[Disproportionately high loss in speech intelligibility].

Background: The influence of hearing impairment on everyday hearing can be estimated by speech audiometry. There is a great deal of variability in the dependence of word recognition scores on pure-tone hearing loss.

Materials And Methods: A large clinical database of 28,261 records with complete tone and speech audiometry data was analyzed.

Impact of unilateral vs. bilateral evaluation on cochlear implant candidacy.

Background: The indication criteria for cochlear implantation differ considerably across regions.

Objectives: To estimate the effects of different candidacy criteria on the number of cochlear implant (CI) candidates.

Methods: We analysed a very large clinical audiological database comprising pure-tone thresholds and speech-audiometric data in order to identify CI candidates on the basis of different audiometric candidacy criteria.

Evolving a Model for Cochlear Implant Outcome.

Background: Cochlear implantation is an efficient treatment for postlingually deafened adults who do not benefit sufficiently from acoustic amplification. Implantation is indicated when it can be foreseen that speech recognition with a cochlear implant (CI) is superior to that with a hearing aid. Especially for subjects with residual speech recognition, it is desirable to predict CI outcome on the basis of preoperative audiological tests.

Validation of a predictive model for speech discrimination after cochlear impIant provision.

Background: If sufficient speech discrimination is no longer achieved with conventional hearing systems, an audiological indication for a cochlear implant (CI) is given. However, there are no established target criteria for CI aftercare with regard to the level of speech comprehension to be achieved. The aim of this study is to validate an existing predictive model for speech comprehension after CI provision.

Speech Perception in Bilateral Hearing Aid Users With Different Grades of Asymmetric Hearing Loss.

Hearing loss is associated with decreased speech perception as well as with changes in the auditory pathway. The effects of those changes on binaural speech perception with hearing aids are not yet fully understood. To provide further evidence on the functional changes of the auditory pathway, several speech perception tests (unilateral and bilateral, aided and unaided, in quiet, and in noise) were conducted in a population of 370 bilateral hearing aid users covering the entire range of the World Health Organization's most recent classification of hearing loss.

Fluctuation in electrical hearing in a Morbus Meniere's patient.

The glycerol test is an easy-to-use instrument to elucidate fluctuations of electrical hearing in patients with Meniere's disease and it might be also used as a therapeutic option.

Cochlear Implantation in Candidates With Moderate-to-Severe Hearing Loss and Poor Speech Perception.

Objectives/hypothesis: To determine the improvement in word recognition score (WRS ) after cochlear implant (CI) surgery in hearing aid (HA) users with preoperative hearing threshold ≤80 dB HL and inadequate speech recognition scores with HA. Secondarily, to identify predictive factors for WRS with a CI (WRS [CI]) 6 months after surgery, derived from the standard German CI preoperative assessment.

Study Design: Retrospective chart review.

Speech recognition with hearing aids for 10 standard audiograms : English version.

Background: Improvement of speech perception in quiet is an important goal of hearing aid provision. In practice, results are highly variable. The aim of this study was to investigate the relationship between type and extent of hearing loss (audiogram type), maximum word recognition score, and aided speech perception.

[Subjective improvement of hearing through cochlear implantation].

Background: During the past few decades various questionnaires have been developed to evaluate quality of life using audiological measures. The Hearing Implant Sound Quality Index (HISQUI) was developed especially for patients with a cochlear implant (CI). The aim of this study was to evaluate subjective hearing improvement after CI surgery and to correlate the results with objective measuring methods such as pure-tone and speech audiometry.

A short feature vector for image matching: The Log-Polar Magnitude feature descriptor.

The choice of an optimal feature detector-descriptor combination for image matching often depends on the application and the image type. In this paper, we propose the Log-Polar Magnitude feature descriptor-a rotation, scale, and illumination invariant descriptor that achieves comparable performance to SIFT on a large variety of image registration problems but with much shorter feature vectors. The descriptor is based on the Log-Polar Transform followed by a Fourier Transform and selection of the magnitude spectrum components.

[Longterm Results of a Screening Procedure for Adult Cochlear Implant Candidates].

This study gives an estimation of the long term outcome of a screening procedure for cochlear implant candidacy in hearing aid users.In a recent retrospective study, hearing aid performance and audiometric measures in 185 subjects (318 ears) were analyzed. In the context of 2 years follow-up, the outcome of the ipsilateral screening procedure was analyzed.

[Speech audiometry for indication of conventional and implantable hearing aids].

The social function of the human hearing apparatus is comprehension of speech. Auditory rehabilitation aims to enhance speech perception in everyday life. Consequently, audiological evaluation contains speech perception measurement.

Speech Perception and Information-Carrying Capacity for Hearing Aid Users of Different Ages.

Hearing impairment in the elderly is usually treated with conventional hearing aids; however, a large number of older people do not achieve sufficient speech recognition with hearing aids. The aim of the study was to describe speech perception with hearing aids in comparison to pure-tone hearing loss and maximum speech recognition scores for phonemically balanced words. Data from 392 hearing aid users with different degrees of hearing loss were evaluated retrospectively.

Objective: The primary objective of this study was the comparison of younger and older (>75 yr) CI recipients' performance for speech perception in quiet and in competing continuous and fluctuating noise.

Study Design: Prospective, comparative clinical study.

Setting: University hospital.

Audiometry-Based Screening Procedure for Cochlear Implant Candidacy.

Objective: This study defines a screening procedure for cochlear implant (CI) candidacy in hearing aid users by using simple audiometric measures.

Methods: Within this retrospective study, hearing aid performance and audiometric measures in 185 subjects (318 ears) were analyzed. By means of a linear Naive Bayes classifier, the pure-tone average and the maximum monosyllabic score (PB(max)) were used to predict the aided monosyllabic word score and CI candidacy.

Automated classification of glandular tissue by statistical proximity sampling.

Due to the complexity of biological tissue and variations in staining procedures, features that are based on the explicit extraction of properties from subglandular structures in tissue images may have difficulty generalizing well over an unrestricted set of images and staining variations. We circumvent this problem by an implicit representation that is both robust and highly descriptive, especially when combined with a multiple instance learning approach to image classification. The new feature method is able to describe tissue architecture based on glandular structure.

Image segmentation and identification of paired antibodies in breast tissue.

Comparing staining patterns of paired antibodies designed towards a specific protein but toward different epitopes of the protein provides quality control over the binding and the antibodies' ability to identify the target protein correctly and exclusively. We present a method for automated quantification of immunostaining patterns for antibodies in breast tissue using the Human Protein Atlas database. In such tissue, dark brown dye 3,3'-diaminobenzidine is used as an antibody-specific stain whereas the blue dye hematoxylin is used as a counterstain.

[Speech perception with hearing aids in comparison to pure-tone hearing loss].

Background And Aim: Speech perception is the most important social task of the auditory system. Consequently, speech audiometry is essential to evaluate hearing aid benefit. The aim of the study was to describe the correlation between pure-tone hearing loss and speech perception.

Speech performance and training effects in the cochlear implant elderly.

Objectives: Cochlear implantation requires acclimatization to the electrical input. Usually, cochlear implant (CI) listeners undergo an auditory rehabilitation program that includes auditory training sessions. Recently, it was shown that a phoneme-based training may improve speech perception abilities even in experienced CI listeners.
