| In this contribution we investigate the performance of RS coded DS-CDMA using M-ary orthogonal signalling over multipath Rayleigh fading channels. `ErrorsAnd-Erasures (EAE)' RS decoding is considered, where erasures are declared based on the joint Maximum Output and Ratio Threshold Test (MOR-TT). Two classes of diversity reception techniques suitable for noncoherent M-ary detection are invoke...

The availability of a compact disc with a female speaker for clinical use has raised the issue of the equivalence between the female speaker and the previous standard male speaker for assessing the speech reception threshold (SRT). This study evaluated the relationship of two- and three-frequency averages to the SRT for a male speaker on an audio tape and a female speaker on a compact disc in t...

The aim of this study was to examine the effects of speech rate on children's performance on a widely used language comprehension test, the Test for Reception of Grammar, version 2 (TROG'2), and to explore how test performance interacts with task difficulty and with the child's working memory capacity. Participants were 102 typically-developing Swedish-speaking children randomly assigned to one...

The speech perception ability reported from profoundly hearing-impaired persons using hearing aids or cochlear implants varies widely. A test battery was constructed that consisted of segmental and suprasegmental tasks and connected speech presented in three digerent modalities: visual (V), auditive (A) and audiovisual (AV). Two groups of patients participated. Fifeen subjects with a profound h...

INTRODUCTION  In the dentistry practice, dentists are exposed to harmful effects caused by several factors, such as the noise produced by their work instruments. In 1959, the American Dental Association recommended periodical hearing assessments and the use of ear protectors. Aquiring more information regarding dentists', dental nurses', and prosthodontists' hearing abilities is necessary to pr...

In this paper we present recent results on the development of the SynFace lip synchronized talking head towards multilinguality, varying signal conditions and noise robustness in the Hearing at Home project. We then describe the large scale hearing impaired user studies carried out for three languages. The user tests focus on measuring the gain in Speech Reception Threshold in Noise when using ...

When performing binaural spatialisation, it is widely accepted that the choice of head related transfer functions (HRTFs), and in particular use individually measured ones, can have an impact on localisation accuracy, externalization, overall realism. Yet HRTF choices speech-in-noise performances cocktail party-like scenarios has not been investigated depth. This paper introduces a study where ...

The purpose of this investigation was to determine levels of speech intelligibility between two submarines using standard transmitting and receiving units while in operation. Transmission and reception of prerecorded and live voice word lists was made using an AN/WQC-2 sonar unit with directional and omnidirectional transducer arrays. The lists were recorded at the point of reception and played...

This investigation measured the degree to which hearing aids degrade speech discrimination in noise. Ten normal-hearing subjects were tested for speech reception thresholds (SRT) in noise. The tests were repeated under two aided conditions: one used binaural behind-the-ear (BTE) aids, the other an experimental binaural high-fidelity aid fitted with in-the-ear transducers. To assess the loss of ...
