  1. 1. A digital filterbank hearing aid

    Author : Thomas Lunner; Linköpings universitet; []

    Abstract : Digital signal processing hearing aids may provide possibilities for new signal processing strategies to compensate for hearing loss. However, to be practically usable in a headworn hearing aid the digital circuitry needs to fulfil requirements of low power consumption, low supply voltage and small size. READ MORE

  2. 2. Evaluating the process of change : Studies on patient journey, hearing disability acceptance and stages-of-change

    Author : Vinaya K. C. Manchaiah; Thomas Lunner; Gunnel Backenroth; Linköpings universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Patient journey; Stages of chage; acceptance; hearing disability; hearing loss; Patientprocess; Beteendeförändring; Acceptans; Hörselhandikapp; Hörselskada;

    Abstract : Person with hearing impairment (PHI) and their Communication partners (CPs) have a range of experiences and milestones before, during and after their audiological assessment and/or rehabilitation sessions. The term ‘patient journey’ refers to understanding the experiences and the processes the patient goes through during the course of the disease and the treatment regime. READ MORE

  3. 3. Climbing up the hearing rehabilitation ladder

    Author : Elisabeth Ingo; Ariane Laplante-Lévesque; Thomas Lunner; Gerhard Andersson; Margaret Wallhagen; Linköpings universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; online hearing screening; Stages of change; Motivational interviewing;

    Abstract : Hearing impairment is a major public health problem, affecting communication and participation, and is associated with a range of health problems. Most individuals with perceived hearing impairment do not seek help, do not opt for rehabilitation (hearing aids), and do not use prescribed hearing aids adequately. READ MORE

  4. 4. Exploring Cognitive Spare Capacity : Executive Processing of Degraded Speech

    Author : Sushmit Mishra; Mary Rudner; Stefan Stenfelt; Jerker Rönnberg; Thomas Lunner; Mithell S. Sommers; Linköpings universitet; []
    Keywords : Working memory; cognitive spare capacity; updating; inhibition; Arbetsminne; kognitiv reservkapacitet; uppdatering; inhibition;

    Abstract : Cognitive resources, specifically working memory capacity are used for listening to speech, especially in noise. Cognitive resources are limited, and if listeners allocate a greater share of these resources to recovering the input signal in noise, fewer resources are available for interpreting and encoding its linguistic content.

  5. 5. Cognition in Hearing Aid Users : Memory for Everyday Speech

    Author : Hoi Ning Elaine Ng; Jerker Rönnberg; Mary Rudner; Thomas Lunner; Kevin Munro; Linköpings universitet; []
    Keywords : Hearing aid; working memory; free recall; noise reduction; speech recognition; Hörapparat; arbetsminne; återgivning; brusreducering; taluppfattning;

    Abstract : The thesis investigated the importance of cognition for speech understanding in experienced and new hearing aid users. The aims were 1) to develop a cognitive test (Sentence-final Word Identification and Recall, or SWIR test) to measure the effects of a noise reduction algorithm on processing of highly intelligible speech (everyday sentences); 2) to investigate, using the SWIR test, whether hearing aid signal processing would affect memory for heard speech in experienced hearing aid users; 3) to test whether the effects of signal processing on the ability to recall speech would interact with background noise and individual differences in working memory capacity; 4) to explore the potential clinical application of the SWIR test; and 5) to examine the relationship between cognition and speech recognition in noise in new users over the first six months of hearing aid use.
