  2. 1. Perception of disturbing sounds : Investigations of people with hearing loss and normal hearing

    Author : Åsa Skagerstrand; Stefan Stenfelt; Susanne Köbler; Stig Arlinger; Arne Leijon; Örebro universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; perception; annoyance; loudness; hearing loss; Handikappvetenskap; Disability Science;

    Abstract : The present thesis concerns the daily sound environment and the human perception of the same. The sound environment affects the possibility to be active in a communication. With background noise, it may be harder to hear desired signals, and when suffering from a hearing loss, negative effects of the background noise increase. READ MORE

  4. 2. 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

  5. 3. Less is more? Loudness aspects of prescriptive methods for nonlinear hearing aids

    Author : Karolina Smeds; KTH; []
    Keywords : hearing impairment; hearing aid; nonlinear; WDRC; hearing aid experience; prescription; loudness; loudness model; speech intelligibility; preference;

    Abstract : In Sweden, about 10% of the adult population experienceshearing problems that cause them difficulties in everydaycommunication, and approximately 60 000 people are providedwith hearing aids each year. Despite the fact that modernhearing aids can facilitate speech communication in a widerange of listening environments, many hearing-aid users aredissatisfied with their hearing aids. READ MORE

  6. 4. 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

  7. 5. Hearing and cognition in speech comprehension. Methods and applications

    Author : Mathias Hällgren; Stig Arlinger; Birgitta Larsby; Arne Leijon; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Aging; physiology; cognition; cognition disorders; dichotic listening tests; hearing loss; sensorineural; neuropsychological tests; speech perception; Audiology; Audiologi;

    Abstract : Central auditory processing is complex and can not be evaluated by a single method. This thesis focuses on assessment of some aspects of central auditory functions by the use of dichotic speech tests and cognitive tests that tax functions important for speech processing. READ MORE
