hearing should be taken into account. Given that no prophylactic recommendations have been established to date, this study is intended to provide physicians with guidance in conducting audiometric tests in workers exposed to noise and organic solvents.

Frequency Following Response and Speech Recognition Benefit for Combining a Cochlear Implant and Contralateral Hearing Aid.

Trends Hear 2020 Jan-Dec;24:2331216520902001

Department of Hearing and Speech Sciences, Vanderbilt University Medical Center, Nashville, TN, USA.

Multiple studies have shown significant speech recognition benefit when acoustic hearing is combined with a cochlear implant (CI) for a bimodal hearing configuration. However, this benefit varies greatly between individuals. There are few clinical measures correlated with bimodal benefit and those correlations are driven by extreme values prohibiting data-driven, clinical counseling. Read More

Auditory, video head impulse test and vestibular evoked myogenic potentials findings in adults with human immunodeficiency virus.

Auris Nasus Larynx 2020 Jun 18;47(3):367-376. Epub 2019 Dec 18.

Department of Internal Medicine, Steve Biko Academic Hospital, Private bag X20, Hatfield 0028, Pretoria, South Africa.

Objectives: Even though there is an association between hearing loss and human immunodeficiency virus (HIV), particularly in low- and middle-income countries, further research is needed to investigate the nature of such hearing loss. Likewise, despite documented vestibular alterations in people with HIV, the true occurrence, presentation, and nature of these manifestations are yet to be established. Advances in technology for vestibular testing has allowed for objective site-of-lesion tests such as the video head impulse test (vHIT), cervical vestibular evoked myogenic potentials (cVEMPs) and ocular vestibular evoked myogenic potential (oVEMPs).

Are There Cochlear Dead Regions Involved in Hearing Loss after Cisplatin Ototoxicity?

Audiol Neurootol 2019 29;24(5):253-257. Epub 2019 Oct 29.

Department of Audiology, AC Camargo Cancer Center, São Paulo, Brazil.

Background: The most common complaint of patients affected by chemotherapy-induced hearing loss is difficulty understanding speech in noisy environments despite the use of hearing aids. Cochlear dead regions, those areas with damaged or absent inner hair cells and dendrites, may account for this type of hearing loss. However, it is unknown whether this condition is associated with cisplatin agents. Read More

FreeHear: A New Sound-Field Speech-in-Babble Hearing Assessment Tool.

Trends Hear 2019 Jan-Dec;23:2331216519872378

Manchester Centre for Audiology and Deafness, School of Health Sciences, University of Manchester, UK.

Pure-tone threshold audiometry is currently the standard test of hearing. However, in everyday life, we are more concerned with listening to speech of moderate loudness and, specifically, listening to a particular talker against a background of other talkers. FreeHear delivers strings of three spoken digits (0-9, not 7) against a background babble via three loudspeakers placed in front and to either side of a listener. Read More
