Implantable Middle Ear Hearing Devices: A Review

Seminars in Hearing — Thu, 11 Mar 2010 18:10:54 +0100

Semin Hear 2010; 31: 028-036DOI: 10.1055/s-0029-1246322ABSTRACTImplantable middle ear hearing devices (IMEHDs) were developed in an effort to improve on the limitations of traditional hearing aids. The last few years have seen significant advances in this technology with the emergence of several new devices, including fully implantable prostheses. As more patients are being implanted, experience with these devices has increased and refinements have been made. The indications also have expanded to include patients with mixed hearing loss in addition to those with pure sensorineural hearing loss, with application of the transducer to either the ossicles or the oval or round window. Fully implantable devices also are gaining ground, although most of these are relatively new and are still in t...

NAD Commends Google Roll-Out of Automatic Captions

National Association of the Deaf — Fri, 05 Mar 2010 01:30:21 +0100

The National Association of the Deaf (NAD) applauds Google’s decision to roll out auto-captioning for YouTube. All YouTube videos in English that have a clear audio track can be automatically captioned. In addition, Google has made turning on captions much easier by allowing YouTube account holders to set up closed captions to be “on” for all videos they view. Google also plans to provide the universal “CC” icon on the video player whenever possible.read more (Source: National Association of the Deaf)

beta-Bungarotoxin application to the round window: An in vivo deafferentation model of the inner ear.

Hearing Research — Mon, 22 Feb 2010 00:00:00 +0100

Authors: Palmgren B, Jin Z, Ma H, Jiao Y, Olivius P Hearing impairment can be caused by a primary lesion to the spiral ganglion neurons (SGNs) with the hair cells kept intact, for example via tumours, trauma or auditory neuropathy. To mimic these conditions in animal models various methods of inflicting damage to the inner ear have been used. However, only a few methods have a selective effect on the SGNs, which is of importance since it might be clinically more relevant to study hearing impairment with the hair cells undamaged. beta-Bungarotoxin is a venom of the Taiwan banded krait, which in vitro has been shown to induce apoptosis in neurons, leaving remaining cochlear cells intact. We wanted to create an in vivo rat model of selective damage to primary auditory neurons. Under deep ...

Measuring the quasi-static Young's modulus of the eardrumusing an indentation technique.

Hearing Research — Sun, 07 Feb 2010 00:00:00 +0100

In this study, we adapted a tissue indentation technique and inverse finite-element analysis to estimate the Young's modulus of the eardrum. A custom-built indentation apparatus was used to perform indentation testing on seven rat eardrums in situ after immobilizing the malleus. Testing was done in most cases on the posterior pars tensa. The unloaded shape of each eardrum was measured and used to construct finite-element models with subject-specific geometries to simulate the indentation experiment. The Young's modulus of each specimen was then estimated by numerically optimizing the Young's modulus of each model so that simulation results matched corresponding experimental data. R1-2: Using an estimated value of 12 mum for the thickness of each model eardrum, the estimated average Young's...

The Importance of Culture and ASL Night!

NAD YLC Blog — Tue, 21 Jul 2009 07:45:00 +0100

Vlog by FireflyCalisthenics? We are so up for it! At the beginning of YLC, most of us didn’t like morning exercises, but today it started to grow on us. The campers will return to home and continue their morning calisthenics, we hope! Morning exercises rock our socks off!We had a guest speaker today! From Rochester, New York, we welcomed Dr. Peter Hauser to YLC! Peter graduated from Central Connecticut State University in 1994. He then went to Gallaudet University, where he obtained his MA degree in 1998 and his PhD degree in 2000. He currently works as the Director of Deaf Studies Lab at NTID and as Director of Neurocongitive Research at Gallaudet. Today he gave us, the YLCERS, a workshop on “Cultural Knowledge: Identity and Cultural Capital.” We learned that deaf and hearing people...

Service-learning: recentering the deaf community in interpreter education.

American Annals of the Deaf — Mon, 07 Dec 2009 04:02:03 +0100

Authors: Shaw S, Roberson L The concept of recentering the Deaf community in interpreter education stems from the recent discussion of program evolution away from stakeholders and into academia highlighted by Monikowski and Peterson (2005). The University of North Florida, in the initial stages of developing a B.S. degree and M.Ed. concentration in ASL/English Interpreting, responded by developing stand-alone courses in service-learning, with hopes of prioritizing the needs of the Deaf community in curriculum development. The program was implemented in fall 2007, and the first cohort of students completed its second course in service-learning in fall 2008. Elements of the new program that indicate its progress toward recentering include an overview of service-learning as pedagogy in ac...

Update on Toll Free Numbers

National Association of the Deaf — Wed, 10 Mar 2010 17:26:23 +0100

Video: The NAD, working with TDI and other consumer groups, advocated strongly for the Federal Communications Commission (FCC) to allow people to use VRS and IP Relay toll free numbers (800 or 866 numbers) the same way hearing people use toll free numbers. See the NAD Consumer Alert for more information. Today, as a result of these efforts, all calls to VRS and IP Relay toll free numbers are connected. The FCC will review and may develop new policies for toll free numbers. Here are some things the FCC may consider. read more (Source: National Association of the Deaf)

Progress Towards Universal Neonatal Hearing Screening: A World Review

Australian and New Zealand Journal of Audiology — Mon, 22 Jun 2009 23:00:00 +0100

This study reviewed the performance of universal neonatal hearing screening (UNHS) programs in 46 countries across North America, Europe, Asia, the Middle East, Oceania and Africa. The review was based on data collected from a 2004 survey of early hearing detection programs; responses to a 2006 survey of audiologists undertaken by the authors; a literature review of 55 articles, reports and internet sources from 1995 to 2007; and one 2006 Market Research Report. This data was compared to the UNHS benchmarks set by the Joint Committee on Infant Hearing (JCIH) in 2007. In the 21 countries where data on national screening coverage were available, the average coverage was 46% (JCIH recommends 95% or more). In the 32 countries where data on regional or local screening coverage were available, t...

Sound Localization by Cochlear Implant Users

Seminars in Hearing — Thu, 11 Mar 2010 18:10:54 +0100

This article attempts to sort through the variables and find commonalities in the research. It is clear that the majority of adults with bilateral cochlear implants are much better at horizontal localization with two implants compared with one, but their abilities do not reach those of normal-hearing listeners. The localization results for children and for bimodal (cochlear implant in one ear, hearing aid in the other) listeners are less clear, with some improvement over monaural listening, but not for all subjects.[...]© Thieme Medical PublishersGet connected:Table of contents | Abstract | Full text (Source: Seminars in Hearing)

Intelligibility of interrupted and interleaved speech for normal-hearing listeners and cochlear implantees.

Hearing Research — Sat, 27 Feb 2010 00:00:00 +0100

Authors: Gnansia D, Pressnitzer D, Péan V, Meyer B, Lorenzi C Speech intelligibility is degraded in the presence of a competing talker for cochlear implantees, presumably because of impaired tracking and integration of speech segments glimpsed in the masker valleys. This hypothesis was tested by assessing the intelligibility of periodically-interrupted bisyllables produced by a male and female talker, for normal-hearing listeners and implantees. A 4-Hz square-wave modulator with random phase was used to interrupt bisyllables from each talker. Stimuli were either presented alone (Experiment I) or interleaved (Experiment II: the two talkers were alternated). In experiment I, the mean identification score for each voice was 88% for normal-hearing listeners, and 35% for implantees. In...
