2. 1. Probabilistic Modelling of Hearing : Speech Recognition and Optimal Audiometry

   Author : Svante Stadler; Arne Leijon; Stefan Stenfelt; KTH; []
   Keywords : auditory models; probabilistic modelling; speech modelling; human speech recognition; hearing aids; cochlear implants; psychoacoustics; diagnostic methods; optimal experiments; audiometry;

   Abstract : Hearing loss afflicts as many as 10\% of our population.Fortunately, technologies designed to alleviate the effects ofhearing loss are improving rapidly, including cochlear implantsand the increasing computing power of digital hearing aids. Thisthesis focuses on theoretically sound methods for improvinghearing aid technology. READ MORE

4. 2. Computer-based speech therapy using visual feedback with focus on children with profound hearing impairments

   Author : Anne-Marie Öster; David House; James Mahshie; KTH; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Speech technology; hearing-imparment; speech therapy; visual feedback; second language learning; computer-based speech training; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

   Abstract : This thesis presents work in the area of computer-based speech therapy using different types of visual feedback to replace the auditory feedback channel. The study includes diagnostic assessment methods prior to therapy, type of therapy design, and type of visual feedback for different users during different stages of therapy for increasing the efficiency.

5. 3. Using the speech intelligibility index for evaluating speech test results and hearing aid characteristics

   Author : Lennart Magnusson; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; articulation index; hearing aid; hearing loss; speech intelligibility index; speech recognition;

   Abstract : Understanding speech is crucial for human communication. Therefore, speech audiometry plays an important part in the assessment of the hearing impaired, and improved speech intelligibility is a major goal of hearing aid fitting. READ MORE

6. 4. Influence of middle ear pressure changes on labyrinthine hydrodynamics and hearing physiology

   Author : Konrad Konradsson; Lund näs- och halssjukdomar Öron-; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; auditive system and speech; audiology; Pressure; Audiometry; Cats; Animal; Cochlea; Cochlear aqueduct; Ear; Eustachian tube; Hearing; Otorinolaryngologi; Human; Labyrinth; Otorhinolaryngology; Meniere s disease; audiologi; hörsel- och talorganen;

   Abstract : Results from experimental studies, as well as clinical studies, are used to elucidate the effects of ambient pressure changes on cochlear hydrodynamics and function. The perilymph pressure changes and the pressure release effects of the cochlear aqueduct (CA) and Eustachian tube (ET) in cats exposed to hypobaric pressure are elucidated. READ MORE

7. 5. Hearing in increasing age. Epidemiological and psychoacoustic aspects

   Author : Radoslava Jönsson; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Aged; Aged; 80 and over; Audiometry; Demography; Ear; Epidemiology; Hearing; Presbycusis; Psychoacoustics; Questionnaires; Socioeconomic Factors; Sound Localization;

   Abstract : Presbyacusis, age-related hearing decline, is the most common cause of hearing impairment in the more developed countries. Planning of health services for the hearing impaired requires knowledge of hearing in increasing age and in demographic changes. READ MORE
